No Hi-jack here,....if you think about the simple and straightfoward way a pinned rotary bolt head design works,
( Savage 110, circa 1950s ),....with the action in battery, on a cartridge,.......the PIN takes little or no impact.

I personally LOVE the Savage 110, strong, reliable, accurate.

The PINS are not part of the breaching design, rather suplementary,.....and only for the LOCKING and UNLOCKING the action phase.

If the pins discussed were prone to shear from simple locking / unlocking,......something's really rotten in Denmark.

Let the chips fall where they may.
