.260 Gas Gun load info

[KS]

Hey guys,
I just ordered an AR10 in .260 from George Gardner. I want to start collecting some load data that works for others to get me in the ballpark for MY rifle.

Any help is greatly appreciated!

Thanks,Keith

Talked to George Gardner to see what he can recommend.

A gas gun requires different powders to keep things from breaking. In general, they prefer faster powders to provide a good pressure "pulse" and short duration to keep things from breaking. However, George may have designed a bleed off system or something else that would allow any suitable powder to be used.

Good luck...

IF, you find out you can use any suitable powder in your gas gun, I have had good luck with IMR 4064 and RL-19 with 120 gr. class bullets, and either H 4350 EXT or H 4831SC with 140 gr. class bullets in both of my bolt guns.
