Im sure this has beaten to death already... But I have done about everything i can think of about my cold bore shot. many changes have been made to my gun with not much change... (CZ 452 Scout, .22lr) My cold bore shot used to be all over the place. Now after all the things i have done to my rifle over the last six months... stock, trigger kit, bedded action. tried different cleaning techniques. I am now down to this... My cold bore is half a mil high at 25 yards. If I let the gun sit for just a few min the first shot is half a mil high.... and the rest of the shots are spot on! WTF! any input would be appreciated.
