P,

What cartridge, impact velocity and game etc have you been shooting when using the 215 SGKs that weren't opening?

I'm assuming you're talking about the .338 cal version?


Could be the 215 was designed for 338 Win Mag speeds since that's clearly a far more popular 338 than the Federal. I don't see that as a failure of Sierra engineering. Increased speed and rpm's still count with some designs.



The 280 Remington is overbore.

The 7 Rem Mag is over bore.
