In an effort to get my Savage 110FLCP 25/06 Copper Fouling problem solved I thought I'd give this system developed by David Tubb a shot before I just pull this barrel off and order a custom barrel. The kit consist of 5 sets of 10 bullets with different abrasives applied to each set.If you don't reload,they also offer loaded ammo in most common calibers. I followed the directions and loaded all 5 sets of bullets,these were 117gr/.257 caliber,and this rifle so far hasn't liked 117gr bullets at all at the range so maybe these will help. Now this is a TIME consuming project.Shoot the first set of bullets,completely clean the barrel.Shoot another set,completely clean barrel. So on,and so on,until your finally done! Since I work long hours,and only have a couple hours of daylight left when I get home,it has taken me about 2 weeks to do this.
