I've been looking for suitable J-words to feed my .256 Win Mag Marlin with little luck. But I think I still have a couple thousand factory .251 j-words intended for .25 ACP. How much of a chore would it be to bump those up to .257? As I recall, they have pretty thick looking jackets! I've never done any swaging other than cases. Are there machinists here that could make such a die?
THere are guys here who could do it, but would it be worth the money? Swage dies are expensive. Best thing would be to trade for .257 bullets, second best may be to sell those, then buy bullets for your 356.
