That was the first thing I thought of after seeing the picture. One of the hardest thing to get a new shooter to do is exercise patience between shots and give the barrel time to cool. I struggle with this when my son (18 years-old) is at the trigger. Normally they just want to shoot.
.243 win will heat up a barrel quickly if not given ample time to cool. Even the heavier barrels. Hot pipes do nothing good for groups. Doesn't do the throat any favor's either.
