BigBill - there are dilemmas and there are dilemmas, but trying to figgure out which of those 7.62x25s to pack around and shoot is a biggie. Glad I don't have to worry about that (lol).
After you have finished shooting, if you decide you want to carry one of those 7.62s, check with Reed's Ammo - he is a sponsor on one of these sights - they ahve just developed commercial reloadings for the 7.62x25mm with soft nosed slugs, and they move out pretty darn quickly. Might be interesting to see what a soft nose does in that caliber. HTH. Mikey.
