Question for you experts out there. Warning: beginner here.
I’ve wanted an MRAD in 300NM, but I simply don’t know enough when it comes to twist rate, SG, etc. The MRAD appears to offer a 1/8 twist, and I’m a little worried about that.
Using the Berger stability calculator: At 59 degrees at sea level I got an SG of 2.31 with the 215gr assuming 3017fps for a 26” barrel. Is that too high of an SG?
It looks like the RPMS for Berger factory 215gr ammo in a 1-8 twist 26” barrel would be approximately 3017x720/8=271,530 rpm. Is that getting too close to the 300,000 rpm rule of thumb for possible bullet failure?
I want an MRAD, but am worried about a 1/8 barrel that it comes with because of the above concerns...
