Home Forums Hunting & Shooting AR and Tactical Rifles What do you guys think about AR Comp from Alliant?

I found some of it locally and wondered if it was was worth fooling with?

I just started working with it last week. Supposed to be consistent across temperature extremes. I just read in a gun mag that it is supposed to have copper fouling reducers in it.

I find it meters very well, and looks like it will provide higher velocities than the older powders.

Sorry. I have not have time to actually shoot it yet, but the only newer powder I've used that doesn't meet the PR is Superformance, so I figure it should work, if not well, at least adequately.

I'm liking it so far. Like Scott says it meters really well. I've only loaded up 55 gn sp with 24 gn of AR Comp so far. Shot really good groups. However at 24 grains that case is practically full. Not going to be able load much more than that in a case.

I have an AR I couldn't get to shoot until I came across AR Comp and 53gr V-max bullets. Now 5 shots into 0.60". I like it. The same load shoots well in an X-bolt I shoot.

I finally found some, quick load promised insane speeds with it. The problem is its too slow for bullets below 65 ish grains. I still produces what most would feel decent speeds with lighter bullets just not the top end.

It did produce the best accuracy of any powder with 50 grain and 75 gain hornady hpbt bullets. the 50 grain load tops out at 3100 and some change, from a 20" barrel. but IMR 8208 is producing over 3300 fps with the same bullet but no where near the accuracy but still acceptable to me for my application. I may end up using it with 75's but none of my ladder loads to test were loaded as hot as I wanted. I think there is more in the tank with the 75's

trying to find a powder that pushes light bullets as fast as anything AND heavy... well I ain't got words really....

Its just not in the cards basically.

Everything you do is a compromise if thats what you want it to be, OR you load for the bullets you will use most.

Like texas hog stated, 24gr. just about fills the case. 25 grain is the most I could get in a case and seat a bullet. Their are better powders for lighter bullets.

Yep, its the same in many cartridges, regardless of the fill percentage, you generally are not using the same powder for 110s in 30-06 as you do with 210s in 30-06...

You COULD< but you won't get best performance out of either, or at a minimum generally only one.

If you did, there would be like 5 powders on the market period...

I am reworking my loads to reduce the variety of handloading components I use. After a lot of reading, I am basing a lot of that load redevelopment on using Varget.

For primers, I'm zeroing in on CCI.

My key criterion is availability in my locale.
