Yeah, good point. I know that shooting a hot barrel isnt good for the gun. I was letting it cool between groups, but by the time that I was done and getting frustrated I kinda said F it. Anyways, this next batch of bullets I am paying closer attention to detail and making sure that they are all seated and crimped all the same and I will see if that helps. I am sure that it will. I am also thinking about getting a peep site for the gun, since the open buckhorns sites leave little to be disired.
