A good friend and customer who is not on-line was in the store last night to pick my brain. He is buying a 1893 Winchester that was refinished years ago, ruining it's collectors value. He is wanting to use it for NCOWS where it is legal. The question is, he has also found some English 2 1/2 inch shells that are Nitro, but are listed at 3 Ton PSI, I'm guessing this is "Long Ton" which would be 7500 PSi. The question is if this is OK for the 1893? He wants to start reloading and maybe swithing over to BP in the future, but for now any one have any knowledgable ideas on this. My thought are yes, maybe, but with a slight doubt.
