You can have my number bro. It's 903-513-GO-F-URSLEF-KYLE

ARs are not hunting rifles according to some here.

RR, no, the powder I use is not listed in your results. The powders you listed cover a very broad array, and include some powders you would not use for a 308.

Ok, so let's "calculate" using QL. And I say calculate, because QL gets you in the ball park, as you probably know. (My field data and field results show an even better picture with velocity gains with faster powder in the same weapon).

Varget is a great powder for the 308. It is commonly used for maximum velocity in the 308. To pick up speeds in a short barrel, shooters often want a lighter bullet, so let's use the 125 grain Hornady SST bullet I have been shooting. I have a powder I use for this lighter bullet for my SBR or shorter barrel rifles, especially for AR's shooting suppressed. My "mystery powder" is much faster burning than Varget. Let's run the numbers.

In a 22", 308 Win bolt gun with 125 SST at 62K psi, I "calculated" 50.1 gains of VARGET shows 3111 fps and 95.7% burn rate (4.3% unburned). Put this same load in a 16" barrel, and you get 2886 fps, and 92.8% burn. So, there is about 7% of unburned powder coming back into the action. In an AR-10 platform, the gas port is 12" away and would have 17,300+ PSI at the gas port.

Now, if you run my "mystery powder" at 62K psi and 125 grain SST, I'm using much less powder than the 50.1 grains, in a 22" barrel I show 3043 fps, 99.8% burn rate. In a 16" barrel, I'm "calculating" 2841 fps and 98.8% burn rate. But my field data is running another 80-100 fps faster than this QL calculation is, which tells me it's even more efficient than that. And at the gas port 12" away from the chamber, the pressure is 14,900 psi, which is 2400 psi less than the Varget load.

What does all this mean? A faster burning powder engineered for short barrel rifles will have more velocity than a slower burning powder, less gas port pressure, use much less powder, and have a more complete powder burn for keeping your weapon much cleaner. We have already seen these results in our AR's from our night hunting. It's a win win.

"Size Matters, Smaller is Better"

Thats what he said

"Size Matters, Smaller is Better"

Thats what he said

my little friend with my son from a few weeks ago..
he was like "dad, I REALLY like this gun"
He has a tendency to try to make my toys his own..
I was in his room last night and commented on how 3 of my guitars ended up there!

Absolutely agree with that. QL can't predict or calculate accuracy, but it sure is handy for harvesting hunches and staying occupied when you have time to kill. I can't find a "suppressor fouling" column in my QL either.

I think it's not the size of your package, but how you use it!

That's what my ex used to tell up until the day she left.

Man, I hate to stereotype but.....Asian
