Badger,

A hearty welcome to NE.com! Thanks for joining in. You've been lurking long enough with a registration date of April '08!

Here's my suggestion to your reloading problem: RCBS offers a 12ga. reloading die set, which is listed in Huntington's catalog. I don't see it on their website, but here's a scan from Huntington's 2009 dealer catalog.

Now I have a couple of questions for you. What size ball will you use in your magtech brass? How does it relate to the groove diameter of your Greener? What load do you intend to use?

Another question: What are you spending for your MagTech brass? It's pretty cheap here. Huntington sells it for less than $1.00 each.

In short, give some detail of your rifle and what you plan to shoot in it. Thought you would get off easy, eh?

Again, welcome to NE.com
