Huvius,

Trail Boss powder is very voluminous, just drop it in, seat you CAST bullet and shot.

My Ruger 1-H .458 WM prints 1" groups at 50 yards with 460 grain hard cast wide flat nose Cast Performance bullets with 19 grains of Trail Boss. Velocity is @1000 fsp.

Max point blank range is 105 yards with a muzzle energy of 1000 ft/lbs. Optimal game weight is 230 lbs. out to 100 yards.

I'm trying to get hold of some 530 grain high BC match lead bullets for long range testing.

This is not like that SR powder, pressure is very low.
