I have a 270 caliber Remington 7600 that I have owned for at least 28 years. When I was a teen it rode with me in the truck and was beat around a lot. I used to shoot a box a week through it and to be honest I didn't clean it very often. Never jammed or had a misfire. The only problem I ever had with it was that it nicked the tip of the bullet every time I put one in the chamber. This nick never seemed to cause a problem with accuracy but it always bugged me. has anyone else ever had this problem with their 7600? I have not shot this gun in about 22 years. I plan on taking it to a gunsmith to have it cleaned and lubed. Future plans are to shoot it in riflegolf and start hunting again.
