I was shooting some Winchester 180 gr. Powerpoints althernating between a .308 and 30-06. Was doing a run with the 06, single loading from the box with a very decent groupxs considering some older factory ammo. I wish I could have seen the look on my face when I picked up the brass. I'd shot two rounds of that .308 brass and the group was just great. Three rounds of 06 and two of .308 in a groups slightly over an inch. No problems whatsoever. Guess I must have had myhead in it's usual resting place. whistle

Similar thing happened to me but I didn't do it. I was shooting my 30-06 and my .308 and my buddy grabbed a .308 cartridge, chambered it in the 30-06, and fired it. It hit the target but it was off. The first clue was the bolt was very hard to open. The .308 case came out fireformed to the 30-06 chamber.

I still give him crap about it. smile
