I don't know guys......an 8 twist barrel begs to be throated long but for it to be so long that the 75g Amax isn't even in the case? Holy Crap!

dcloco, are you thinkin' what I'm thinkin? That barrel is just beggin' for a set back and re-chamber to 223 AI

;D


2gr8dgs, instead of dropping the bullet in the chamber end......take a case and cut a slit in the neck. Start the bullet of choice in the neck and rub a little gun oil on the ogive area. Chamber round (no powder/primer) and remove slowly. That might give you a better idea of what you're dealing with.
