Either powder will work, just make sure you have bullets that will with stand the velocity simply put. I like using the 225 grain bullet the most in my wildcat .338/300-Ultra mag.
Powder: RL-22, you can start out at 88 grains and MAX LOAD is at 93 grains of powder....Velocity being 3230fps.
Bullet is a Nosler Accubond, 200 grain weight.
