So my add-to-cart finger is getting very twitchy wanting to buy the AR Stoner upper that Midway USA is offering, but I can't quite commit yet. For one, I question the quality of a $100 barrel/$450 complete upper. My second hold back is brass life and reloading.

I have never reloaded a cartridge with a rebated rim. I guess I was wondering if you have to worry about crushing it down after it has been reloaded and the brass worked a few times? I realize brass life will be shorter in the gas gun anyway, just looking for others experiences with similar shaped cartridges.

If it performs like they claim, the Predator Max 22-250 may get put on prairie dog duty only.
