I was at the range this week and after shooting 50 rounds of Remington gold bullets in 22lr I noticed my accuracy was really off.I unloaded the gun and noticed a third of the bullet was in the last 1/8th inch of the barrel.I had shot about 2000 rounds of cci and federal automatch and never had this problem.Luckily it was a semi auto and I was able to take the barrel off and get out the lead with a dowel rod.I was worried that the accuracy would be messed up but went back the next day with automatch federals and everthing was fine.
