RE: Slowest STW known to man
I had the same problem with mine. You need to carefully bump up the powder on the STW. The maufactures are waaaaaay too conservative. I own a Sako 75 and was getting anemic velocities with mine. A fellow on another forum had the same problem until he bumped it up a full grain and 1/2.......then 3300+ was achieved instantly. I did the same with mine, and there are no pressure signs at all....none nada. I had to quit before deer season, however, when the weather gets better, I'll be doing some futher testing.....the bottom line is this.....7mm STW published loads are so conservative it isn't even funny.....it's pathetic! I have narrowed my powders to RL22 and IMR 4831.....this story is far from over. The factory Federal premium 150 grainers chronied at 3280 in my sako......wonder what they are using? Not Hodgdon data that's for sure!!! PM me for other findings. Regards, Rick.
