Has anyone ever heard of pouring acetone down the barrel, then, Dry patching to get Clean Cold First shot accuracy? OR, do it, then fire 1 or 2 fowling shots to get later Semi-Clean Cold First shot accuracy while Hunting? OR, use Ronson Lighter fluid instead? I had a problem after I worked up my one 338WM load 225gr MRX 3,000fps with Clean Cold First shot accuracy. Just learned last month that she likes 185gr GMX Superformance with dirty barrel-10 to 15 rounds then tightens up???? Go figure! Tried five other peoples process of cleaning after shooting and Nellie did not like any, including mine!!! Which would remove the most Lub and be barrel safe for a week of ELK hunting, acetone or Ronson lighter fluid ????? I'm going to try it in OCT., for my NOV. hunt.
