Did i hear someone call my name?
80 grains 2f pyrodex with the 295gr Powerbelt Aerotip or hollow point. Sighted dead on @ 100 yards, you'll be about 7 to 8" low at 150 yards.
See my forum to learn how to properly shoot the Powerbelt bullet. Lots of bullet testing.
If you want to use the 100gr charge use the 270gr Platinum and for 150gr charges use the 300 or 338. Keep in mind that 150 grains is meant for Long distance shooting. Its a waste of powder in my opinion and will only cause uncomfortable recoil and flinching.
Just to show you, this is what to expect with a 295gr Aerotip @ 100 yards and the 80gr pyrodex rs charge,
