Forgot to add that The Gun Works/Muzzleloading Emporium has all gauges Magtech in stock. One of note is they have 16 gauge on special for $30 a box. I bought a few boxes to have around. I will use them if I work up BP loads in 16.

art smokeless powder works good too....keep pressure on the wads when hot glueing them down on top wad...and real tight wads are nessary on black and smokeless...I use a little black powder about a 1/2 grain over the primer for the smokeless no duds this way....charlie

I just saw some ideas for 410 brass . I’d heard in the past before about using 444 Marlin brass for 2 1/2” and I just recently saw a guy say he uses 9.3x74R brass for 410 3” . It’s a thought but I’d suggest before buying the stuff I’d google the heck out of it .

They have had that posted on their website for many years.

Rocky Mt was a regular supplier to single shot rifle shooters. I used them breech seating 32/40 & 38/55. Cases turned from bar stock, RMC would make about anything straight wall. They perform different than drawn cases. Expand don’t spring back much. They were inconsistent too, due to various grades brass used.

Owners sold the business some time ago & suspect new owners are selling inventory.

I mentioned the other day somewhere that the only thing different about a large pistol and a large rifle primer is a few thousanths in length. I have used a primer pocket conditioner reamer in large rifle size to condition all the magtech cases I have used. They really need it along with a hit with a bevel reamer to make them load easier. With that I can use a large or magnum primer, and never any duds.
