Those old triple duces are still hard to beat. My wife has a cousin that bought one in 1960. Since then he has carried it in his pick-up truck. Acouple of years ago I ask his how many groundhogs he had and he said his gun did shot accurate any more. It was an old 722 Rem. and looked warn out for sure, but I brought it home to clean it up and check it out. After 50 patches of Sweets 7.62 the last patch was as blue as the first. Being tired of cleaning I took it out and fired a group. I fired it at 80 yrds., cause that`s what was handy, and the group looked alot like yours without eather flier. So I put a coat of finish on his gun and took it back to his. I figure that I`ll clean the rest of the copper out in another 40 years. Got to love those .222`s.
