Awesome. I have always had trouble zeroing as I was never taught thoroughly. Thanks.
Run David Tubb chamber and bore lapping rounds through it. Gets things smoothed out without having to put a tons of rounds through it to get it to group better and run better. Great advise on everything, too many have missing content on what to look for and why. I new it was bogus on the mag myth but never knew why, Thanks!
Thanks for your time sir
Learning more than what I did in active duty...Thanks for shearing. Like all your videos, specially Basic Dudes Stuff.
Interesting zeroing method. Makes plenty of sense compared to walking back and forth from the target five times! Yeah, my BCM MK2 (which i love) had a bit of a break in period. So did my Aero Precision EPC. Never knew that about hydrostatic pitting either; interesting point. Maybe that group could tighten up with a different grain, maybe. Rock on. Thanks for sharing your thoughts, Pat.
300blk is definitely one of those rounds you have to find what your gun likes. I went through like 10 different manufacturers before I found a load that grouped acceptably.

I shot an 8.5” 300blk with a Ballistic advantage barrel on it and couldn’t consistently get better than 4” groups, swapped a voodoo 8.5” into, all other components the same (all cleaned prior to firing and after break in) and got sub 2 MOA groups with best being 1.43”. All with bulk federal American eagle 150gr factory loads. I noticed the chamber in the voodoo was significant tighter and compared casings with the case mouth out of the ballistic advantage being .08-.21 larger than those out of the voodoo. That chamber tolerance appears to play a significant role.

Always excellent content
You hit on three really relevant points. I remember when I was training in the early. 80s NCOs who carried rifles & rucks for a living in Viet Nam really stressing the importance of not resting the mag on the ground. No war stories that I remember to go with the admonishment, however. We always zeroed on sand bags anyway. I also don’t recall in the early years of my uneventful military career ever getting near a BRM range that had us using anything other than 20s. Maybe TRADOC and ROTC were trying to use up the existing stocks. The second thing you hit on was the importance of cleaning the bore. And finally, the one thing that I can really relate to is to not forget the cheaters when planning to adjust optics or sights !
@Gizmus123

In 07 we were still using 20s for group and zero during BRM in basic. They %100 appeared to be from VN era or somewhere near to. Bluing and finish all worn down, etc. Never saw another one after that.
Thanks for the knowledge no one every said that was why you never put your magazine on the ground.
Learn something new every video 🤘
Try a Noveske. If you can find one. Mine shoots an sweet group.
You should shim the barrel extension with .001, .0015 or .002 stainless shimstock. Ar's can have some wobble if the barrel extension is not tight against the upper receiver. I've noticed its a bigger problem with AR10'S than AR 15's. The other option is to get the upper from JP enterprises, you have to heat them up to seat the barrel, but they're super expensive.
Great video
I'm getting my first ever AR and I never heard of or knew about hydrostatic pitting....cool!
Getusome! Thx Pat
Thx man. Great simple Vid
Pure awesomeness.
Pat even makes zeroing watchable
👍 I pin an upper in a vice..remove the bcg..look through the bore at a spray painted dot on a tree 100 yds away and center it in my bore, then center the red dot on it, then adjust my flips till red dot floating just over front sight post, then center in rear flip, gtg. My edc is 7.5" 7.62x39..no tack driver..gtg
I have the exact same upper and with good ammo my groupings look the same as yours. When I put a Surefire 300sps on the rounds were tumbling at 25 yds. I bore scoped the suppressor and couldn’t see any thing that indicates a strike but I’m going to send it back to Surefire to check it. I was pretty bummed out with the results all around.
thanks for clearing up the mag rest issue for me

With that length of .300 depending on ammo, you should be ok. Since it usually burns all the powder in like 8ish inches. Again, all that stuff varies a lot and a ton of what ifs to manage. Hopefully it gets sorted out. Thanks for the info Pat.
I have both my hunting rifle 16" and 8.5" pistol zeroed at 50 with supers and a "drop table" for subs. I handload all my blackout so that's my personal setup. We still had general issue M14s in the navy until I left in 07.

Great Idea! I have a 8.5" sbr I pig hunt with and go back and forth with supers vs subs. Been wanting a better system other than re-zeroing all the time.
Just picked up a new Christensen Arms mesa in .308. Started the break in process they recommend which takes 50 rounds. To me this seemed excessive but I thought what the hell I got nothing better to do. After two cycles of shooting then cleaning, groups went from just over an inch to under an inch for the next two cycles. Cycle being fire two 3 rd groups then clean. I bet that 9 inch will tighten up with a little break in.

heh, 9” at 50m is like an 18 MOA rifle. not so good outside a hallway.
We would have certain gun/magazine combos where putting the magazine on the ground and then loading it would cause malfunctions at SFARTAETC. Usually it was older lower receivers.
My friend taught me to sight in laying down as well . Beats a table that will move Everytime u shoot a round .
Oh crap, I didn’t know about cleaning the barrel of a new upper. I just bore sighted with the irons and then the red dot before going out to the range. Learned something new today and yes, I’m new to the AR platform.
At OSUT in 2009, one of the first things they taught us was HOW TO use the magazine to stabilize the rifle. Glad we had a company of Drill Sgts that knew there shit. A couple of them were ex ranger batt. Im sure that helped

The pitting would come from the speed of the round not the size/mass. Faster round will cause pitting.

