I'd happily give it all away,cut my losses and move forward in a positive direction...........(hint)
It would be a boring world if we all connected those dots the same way, no?
The .257 gives the guy who is never going to shoot past 500 at game, pretty much everything he needs.
Oh I probably know the chambering well.
Bullets matter more than headstamps and there just happens to be a goodly selection of chamberings,that will do very tidy things inside the 500yd line.
Funny part is,they'll do some well beyond it too...................(hint)
