I know 6mmbr is more of a precision shooting kind of place and my question pertains to a deer rifle but I figured I would get some good info here.
I have a 1956 vintage Winchester model 70 in 30-06. I shot some Federal 150 grain ammo and some Winchester 150 grain ammo through it. I wanted to reload the brass for the Model 70 and for highpower in my M1 so I tumbled, polished, sized trimmed and all that. When I was getting ready to actually put powder and a bullet in the brass I noticed a slight bulge at the bottom of the case. If any one is familiar with the bulge you get with 40 S&W the bulge on the 30-06 brass is pretty similar.
It looks like all the brass shot out of that rifle has that little bulge. If you have a nice clean case and hold it under a desk lamp and turn the brass in your hand you can see the case is just slightly deformed mostly on one side or about a third the way around just above or right even with the web.
My question is: what the heck would cause that?
I have no signs of over pressure. The rifle came to me used but looks like it has not been shot very much. I get about an inch and a quarter or so groups with it.
I really wanted to reload the brass that went through that rifle but I’m afraid if I reload brass with a bulge in it the brass has already been weakened and If I make up a nice concentric round as soon as I stuff one in the chamber the round will be out of alignment.
Any suggestions?
