[QUOTE="nkyshooter, post: 2214689, member: 83787"] THAT slow is not "just" a slow barrel ... THAT slow is probably a bad chamber job causing pressures WAY earlier than you should be experiencing. I shoot 260AI - my favorite "all around" rifle - I built it as a 'tactical hunter' and use it exactly as you describe - hunting/chucks/steel - it is my 2nd most accurate rifle after my 6mmBR - not really a fair comparison as the 260AI is a medium weight contour and the BR is a heavy varmint. I get 2900+ (27" bbl) with berger 140 hunting vld's into about .4" 5 shot groups a 100 using (don't judge me) H414 and CCI BR4 in lapua brass (fireformed 260). There is more speed available with other powders but I don't need to go there so I shoot what I have that works. I liked the suggestion to use the Tubbs solution - that can help to clean up a less than ideal factory washboard barrel ... but that much velocity lost almost has to be due to a wonky chamber. If it was mine, and I were thinking to go 260AI or Terminator (essentially just an AI with a bit gentler shoulder angle) anyway, I might just have the barrel re-chambered to the AI or Terminator and then use the Tubb system on the barrel while fireforming the brass to the new (and hopefully correct) chamber/cartridge. Otherwise - new barrel - 260 vs 260AI vs 260 Terminator ... pick what you like/want - they all shoot AWESOME with the AI having the highest POTENTIAL velocity and the Terminator being a bit less finicky on the feeding.
