Has anyone had experience smithing a P14 rifle action. I was given a P14 action that has been sporterized and I want to barrel and chamber for a magnum round, e.g., 300 WIN Mag. Years ago I attempted to chamber a P14 in 30-06 and I failed because the cartridge did not feed properly. I did not have feeding problems when building a 338-06 on a Model 1917 action because this action was originally built for a 30-06 where as the P14 was built for a 303.
I am in hopes that someone on this forum has chambered the P14 in a rimless magnum cartridge with no feeding issues. If so, I would appreciate you sharing your knowledge.
