Has anyone tried resizing and trimming 30 BO brass to 30 carbine? I found a bunch of brass this morning and was thinking of trying it. Case head is 0.372 vs. 0.355 for the carbine. Not sure if that is close enough without trying.
 
if that was the case, you could just trim .223 to .30 carbine an everyone would be doing it. a 300BLK is just a .223 with the top cut off.
 
Thanks guys. Saved me the trouble. I'm not interested in trimming the rims. They looked so close to the same size when I picked them up.
