Yes, that’s what Sierra says, but it still doesn’t make sense. The 215 didn’t open on dry magazines at 338-06 muzzle velocity. That’s not that far away with a winmag.
Did you mean to say "didn't" open? If so, thats interesting.
Correct. Fired through chrono directly into magazines. I don’t recall velocity. Mid 2600s? Left a .338ish hole through a couple feet of dry magazines and kept going into ground further than I decided to dig. Shot a second, same result. Needless to say I decided those weren’t going to work for hunting. I sent a note to Sierra. Their response was that it was designed for a winmag. Umm, ok... If so, I guess it’s only good to ~100yds.
I realize dry magazines are not great representation of animals. Maybe fluids would have helped. But every other bullet performed in a way you’d expect. I’m pretty sure scottfromdallas tried them in milk jugs and had same result of them not opening.
