Really awesome episode guys. As a maybe intermediate reloader, the relationship between pressure and case volume is something that always made sense to me. I never really thought about the bore volume in its relationship to pressure though. the discussion about the 9mm bore being the same diameter as the case and why that requires the much faster burning powder as opposed to rifles just clicked a whole bunch of puzzle pieces into place in my brain. Thanks for releasing this!

Excellent podcast as always. It's great to hear the experts talk that actually know whats going on. Could you guys do one on primers? Small vs large, standard vs magnum? Thanks

Another aspect of bore volume vs. burn rate that didn't get mentioned is barrel (bore) length and its relationship with burn rate. Using your example of the 9mm vs the .243, the 9mm bore volume does increase faster, but since it is much shorter (usually), the volumes will end up being similar...but the 9mm powder needs to be faster not only to fill up that more rapidly increasing volume, but to also finish burning in the shorter barrel.

​@@chipsterb4946Another factor specific to revolvers is the cylinder gap concept. Longer barrels in the presence of a cylinder gap actually may decrease the velocity of a given cartridge, usually observed with barrels over 7 inches. I have first observed this with my Ruger Single Six revolvers shooting 22lr, 6.5 inch barrel gives faster speeds compared to 9.5 inch... I also observed this concept after started reloading for centerfire magnum revolvers..

Thanks guys for running through all this info. I keep mine in ziplocks with 50 % humidor packets.

I wish all industry media was this useful. Most of it is infotainment that’s devoid of any real meat.

I believe you made an inaccurate statement about surface areas of different size granuals. You said that larger the granules, the more surface area it would have compared to smaller granules. The smaller granules of the same volume as the larger granules would have more surface area due to the percentage of the flake or granual that is exposed. This leads to a faster burn rate for smaller flakes. Think of it in terms of something like ice. Ten pounds of crushed ice will melt faster than a solid 10 pound block of ice due to the percentage of surface area exposed to higher temperatures than 32°. This is one of the reasons that flake powder, such as shotgun or pistol powder, has a faster burn rate than an extruded rifle powder. I'm not trying to be nit-picky with your podcast. I enjoy every one of them.

Love to see another podcast on advanced powder, which ones deteriorate and why, more storage tips. I vacuum seal mine, I wonder if I vacuum the air out of the cartridge it’s bad? Should I let it equalize prior to using?

I had come up with an unbelievable load with superformance for a 6.5 when it was winter out and no pressure signs used the exact same load in the summer when it was hot as hell out and ammo was sitting in the sun the pressure was unbelievable. Blowing and piercing primmers. Pressure was beyond excessive

Another great episode.

Great video Always learning something.. Really interested in finding out what powders are are better for long term storage.

One thing I wish you would have covered in this podcast is similar nomenclatures among different brands and why one can be good for a cartridge and one wont be. Example IMR 4350 and H4350. How did they come to have the same # in the name and how can they be vastly different.

Great information! Would be great to have a second episode on powder to get even deeper. One thing to talk about is why propellant is NOT done certain ways. For instance: - Why is propellant not in the playdough state? Couldn't the burn rates be controlled chemically and nullify shape? - If nitroglycerin is used, why isn't plastique used in propellants or even instead of nitrocellulose? - Why doesn't firearm ammo mimic artillery ammo in terms of having preset charges? These charges could easily be dropped into a cartridge, or going back to muzzle loaders and eliminate the cartridge? - I know there was a firearm built in the 1960s that used jet fuel that flopped of course. - etc, etc, etc....

As a retired 13A who cut his teeth on 105s, outside of maybe a muzzleloader, I'm not sure what utility varying charges would have for firearms, given the narrow band that small arms propellants work in for a given case and projectile. Howitzers have to be able to fire "accurately" at relatively higher angles (usually over 267 mils or 15° to prevent a ricochet in a training area situation) from 2000m to 30km. That tends to be best accomplished within certain range bands within a charge, dictated by probable error data found in Table G in the firing table. A squared away combat Fire Direction Center would have a range fan with those bands on it on acetate. I happened to have an old 155mm firing table on my end table.

There is a good write-up regarding pressure on page 55 of the Speer #12 Reloading Manual. They look for an average expansion of 0.0003 with no individual reading over 0.0005". They state that this is generally accepted as representing pressures in the 50,000 CUP range with typical cases. Cases used more than 3 times become work hardened which result in false readings. Hornady comment on this on page 72 of their Hornady Handbook of Cartridge handloading, 8th Edition. " An accurate blade micrometer can be a useful instrument for detecting excessive pressures. By measuring new case dimensions before and after firing, you will be able to note signs of excess pressure. On belted magnum cases you should measure the belt. Careful measurement of this dimension of new cases before and after firing reflects chamber pressure. Measure rimless cases just in front of the extractor groove or rimmed cases immediatly in front of the rim will reveal symptoms of excessive pressure in these cartridges. When these results are compared to similar measurements on factory rounds, a reloader can approximate a safe upper pressure limit."

