I was purusing my new Barnes reloading manual and noticed a new powder. MagPro. For my 300 Wby Mag, my pet load has been 88.5 grains of RL22 behind a 150 grain Barnes XXX. They had a load for this bullet with 96 grains of MagPro for a velocity of 3543. Wow!!!
Has anyone used this powder? Is it accurate? Consistent?
Thanks.
