Agreed!

As an FTR shooter, I've shot thousands of these. They're very picky about seating depth. A few thou in either direction can be a huge difference - So measure them to the ogive and not the tip. They also like to be 10-21 thou off the lands. Admittedly, that's what I know about them in .308 so we want them as long as we can get them. The method almost everyone around me in F-Class does is the ladder method. 10-15 shots in .1 increments, 10 thou off the lands. Find the flat spot you want (in 308 I see the same "big" flat spot somewhere in the middle and a smaller flat spot towards the top end for the high node). Once you have your velocity figured out, then start tuning seating depth, 3 thou increments usually. Again, very picky bullet, but when you find it's tune you'll be very happy. There aren't a ton of 300wm/wsm shooters in F-Class (near me, anyway.. 7mm rules the roost) but I'd like to hear from someone who shoots these in an open gun and see if our anecdotes align.

Just an opinion, but leverage from distance and capturing the vertical component of the shot fall is what an Audette Ladder was all about, with far less emphasis on the velocity values on the first runs. Velocity "Flat spots" with such small samples tend to evaporate, but group nodes that are strong by being a few charge steps wide tend to repeat. I would pick the vertical group nodes at distance, and then tune for seating depth the same way. YMMV Happy New Year!!!

@@edwinlongwell that’s the bullet I’ll always use at midrange (300-500-600 yards) it’s easy to load for and easy to manage recoil. Far less picky all around.

Shanon! I shoot this bullet in FTR competition. They are VERY picky with seating depth. You got a great node there with the short length with the first 4 shots! Load some up and shoot a group! Then run yourself a ballistics chart off Bergers website with that bullet and you’ll be amazed at how far out it stays super sonic! I really like your 300 Win Mag videos, and your new idea on the ladder test!

My understanding of this method is to find a velocity node via powder charge. And then use a seating depth test to shrink the group.

Johnny please try Federal 210M primers My 300WM did exactly what your loads did with every primer I tried until I got off the magnum primers and went to standard large rifle primers. It now has an extreme spread of 8 fps and will shoot 2” groups at 500 yards with a 180 accubond , 79.3 grains of H1000, 3100 fps average. Most people don’t know that the 300WM was developed using standard primers. In 1963 when it was released, magnum primers were not even being used yet. May not work for you but it really helped my rifle 26” Kreiger barrel, H&S stock, Jewel trigger, Remington 700 action

Love the return of the target cam. Thanks!

Don’t worry about accuracy, you are just trying to find the speed nodes. Then you go back and do an OCW around those nodes. Then do a seating depth test to tune to loads.

77.5 or 77.6 looks good to me now you need to find the seating depth. On my 300 wsm it was 120 thousands off the lands and my 300 win mag was 80 thousands off the lands. Good video. Happy new year

Great video! Yes, the 200.20x are all the rage in F -T/R. They took over from the hybrid 185’s.

Happy New Year glad to see you on tonight

In a savage 110 with factory bull barrel. Soft seat in to the lands. Bump .002 ish in a FL die, the shoulder, or sometimes just neck size. Trim the necks. H 4831 SC, 68.3gns. Berger 190 VLD, and those that your using. Holds well in the X-ring at 500yds. Clovers at 100yds. Primers show a little pressure, not much. But, 2000ish shots later, now I need a new barrel. 300win mags are hard on barrels. Fun to shoot next to the ar15’s and the firing line at a match with a sheet metal awning above you. Thanks for the video, been watching you make them for 2.5ish years.

I have another new Douglas barrel and have 500 rounds down the Douglas barrel on the rifle , you never know when barrel prices will increase or become difficult to find

I like the idea of testing different load develop strategies.

That’s the best ELR bullet I use in my .308. Very consistent out at 1800 yards. Going to be a little light for the win mag. Better to use the 230’s for that rounds but will work

I have done extensive .300 Win Mag testing with H1000, 215Ms and 200+g bullets, especially Berger, Hornady and Nosler bullets. Frankly, it is tough to find a bad combination. I usually seat the Bergers to provide .020" jump, the Hornady ELDx run about .045 and the Accubond LR like more jump at .070". In all cases, I set final neck tension with a .3065" expander mandrel and I think that's key. My best loads are with the 210g bullets and 77g of H1000. With 200g bullets, I'd recommend you look at that 77.5g plateau.

Hi JRB, I got better results with Retumbo in .300 Win Mag and my 7mm Rem Mag. Also find the heavier Bergers 220-230 are awesome. A lot of people saying that 200.20X is pernickety for seating depth. Best of luck in the development. Also I think that’s a brilliant use of shot marker combining accuracy at depth with velocity node search, Genius! May as well use the tech you have to reduce the steps needed !!

I recently got a chronograph and started using the 10-shot load development and I can definitely say it has worked out very well for me

Thanks, James.

I have a Browning BAR (Savannah) in 300 WM that I bought in the early 70's from the British Fleet club in Hong Kong when I was there on liberty. Been Reloading for 40+ years, 67 Grains of Winchester 760 pushing out a 150 Grain Sierra boat tail and a large rifle Magnum Primer (CCI). Tight groups at 100 yards but never measured them or muzzle velocity. Supposed to be 3100+ FPS but I don't have a chronograph so... No game I have shot ever got back up. Not exactly a precision rifle, but I like not having to manually cycle the bolt. A ten round Mag might be fun.

