Looking for loads to shoot from 100-300 yards.
Here is what I have:

Rifle
Savage .223 with factory 26" 1/9 twist varmint barrel.
Shoots about 1/2 MOA at 100 yards with factory Federal Match 69 grain Sierra BTHP

I have Lake City once fired brass completely worked over and primed with CCI400's ready to go.
I would like your bullet and powder type/weight recommendations. I will use common sense and start lower, just wanting to know what works for you.

Thanks!
