Ok so they were out of the powders I said they had, oh well. So I bought some IMR 8208 xbr, I guess we will see how it works. It is a stick powder but the sticks are smaller then the h4895 so I think it will meter well, but I will find out.

I think 8208 can be tuned to shoot the heavier .308s. (see photo below). And the kernels are about the same size as most ball powders. Another powder that is a very small extruded is RL15. Just a bit larger than 8208. Meters better than most sticks. And I know personally that it can give you fairly consistent sub MOA groups. (see photos below) For the past six months, finding RL15 is about like finding hen's teeth. But it's slowly coming back on the shelves.

I've heard that AA2520 had that nickname. But I've also heard that it was a nick name that was established about twenty years ago and that it may no longer be the "Camp Perry Powder". Have you personally used it in a .308 auto load or any .308? If so, what kind of groups are you getting? I’m curious enough about it to try it. But I haven’t heard or read anything about the size groups it can give.

I don't own a 308 semi-auto, only a bolt action 308 rifle but I do shoot with a few friends who do and we talk about loading all the time. One guy I shoot with and talk loading with has been at it well over 40 years and I trust his opinions. (and ammo)

I have shot plenty of .308 ammo in a semi-auto with IMR4064, BL-C(2) and AA2520 and while I prefer IMR4064 the ammo using AA2520 is very accurate in an AR-10.

We usually shoot the semi-autos up on the mountain because the local range has a 3 round limit in rifles and we don't usually put out paper targets. There are no benches so we usually shoot at tiny little rocks, twigs and clumps of mud up the side of the hill...

I own and shoot an AR-15 and AK-47 and I have never shot them on a bench at paper to measure groups either. IMO that's not what those rifles are made for although I know these days they can. At 75 to 100 yards the AR-10 I shoot with a 1-4X32 scope can hit clumps of mud that are ~ half dollar size. I would give you info on further distances but where we shoot we can't safely shoot much past 100 yards because of the limits of the natural backstops. (sorry)
