Is the RCBS 11mm 370 grainer a GC design?
Title says about all there is to say.
Looking at (MSS) catalog pictures it looks like it has a GC heel.
I plan to PP it and use it or the Lyman 340 grainer in a fast twist muzzleoader.

No gas check I use one wrap of freezer paper 70 grains fff in my Green Mountain barrel
Thanks for the info dead dog. bad picture in the MSS catalog, shoulda used duckduckgo.com search first.
Guess I will be going to the 340 grain Lyman anyway since the RCBS mold does not appear to be around. Not a bad thing since it saves lead and I am sure 340 grains of lead will carry as far as I need it to and impact with authority.
Guess I will get it ordered tomorrow, cast some when I get back.
Idahoron thanks for the picture, I guess this is with your paper patch as described in your write ups. You do not use a felt wad under that boolit as I remember from reading your different write ups/youtube videos. What does it mic before you run it through the 0.446" die?
As usual I have dilly-dallied until it will be an effort to get lined up for season with this combo.
May have to go back to shooting here at the house so I have no travel time involved in a shooting session.

I do use an over powder wad. FOr my .446 I am using a wad I cut my self out of wool felt. The wads I make for this are .500 so they are a pinch too big. I like them over sized, when they go in they pucker just a bit. The paper protects the bullet from the hot gas. The over powder wad makes the load more consistent from shot to shot.
I think they are at .450 or .451 I don't remember. I really didn't care since I wanted them to be sized.
Well th whole project is on hold til the end of Sept so I will see where it goes from there.
