I have been working up a new .260 gas gun and have been getting odd behavior wherein it will make quite a decent group and then a substantial flyer. I have noticed that my case rims are bent from previous hot loads in this gun, and seem to remember that would cause flyers.
Figured I'd check in here since it has been a few years since I shot much semi 260. Thoughts?