Can you talk more about sealing ammunition in a future episode. For those of us that live and load in a certain environment, but then travel to hunt and/or shoot in another, this may be a worthwhile thing to consider.

Love this one. Good job

25:30 Wait, you mean to tell me that there are reloaders out there who haven't poured out a small amount of propellent and took a lighter or match to it? Hell, as kids, we used to take fireworks and open them up to get the powder out of them and into a mound and light it, where I'm from, we called them "Genie's" because it was like the flash and smoke plum that would appear right before a Genie came out of the lamp in the cartoons... Speaking of which, since 4th of July is just a few days away..... LOL What is explained starting at about 40:20 is also basically the explanation of why seating a bullet deeper off the lands will _"typically"_ cause a reduction in overall peak pressure for the same charge for anyone who's ever wondered that. If the bullet gets a running start at the lands, it is easier for it to engrave into the lands and keep going (i.e., total case/chamber and barrel volume increasing at a more consistent rate) whereas a bullet seated out touching the lands (or really close to or worse, jammed) do not get that running start and therefore is taking more force to initially get going. This results in a total volume that is not increasing as fast as the gasses are being formed from the burning powder so pressure rises faster which in turn, as mentioned earlier in video, causes the powder to burn faster, which in turn causes the pressure to rise and the cycle repeats until the bullet really gets moving down the bore.

Please consider a podcast on explaining the difference between loading for auto loaders vs bolt actions and why someone should not use your .243 rifle ammo in a semi-auto.

Excellent stuff guys!

Great discussion. I would really love to know how much of a discernable difference you can expect from different lots of the same powder. For that matter, bullets too.

@milesn3173

Жыл бұрын

This would be very difficult to properly quantify. Suffice it to say that at a minimum I definitely re-test or re-develop a load with new powder lots to match velocity of a known previous lot of powder, then evaluate dispersion performance. Bullets tend to be less of an issue, but we've seen a few instances where different tooling used in different lots of the same bullet can cause minor POI shift between lots. This is also something worth testing. The old rules of thumb of re-testing after changing any component/lot is solid advice, and buy in bulk whenever possible.

I use H4350 for .270 Win, H Varget for 30.06 Sp. H1000 for 6.5 PRC.

What's holding us back from large pressure increases, traveling charges or some way to hold a longer pressure spike, and good sabots especially ones that could be used in a smooth bore? It seems like to me we are just refining the technology from 100 years ago and some things with advancement in materials and technology like 3D printing we should be getting close to a major jump.

Another insightful podcast. Thanks. As a handloader, I would have loved to see each of your individual approaches to developing a starting point load from the Hornady Handbook and in a caliber which you've never loaded.

does adding sealant to the case mouth and primer affect pressure enough to change accuracy?

for Jayden and Miles, would be great if the burn rate chart can be updated, say each with a number/score out of 100, ie 2 powders can be next to each other, but closer to the the powder on it's other side then each other... I know you can alter it by temp and volume (ie seating depth).. What i'm thinking is rate chart where each have a score, the power was say occupying the same % of space in a container - so as to level the "playing" field.

Simple rule prevents wrong powder use, only 1 powder out at a time! To include swapping, cleaning, changing all devices. Powder chucker, trickle charger, ect. 1 powder means everything! Human complicity is the demon!😮

I only burn powder that is temp sable, some of the powders mentioned are horribly temp sensitive and get crazy with high temps and humidity.

I have always handloaded, beginning with the ww2 milsurp stuff. I sized flashholes, weighed cases and thought I was prudent. This podcast taught me all kinds of things. Question about the powder column configuration. Wouldn't a long narrow powder column provide a more consistant burn? The opposite of the newer short/fat case design. A smaller diameter case , the column directly over the flashhole( with a full column) should me more consistant. I have always thought this and you suggested that if the column slumps away from the flashole the burn would be less consistant in theory( as I got this) Would not a long powder column of a .375 H&H provide more consistant results over the .375 Ruger? Especially with a less than full chatge. Regards, Tony.

I've always wondered when looking at actual velocities of a personal rifle vs. the velocity of a charge weight listed in a manual, can the charge weight be increased until my velocity matches the book velocity? assuming the barrel is the same length as what was used in the manual. maybe a better way to ask it is, is the velocity in the manual, a better indication of max charge than the weight listed is? I've noticed that different cans of powder have required more or less powder to get the same velocities as other cans of powder.

@herbieschwartz9246

6 ай бұрын

Short answer - do not just add powder until you get book velocity. Too many variables involved. Start low and carefully go up from there, looking for pressure signs. Don't just go for the max and feel safe because its "published data". If you have ever seen a gun go BOOM because a reloader is chasing velocity, then you will understand that being safe is the number one priority.

does adding sugar to the propellant, in the manufacturing phase increase energy?

