So, the round wouldn't fully chamber, the bolt wasn't rotated in place and the "design" prevented the firing pin from striking the primer. That is good because you don't want the round going off on an open bolt.

Buy a Sheridan "cutaway" case gauge. It will show you the error of your ways.

BTW...this is my favorite 300BLK projectile.

Also..1.35 trim is pretty short...I only trim mine to 1.358
