The 380gr GS-Custom rounds as loaded fitted into the magazine. Rounds were crimped to a 1/8 turn worth of crimp applied with a Hornady seating die. Do not use any of these reloads in your 416 Ruger if they are not crimped. The recoil will knock the bullet back into the case.

This round feeds as long as there are only 2 rounds in the magazine. It seems that the pressure of the magazine spring with 3 rounds in it, when closing the bolt, pushes the nose of the top-most bullet too far past the bore axis, and it will not feed. Two rounds in the magazine work fine. It needs to be determined if a competent 'smith can sort this out, because I think these bullets are ideal for open-sight hunting with the caliber.

Pressure differences between all the rounds was not obvious from examining the primers, and all rounds extracted easily.
