Re: AR COMP by Alliant
Guess not Tank. Curious myself. I've got a jug of it I'm going to test run in my 6.5 lapua. Should get my hands on the new lapua this month. You thinking of giving it a try in your 308?

I have couple pounds of AR in the mail. Waiting for it to get here. I am going to run it in my .308 and see what it does. Hopefully it will work as well or better than the RL15 I currently use.

Re: AR COMP by Alliant
I just talked to a tech at Alliant. He said the burn rate of the AR Comp is between RL15 and Varget. That tells me that the 42.4 max grain weight for a 168 is a little conservative, but will start low just to be sure. I use 43 and 45 grains of RL15 with 175's, and have used 44 to 44.5 grains of Varget with 178's. But the 44.5 did show some pressure. Anyway, just thought I would share that with you.

Re: AR COMP by Alliant
Well here are the results. Granted I found a load .4 grains over the suggested max, and I didn't get the velocity I was hoping for.... I'm not going to complain.
Load: 42.8grn AR Comp, ES 4.5, SD 2.8, Avg. 2790
Off of a bench w/ bipod and rear bag. CTC .116" in a three shot group. I feel that should I have had 5 shot it probably would still be under .25" (assuming I didn't throw one  ).

Well to put it conservatively.... THAT DON'T SUCK!
When I get set up to start loading .260's I may talk to them and see if they have any loads worked up for it.

Re: AR COMP by Alliant
I should also mention that all my loads were within 26fps as an ES with this powder. I started at 41.5gr and worked my way up to 43.5. 43.5 gave me speeds of 2882-2908fps. The groups started to open up after my first accuracy node. I didn't continue because, who can complain about what I have?  I'm most certainly not too concerned. Most of the groups were less than 1" at 100yds. I have one other group with 42.6grns that measures .361" That is with the cold bore. It is obviously the group before the keeper. I was watching them come together as the loads were changing.
