SGK 65 gr #1395 @ 3375 fps was not suppose to stabilize (1:12) in my TC Venture 22-250, according to JBM.
The day I shot it at 100 & 200 yards, they were going through the target making small even holes, normal grouping for me..
Will try it again to be sure..
Haven't tried 55gr #1365, but JBM says its stable(1.53) @ 3500 fps.
