Precision Reloading has Rem 10ga for 44.95/100. Not cheap, but I've used them for years.
Go here https://www.precisionreloading.com/ I've never used a lub on my resizing ring, and think it would take quite a bit to wear it out. You can see if the punch is set too low and bowing the shell with a simple straight edge. Good luck.

I bought a used 10ga Versamec several years ago. My resizing ring was worn out. The loader was set up for 3.5" shells when I got it, nobody reloads a lot of 3.5" 10ga. I load 300 to 500 short ten shells a year. The steel head hulls, Remington and Winchester, are hard on them. Only a couple of thousands of wear on it can cause problems. Resizing rings are cheap. With the new ring I see a lot of shiny brass on the heads of shells I am loading, before I did not. Shells sized with the new ring will chamber in my Remington and Lefever 10 bores where before they would not close if they had been fired in my Parker.

I load for 10ga Parker and 10ga LC Smith. The Remington rim diameter is larger by about .010" versus the Federal hulls. I have found the Smith's will not close on the Remington shells because the recessed rim in the Smith chamber is cut to a smaller diameter versus my Parker. So I can use Federals or Remingtons in my Parker but only Federal in my Smith's. After many years of loading for 10ga I find the Federal hulls more durable especially at the mouth of the hull.

Paul,

I agree that it would take quite a bit to wear out a resizing ring but with hulls that give you problems and even with the hulls using steel, a spray of lube like One-Shot up inside the ring makes them as smooth as butter, and one can tell the difference for quite a few hulls before doing it again. I just tried it again to see the difference on a sizer using a ring, and it is like night and day in the smoothness during resizing, especially on the upstroke when the shell is ejected. If you use it on rifle brass cases in carbide dies, then it makes sense to me when it is steel on steel. Just a helpful tip I thought with problem shells.

My automatic guns shooting the Cheddites (Hevi-Metal shells) dent the metal heads as if they were run over by a car, since they are paper-thin.

Not my words. "MEC Resize Ring for 600JR

The resize ring is a wear item located on the depriming station of the MEC 600 Junior reloaders. After repeated use, this part will wear and break or it may not fully resize hulls down to proper specs. For best resizing performance, this part should be replaced every so often, depending upon your reloading volume. If you are having trouble with resizing your hulls, you may want to use the MEC SuperSizer. This is a terrific alternative to the 600JR’s resize ring."

It's a six dollar part, if you are having trouble with guns not closing on reloaded shells and you don't have a MEC Super Sizer or Size Master it could be an inexpensive solution to the problem. As I said before I was surprised that mine was worn, but again we are talking a couple thousandths that can make a difference.

Gentlemen:
Here are the SAAMI shotshell specs. Page 17 for 10-bore. If the chamber or resize ring involved are off, then it may prove enlightening.

Alternatively, a switch to Federal cases will obviate any problems.

Federal 10ga hulls are the best, at the present time where have you found them available for purchase?

Pete, et al:
Those that I've used I found at Ballistic Products. They currently seem to have them in stock:

federal 10's ?? ballistic is almost always out of stock- you have to keep checking and grab them when you can


OR - make friends with a bunch of goose hunters - and get them once fired

They must have got some in and then sold out in the last hour.
