best powder for 260 Ar10 load

[nutter89]

Was wondering on everyone's favorite load for a 260 out of a AR. Trying to push as close as I can to 2900fps out of a 22" 1-8.5 twist bartlein barrel. This is without tearing to much brass up and with the powder the way it is im not wanting to tinker and try and track down powder. I'll be Running 123 Amax bullet in 7-08 win brass with a BR2 primer. My buddy tried reloader 15 only got 2600's out of it.

Any help will be appreciated

My favorite load out of my dpms has been 47 grains of h4350 with 107 matchkings at 3200 fps. I also use 142 matchkings but the 107s are for coyotes.

You running a 22" barrel? And are you flattening primers?

Its a 24 inch barrel and i dont have a problem with flat primers just a little ejector mark from to much gas. I tried factory ammo from corbon with lapua brass and sierra 142s and it left the same mark but it doesnt bother me that much. I could switch to adjustable gas block but i like the reliability. And i shoot so many different loads i dont want to fuc with adjusting it all the time. I just loaded up some hornady 95 grainers but i dont think the 1/8.5 twist will like em much but you dont know until you try.

Thanks for the info Paulyr450 my go to load will be the Amax 123s I may try some 130s at some point. But I figure if your pushing 3200 out of a 24 I should be good with a 22 hope to be at 2900 but 3000 would be a + :/
