Check around the perfect bolt may be out there, folks make a living parting them out, folks run em down till they need a part! Ive seen some rough looking jobs shoot like a house afire! You got to remember what the OLD Winchester folks ran thru em before the WP stamp went on! I seen old timers fill the case, tap it twice, pour more in, seat the bullet and bang away, I was young and dumb, now I would walk behind the truck before the hammer dropped! LOL the very best WinPoor
