    I’m building a AR-15 in 243 WSSM 24” barrel 10 to 1 twist, I would like to shoot a 70 gr bullet at 3700 fps,
    I'm thinking 48grs of 4350 will do it, and naturally, I will work up to the max load. Love to shoot those dogs on the run at 500 plus yards. Any help
    would be greatly appreciated, it takes a lot of time to work out the best bullet and load for a gun, I’m sure you know but that’s some of the fun, any
    help.

    Mine is a DTECH and shoots near 1/2 MOA all the time. It is reliable. The only animals shot so far are pigs. It works well when shots are properly placed.
