Sorry it took so long to get back on here. It only took about 2 weeks from the time I sent it in to having it back in my hands. From S&W witch was great. They replaced the barrel and it shoots great. They did not say what the problem was with the barrel.
I've tried cci standard velocity cci mini mag 36 and40 gr. Federal auto match, eley sport. I have about 1500 rounds through it and has been cleaned 3 or 4 times. From chamber out only. Thanks for all your suggestions. Going to the range tomorrow if not any better I guess it's off to S&W
Hi new to the group. I have had this gun about three years. Was able to shoot 1 inch groups at 50 yards. Fairly contestant. When about a week ago it started going all over the place. Got home checked the barrel nut at 20 inch pounds its ok scope ring clamps to 20 inch pounds and 15 on the caps...