You might have to check belt headspace to shoulder headspace. If you’re coming in even +- .001 it can throw off the group, and you might need to add to the shoulder to stay off the belt.

I use the Berger 200.20x in a 300 PRC with 72.6 grains of IMR4955. Just under 1 MOA at 2970 fps. These and Hornady Atips are my go to bullets for long range steel pinging.

Love to see the MDT chassis! Got 3 of them myself!

Love me some 300 Winchester Magnum. Wish I never sold the one I had.

Very informative! I shoot the same bullet with 76.0 H1000, Fed 215M, OAL 3.563" = .65" 5 shot groups. 74.0 IMR7977, Fed215M, OAL 3.563" = .38" 5 shot groups. 73.5 IMR7828, Fed215M, OAL 3.563" = .5" 5 shot groups. I'm not chasing highest velocity. All loads have similar velocity so I think I've found the right velocity node. Remington 700, Bartlein barrel, Timney Calvin Elite trigger and McMillan stock.

Great video, lots of information. You need a different Freedom seed in that gun. Or different Barrel

Thanks! 👍👍

I’m just starting into reloading, I love your content, it’s helped me learn a bunch. In this video, I think you are adding too many variables at a time. Changing charge wt and seating depth to test for both may save time but seems to make it hard to pull the best combo from the data. I like the concept of the 10 shot load process, but I’m concerned with std dev fluctuations throwing off the data. I was thinking it might be better to do a 30rd test with 3 rounds at each weight to get a good average plus have std dev and spread data for choosing the optimal charge weight. Then progress to seating depth tests to really hone in. I’m curious about your thoughts on using 3 rounds per wt to find the ocw.

So many questions to ask...here are a few: will you be measuring your CBTO for each rifle before beginning seating depth tests? Will you be using the same suppressor on all guns? Can the information translate between the AR platforms and the bolt gun if the AR max length is capped by mag length which may limit jump to the lands?

Good stuff, in the progress of building a 300wsm

You got this neo

Great Vid!

Can’t wait for the 6.5 CM results! Looks like you are loosely following the Satterlee 2.0 method as outlined in the @LongRangeWithTheLillys vids. Keep up the great content.

I have a custom 300 win with a proof carbon barrel. I did load work using all the same components. I was getting crazy groups like you. After about 200rds I narrowed the problem down to the Peterson brass. My brass has “doughnuts” in the neck. I changed to lapua brass and the groups immediately shrank in size and consistency. Rifle is now a sub 1/4 moa rifle. Something to consider if you continue to have issues.

I'll start with the caveat that I shoot sling, so my accuracy standards aren't as stringent. I'm pretty similar when it comes to load development except I don't have a Labradar and don't like shooting accuracy with the magnetospeed so I just look for flat spots in speed. Once I choose a node I'll shoot a group and mess with seating depth if I feel it's needed, although at lot of times it isn't as I mostly shoot jump tolerant bullets. I've also been dabbling with OBT lately too. A good example is with the load development I just did with Reloder 15.5 with 80.5's in my service rifle. I ran a ladder and happened to find a nice node around 2825 fps which in my experience has been an accuracy sweet spot in a 20" service rifle. I tested 3 loads in that area and the winner ended up being 2826 avg with a SD under 10. At 300 yards from the sling it held 3/4" elevation. 4 shots grouped into .33 MOA with either error or wind on the 5th opening it to .66 MOA. It's pretty nice when you can find an awesome shooting load in 20-30 shots.

Ok so I use this “Saterlee” method religiously. I swear by it. It saves me so much time, bullets, powder and PRIMERS!! lol Anyhow you have the right idea on looking for flat spots in velocity like your chart shows. I look for those as well. But also look for valleys. I have had better luck with dips in velocity between charge weights. The red line I see a really nice valley between 76.0 and 76.5. I would now load and play in between those charges. Load 3 or 5 at 76.0, 76.1, .2, .3, all the way up to 76.5 and shoot for groups. Once you find your velocity node then play with seating depth. Don’t try to do too much at one time. For me I always seat at .020 off the lands for lead core bullets and .050 with any solid copper bullet when shooting for a velocity node. If I can’t find accuracy at those seating depths I’ll play with seating depth a little but still using my best verity node charge weights. But generally I don’t have to do that. Especially if I’m using a tuner.

I think you should go by the powder charge and look for the plateau. The powder charge determines the accuracy more so than the seating depth. Looking for accuracy in the spikes and dips is going to be futile I think. From my experience anyway....

After watching all your videos, I feel like I owe you for student loans. Thanks for all the free content buddy!!!!

great bullet for F-Class in 308W(in long heavy barrel with custom chamber), but not at the same velocity, maybe don't work in magnum calibers. Also without suppressor to try small groups.

Have never loaded anything that size. The charge weight is well above my personal record.

