Thread: Same load increased velocity 🤔

Amount of bolt thrust can have no discernable effect on muzzle velocity. The case / bolt are not moving backwards in any "equal & opposite" reaction, only the entire rifle is moving back.

That said, a thought on equal and opposite reactions.. if you support an all-metal rifle against a solid immovable back-stop (not even a soft recoil pad) vs a human shoulder, will the MV be significantly higher and/or more consistent from backstop-supported shots?
