Sometimes we get lucky!
I'd been shooting the Rem 300gr SJHP .458 with the orange sabots with decent results (3/4 ") groups @ 50 yards, using 50gr of 3f, T7.
Today, before the rain hit, I needed to burn some powder. So... from my lonely Triumph (tough having only one front loader), I shot this target...
1 - my last pre-measured 50 gr charge of T7, 3F. Black line though it, @ 50 yards.
2-4 - 60 gr of 2F Goex @ 50 yards
5-7 - 60 " " " @ 100 yards
that's it 7 shots... I'm scared to change anything.
I realize these are light loads, but a heck of a lot of fun to shoot!
