I see many ejection issues posted here and many are fairly straight forward issues. Cleaning, foreign materials, ejector spring/pin/ball. But I have to wonder if some of these aren't simply caused by over heating the chamber. Expansion causing hang issues which disappear once the barrels have cooled. If this is the case. How much can be lapped away without causing other issues? I'd imagine headspace would have to checked to rule it out.

Something like this would hardly be noticed when hunting but siting, bench shooting with factory "Pencil Stick" barrels... What will these barrels take in terms of shots per round? I'd guess probably something like 3-5 shots 8-15 minutes cool-down. I'm pretty sure when my kids shoot its more like 5 down the pipe reload 5 down the pipe. Check groups. Repeat. Repeat. Repeat. Reading this sounds to me like my kids need their own rifles. At least the 13 yr old twins. The older 2, 16 & 18 are pretty well setup.

Just some random thoughts and like 3 questions buried in there. Comments?
