I've tried them in both 30-06 and 30-30. The 30-30s were shot from a Marlin 336, and a Contender. With the marlin it scattered in a ten inch circle at 100 yards. Could not get any better. With the Contender with a 10 inch barrel, they were scattered all over a 12 inch target at 50 yards. The few that hit the bullseye were accidents I believe. I wish someone could make them that were accurate.
Say a .22 cal bullet for use in a .338 Win Mag. That way I could shoot foxes and wolves while moose hunting.