Try using .25" graph paper, draw your own 1" bullseye, 4 per sheet. Easy to measure for sight adjustments. 5 rounds per adjustment. Start at 25yards. Any off the shelf rifle should put 10 rounds into 1" if not you need some skill training. Then go to 50 yards and on.
I need my readers too. Kinda sucks. Can’t go anywhere without two or three. Good info.
I noticed those new BCM charging handles come with some stiff springs making in somewhat hard to charge at first but after some break-in it'll be like "grease butter"
I get consistent 1.5 MOA at 50 yards (.75” groups) with my DD .300 using Sig and Gorilla subs. I am sure you are a better shot than me so something ain’t right there. Oh and my vision is shit too. My money is on that upper = no bueno.
Glad you did this with 300 black. I was considering a very similar build but may end up going back to 556 with that grouping.

My very layman philosophy is whether I get shot in the sternum or 2 inches low and to the left really doesn't matter all that much. Same with caliber- I don't want to get shot by .22, 223, nor 300 BLK, etc. (is that "basic dude stuff"?). Good luck with whatever you decide to build.

@paulsred65 Well I know Mac is a much better shot than me, so the chances of me getting good hits with that are much lower. My inaccuracy + the limiting inaccuracy of the equipment is too much for my comfort.
From what I have found for research, under 10" of barrel length with 300blk the groups will struggle. I run supers and subs. Suppressed and un suppressed. With my 10" barrel, the supers have crappy groups. The subs however are tighter
Damn. I zeroed my Noveske 300 blk out upper the other day @ 50meters and literal got .25”-.5” MOA groups. I had good luck with the Hornady black Vmax 110gr.
Would love to see one on zeroing an acog
You would not need to wear readers to smoke me in any shooting contest. Respect
Thanks for this video, I just got done zeroing my 8.5 black out, and was wandering what was up with my group. Because my 62 gr 5.56 is about a 2in group and my blk out is more like a 5 in. I thought I was wrong, glad to see it’s the 30cal

The other reason the instructors taught people to keep the hand off the bottom of the magazine is because if you shoot with a plugged bore, the M16 is designed to vent through the magazine well and blow the bottom out of the magazine instead of it coming back in the shooter's face.

He does mention its 50yds at the beginning and the 50yds to 200yds isn’t equivalent to the .300blkout. 50yd zero will be roughly 8-9” drop at 200yds with supersonic rounds.

Nice history lesson with some shooting. When did the Marine Corps switch from M14? I enlisted in 1999. And we were using A2. Never had the opportunity to shoot M14.
I handload for my AR 10. I have been working on a super light 100grn Hornady bullet that I absolutely love. It's fast, lower recoil and really accurate out of my rifle. That 300 bo in my opinion isn't worth a shit. The only advantage is the 30 caliber bullet but you loose every other advantage due to the cartridge.
i have my process for zeroing a rifle scope down pat (pun intended): a 50 pack of flamingo lawn ornaments & a fresh bag of big league chew -.-
Yep, the 300 Blackout is a totally different animal... With that said,it has some things to bring to the table our standard 5.56 just cant do, especially in this short of package.. If you have a few moments take a look at Johnny's Reloading Bench, he has probably one of the best video series on the 300 Blackout, which even if your not into reloading for the Blackout, will show that your 9 incher can be very accurate with the right projectiles, powder, case prep, and assembly... He also has demonstrated that his 8.5 " gun is quite accurate with as mentioned ( quality loads ) a decent scope ( or Aimpoint ) with a decent trigger, and time... You have a good barrel and set up so, you should be able to achieve similar results as a 5.56, just within shorter distances. Unfortunately your at the mercy of the ammo manufaturers, who have to try and build ammo to fit a wide variety of chambers on the market, which may not suit your chamber as well... I have used Barnes 110 gr Black Tip's for good results as well as Hornady 110gr Gmx load, both of which the projectile was developed specifically for the Blackout cartridge, helping to develop both velocity and accuracy in that platform. I have been using BCM's 12.5" barrel for just over a year now, and with the 110 gr projectiles I can push them very close to the Ak 762/39 rounds... 2,350fps... Take care Pat... Still doing the Lord's work...
I use Hornady 190 subsonic and it’s devastating on pigs. Drops 8” at 100.
