Thread: 308 out of a 303

I should try this as Ive got a pretty tight barrel which should fire 308 just fine.
Might be good for plinking and be kinder to the barrel.

Works fine in the 303 too with a few grains of shotgun powder. Round ball loading was common in the past for many cartridges. I occasionally still load 45/70 that way.
