Recently got hands on an Enfield P-17(M-17 U.S. rifle, whatever). Any ideas on a decently priced source of 30.06 Springfield ammo? Should I be concerned about using modern loads in it? I had a bastardized SMLE .303 and shot hundreds of late '70s commercial loads plus some nice nickel jacketed milsurp dated 1920. Bought 100 rounds for $10.00 back in '80. Sorry, I digress. The point is I had no problems whatsoever. Can I expect the same today?
