[QUOTE="swampratt, post: 3786463, member: 15054"] Were the reloads from Amer-I-Can ammo shot from the same DPMS rifle? Usually when brass is shot from an automatic rifle it gets much larger than when shot from a bolt rifle. Now not all brass has the same alloy. I had hundreds of rounds of LC05 7.62 and it was very hard to resize. Shot terrible groups compared to my winchester cases anyway. Bad enough I sold the few hundred I had left. I was able to test different lubes with that hard to size brass. Imperial and Hornady unique case lube. Hornady actually allowed the brass to slick through easier. Case necks were also lubed on the insides of the neck with a Qtip. Cases were brushed with a nylon bore brush before lubing and sizing. Larger than a .308 brush of course. That does help just a little bit more. I have never used any spray lube and what I read about it is it needs to dry before you size or it will be a bit harder to size cases. [/QUOTE]