All I want to know is what kind of powder you guys are using in your 7mm prc 175 grain eld-x shells and how much?

What is used to seal ammunition at the primer? Same the bullet end?

🧐 Wouldn't I expect to get better accuracy out of a powder (out of my 270 Winchester) with IMR 4831 - because it has less grains - than let's say Magpro (if I was using both to their maximum load rate and if both (as you say) filled the case so their was no empty space left to vary the ignition distribution within the case, even while shooting on a slope/hill)? 🤔

Reloading for 300 win mag. Wondering if case fill isn't full, can you adjust seating depth to help with that issue and see better results?

In your testing for how the temperature affects burn, have you noticed a minimum temperature that ammunition work better, say 90 degrees or so?

24:00 actually in a video with Joyce Hornady years ago, he shows lighting powder. I think it might be one of his reloading videos he did. EDIT: Haha, Jayden just mentioned that video.🙂

This may be a dumb question, but how does seating depth effect velocity?

Dear Hornady, if I wanted to reduce my powder charge of a larger case volume to slow down the projectile speed (say 108 eldm from a 6 creed) to say 2800 fps, but still wanted to remain near or at max case fill percentage, would it be safe to switch to a slower burning powder than say an H4350 burn rate, to allow the case fill to reach back to a full case fill?

@milesn3173

Жыл бұрын

Generally, yes. Slower burn rate powders will typically fill the case and reduce muzzle velocity and peak pressure. Obviously it's always best to have book data to start with for a reference point. You may run into ES/SD variation that's less than desirable with some combinations, and sooty, dirty burns with slower burn rate powders.

Powder burn characteristics vs. moisture content: Norma's Reloading Manual No.2 has a great article on the topic, with measurements!

Overall this video was fantastic. Like others, the “bore volume” // the size of the bore in relation to the chamber/case body hadn’t occurred to me as a factor. Wow! I had no idea that temperature fluctuations over time could affect propellants. Thank you. I found the “3 legged stool” metaphor a little confusing. Geometry I understand - more surface area burns faster. Chemistry makes sense in terms of coatings to control the burn rate. However, “pressure” doesn’t seem like the right word choice. I don’t know whether “energy per unit of weight” is what he means or energy as controlled by case and chamber geometry or what. For example H4895 and VV N-135 are very close on burn rate charts, but look at the weight of powder for a maximum load for a 165 grain SST. Max load shown is 43.3 grains for H4895 but only 38.7 grains for N-135. Granted the N-135 max load is a little bit slower (2,533 vs. 2,600 fps) but even if you down-load H4895 to match velocity you’re still going to need more powder (by weight).

I love the smell of gun powder in the am

There was some experimentation on something similar to what you are suggesting, but was found economically unpractical, They ran a small powder filled tube from the primer to the front of the case to initiate ignition at the front of the case first with positive results.

I'm don't reload and I definitely don't know much about it but, I have bought some reloads (5.56) from freedom munitions and it was the worst ammo I ever shoot. It had a light load of gun powder and it was very dirty burning and corrosive and wasn't accurate. If you let your gun sit more than a day without cleaning it, it started to turn green. On the other hand, I got some of the AAC 77gr otm ammo from PSA and it's very accurate but dirty burning at least it's not corrosive like the powder freedom munitions uses.

Is factory ammo sealed around the bullet and primer?

what does the application of sealant have on the pressures all other factors being equal?

Interesting 🤔 Hello from Ukraine 🇺🇦 Thanks for sharing expertise 😊

I did some wildcatting where there was no load data. 6mm Remington Ackley, 338 JDJ #2, 308/350 Rem Mag (belt machined off), and others. Regardless of what the "experts" say, load development is 10% science and 90% voodoo and if you think otherwise, then do not attempt to work up loads without established load data or you may experience laws of physics that can hurt you very badly. Working up loads is done slowly with careful measurement and documentation. Eventually I found powders that liked my cartridge/ bullet combinations without large surprises in small increased powder charges. If you are working up loads from scratch, expect a lot of time and effort. If you want to cut corners and "assume" based on similar cartridge capacity, etc. then expect an unwanted result because eventually, it will happen.

Do powder manufacturers publish a progressivity chart or a "burn pressure chart" that characterizes how the powder burns to sustain maximum pressure for the maximum possible time?

It would be helpful if the ammo companies ahared what powder they used. Feature it like they do bullets.

Since they are made of the Same Chemistry, wouldn't the highest velocity come from the one with the larger surface area (H4831SC) and the Accuracy come from the one with the least amount of grains (H4831) because it's packing would have less variation? 👨‍🏫