Vertical dispersion seems tells the tale of what's going on to me when I'm doing load development. I would compare the Vertical dispersion between the shots on the plateaus and see what that looks like.

Does having the plateau at 77.4 and 77.5 on all three seating depths show that that would be a better or the best accuracy node?

I'd like to see some group testing in that 77.4gr - 77.7gr charge range. All three seating depths did well in that area and I'm curious to see what groups and SDs would look like. Might provide some validation to the theory or it might shoot it down in flames, but only way to tell is to test it.

In comparison I look at what the average velocity in your graph. When I do that test while using different powders I look at the area where it seems like the node is the velocity in this test regardless of the charge weight of any given powder from what I have experienced.

You originally mentioned that the velocities seemed pretty high. Then when you used the shorter length you dismiss the best 4 shots group you had all trip, which was at a more reasonable velocity. Why not try the shorter length and load some five shot groups in that region and a couple in the other higher velocity node With the longer length. Jumping around to other calibers in an Ar rifle isn’t going to give much information how this combination is going to run in a bolt gun. I will still watch the other videos though.

I do this test. I load ten or so rounds at the same depth and jump .02 grains. I do not shoot at a target, just over the chronograph at a berm. I then graph my data, find the flat spots in the graph and load rounds at those charge weights to check for group size. I will usually also load all the weights in between those charge weights and test them for group size. Smallest group wins. Sometimes I will check seating depth in an attempt to improve group size.

I think that slowest and shortest length offered some good results. I would try and see if you could line of speeds with groups across the 3 different seating depths and ignore the seating depth and see how they were grouping in comparison to speed. But that bottom of the shortest had the best 3 shots that grouped.

The best oal seems to be the long. It produced your tightest grouping. 76.8-77.8gr at that oal produced you latest velocity curve. I think I would shoot a 5 charge weight ocw test at this oal or at 77.3gr shoot a seating depth test at 0.005” increments above and below this oal. Following standard logic, I would do seating depth first.

I had a Remington Sendero in 300 WM and my groups were pretty similar no matter what I’d do. I sold it. Strangely enough I had good results from 150 grain sierra game kings I loaded just to see how fast they’d go.

Im trying 10 charge weights 3 per charge hope this will show me sd es and speed nodes also on depth im finding jam point coming back.020 for starting point on my rifle touching land point and jam point varied a fuzz

What about Hybrid 100V powder? I switched to it in my 6.5-284 over H1000 and got better SD numbers and velocities.

One of the competition shooters I watch on youtube, says he does load work up by shooting for best SD/ES. Then he focuses on group size by adjusting seating depth. I just wonder if getting a load where the powder burn settles and has single digit deviation, if and by how much, the seating depth affects the SD's. I vote you test it in a future video. lol

I thought it would’ve go little faster. My 30@ rum pushed the 245 grain Berger’s at 3140 fps with no pressure and I have it pushing the 230’a at 3225 also with no pressure but that’s also with a 32” barrel. I don’t think anything under 230 with the rum is a waste and should just drop down a size but that win mag is a beast. Very nice rifle. Barrel to short for what I do but nice rifle

I have done a number of Satterlee tests in several calibers with various bullet/powder combinations, and I can say with absolute confidence that I have no idea if it works or not. I think you're on to something with two shots with each combo, that should give a lot more data points. They might not be useful, but you'll have at least twice as many.

Good to see you on tonight

I'd say your problem lies either with 1. variation and unevenness of the neck thickness of the brass, 2. variations in the Berger bullets, especially ogive, boat tail and weight and 3. powder burn rate; not 100% of the H1000 might be burned before the projectile leaves the barrel. I especially observed that boat tail designs lead to more flyers if point # 3 is not achieved especially in combination with minute tooling marks in the crown. If flat bottom designs and boat tails exist in the same weight class, usually the flat bottom ones group significantly better if point # 3 is the problem. I always check "Quick Load" before choosing an adequate powder that burns 100% within the given barrel length and caliber. Just on the side, if you witness muzzle flash your powder has to slow a burning rate.

New to reloading. Why worry about making high velocity does it need to be fast to be accurate?

Anyone have good recipes for reloading 45-70 lever gun?

I thought the upper end looked the best but I didn't see where the holes where on shot marker

Yea 300wm vid. The chickens are happy

I would do 77.5 and test seating depths in 3 thou steps from the longest length out at least 10 and better to go 15 steps. Even two shots at each step for a 30 shot test.

they say this powder a little slow , but I am trying this in 6.5 prc with 147 with a 24 inch barrel

Just wanted to let y'all know CCI #41s back in stock at midway limit 1000 per customer while supplies last.

its always frustrating not getting consistent data my guess is your gun doesn't like either the bullet or the powder

If you do the test with the 6.5, 5 charge weights at 10 lengths change your lengths to .03.

Can't you digitally overlap the 3 shotmarker groups

Scope or mounts not holding zero?

Originally Scott Satterlee said to do charge weight testing then oal testing but in his newest video with reloading with the Lilly’s he said to do oal testing first then charge weight. Either way your test here is very interesting. Your videos are great keep up the great work.
