I have a Remington 700 VSF (Varmint Synthetic Fluted).223 with a 26" fluted barrel, my favorite .223 prairie dog rifle. My brother gave me a box of 500 Sierra 55gr BK bullets so I made some test loads, found one that works very well and proceeded to load 300 rounds in preparation for my next prairie dog shoot. Then the thought occurred to me. How long does a barrel last? I've probably shot 1,500 to 2,000 rounds thru this barrel and it's still very accurate__no problems. I don't load "hot"; I load for accuracy not speed. So, what are your thoughts guys? How much life can I expect from this barrel?
