I notice that the case length is longer than the bottom of the shoulder on the .223 case. You have to open up the case to achieve this obviously. I recently got a .300-221 die for my Dillon trimmer and now making cases is easy in one step to collapse the shoulder and trim. It does take another step to deprime since the trimmer dosen't have a stem, but I prefer having a primer in when I tumble to keep crap out of the pocket. This is much faster and easier than opening .221 Fireball like I used to do. This is a potent .30 you have in a light efficient package, very cool. Half the powder of a .308 and most the punch. Any feeding problems? Have you tried P-Mags or Beta mags?
