RE: grand slams
Really like the RL 22 in the 270 win and 300 Win.
Butmy 7mm Mag seems to like IMR 4350 with 160gr pills.
2.5" is not bad....I zero mine 3" high for long distance shooting this usually gives a traj dead on out too 300 yards or so!
160gr is the optium bulletfor the 7mm Mag. I used alot of Sierra BT over the years. The new Accubond 160gr suppose to bevery good today.
