So i came across a deal on alot of factory loaded 303 ammo from FC and R-P. I got it to form the brass to 30-40 krag. For the heck of it I chambered a round in the gun and it closed perfectly. Now i know the 303 is actually.311. Could i fire this ammo in this gun and fire form all the brass?
didn't realize the pressures in the 303 where that much higher. Was thinking that they were both lower pressures due to old design and thought that maybe newer barrels like the H&R would handle it. Thanks
Could you pull the bullet and dump the powder, then resize the 303 neck, charge with an appropriate powder load and seat a .308 bullet long to hold the case against the breech and then fire form the brass?
