DIE SELECTION FOR RELOADING FOR MY M1 CARBINE.....HELP NEEDED

[M94/14]

"Lee carbide dies are contour ground to provide step-less sizing. After sizing a case, except for the burnish, you cannot tell where the sizer stopped. Other brands leave a pronounced step where the die stops."

If wanting to use a die set with a carbide sizer, this is important, at least to me.

Unless the RCBS sizer is also "Contour" ground, which in this case means that the carbide sizing insert is ground to the same taper angle as the case, then I would go with the Lee sizer. The .30 carbine cases need very little expanding if seating jacketed bullets.

Pay special attention to case length with the carbine brass, they grow alot when sized.

I don't taper crimp mine, I just adjust the seating die carefully so that it just removes the slight bellmouth in the case as the bullet approaches full seating depth. This is easy to accomplish, but may take a few "dry" runs to get there. Using this method I have never had bullet "set back" during loading or firing, the carbine bullets have a long bearing surface so they stick into the cases very well.

Yes they do. Wide chambers can make this more than less too.
