My wife has a cousin that has a tirple duse that he bought in 1960. Since then he carried it in his pick-up. Acouple of years ago he told me that it just wasn`t accurate any more. After over 30 years in his pick-up and as many rounds as he had fired through it I thought it might be possible, but have never heard of anyone shooting out a .222. I brought the gun home and run some Sweets 7.62 through the barrel, 50 patches of it to be exact, and the last patch was as blue as the first. Since I was tired of cleaning his gun I took it out and fire test firsed it. 1/2 moa., I figured that was good enought for him, brought it back in and put a coat of finish on the stock and took it back to him. He was happy as a pig in you know what.
It`s a real good round and pretty cheap to load. I think that there are still a few bench rest records held by the .222 and they quit useing that round years ago.
