Re: New Brass, .243 Cracked neck
The pictures don't look so much like burned through holes as they do a folding of the neck brass from too much case lube. I suppose if the cases had the folds before being shot that the area around the fold may be thin and/or stretched and easily burn through. ??????? Maybe not????
A lot of people use spray on lube. I don't like it because it is too hard to control for volume on each individual case. I much prefer rolling the cases on the RCBS lubing pad using their water soluble lube. It is old fashion but it is better at getting the right amount of lube and not too much on each case. After the cases are loaded it is easy to remove the lube with a damp rag followed by a roll on a towel. This is just the way I do it. Others here have their ways too.
