Making a 30-30 Small Base Die

[FredBuddy]

I had the same problem as the OP.
My brother gave me a pile of once fired brass
from his rifle and its oversized chamber.
Sized in my RCBS die, fits in all but one of
my 6 30-30's.
Fortunately I also have a Redding die set,
and that sizing die is tighter and solved the
problem for #6.
Lots of good suggestions in this thread,
especially the 40 S&W idea.
I know, 30-30 brass is cheap, but what
happens when it ain't......................

If you have a lathe you can spin polish the heck out of the die with the vent hole problem until it works without scratching your brass.

I have some 30-30 brass that was fired in a real sloppy chamber. It has a ring at the base that my die doesn't size the base down quite far enough. It will chamber but is snug.

Well I have a spare die body that leaves a mark on the brass at the vent hole. Been thinking I could cut the die off on the top just below the shoulder area, and then grind odd about .010 from the bottom so that I could get that brass sized down more at the base.

It would of course size the body a little more, but I don't see a problem as I'm only going to use it for the brass as needed and not every time.

Anyone have ideas or advice for me?

Thanks

Thanks EDG for the suggestion. I've tried several times to polish it. I don't have a lathe but I reversed the decapping stem and used that to spin it in a drill. I spun it both ways and polished with 1000 grit paper on a dowel. It makes a little raised bump where the vent hole is. It is in the center of the shoulder. The other dies I have with vent holes have the hole lower on the die right at the junction between body and shoulder.
