Home Forums Hunting & Shooting Ask The Gunwriters Winchester StaBall 6.5

I've been testing it in 6.5 Creed, and 270 Win. Very small groups, and single digit SD numbers all around. Very, very consistently accurate loads, all the way from start to about 1.5-2 grains over book max. Not a velocity king like R26 or R17, but much better groups in those 2 guns. Both shot well under 1/2" at 100 yards. Definitely going to try it in my .338 WM next.
