3" 410 brass shells

Falling down the rabbit hole the other day, I found a source for 410 brass shotgun cases for reloading. I already load regular 2 1/2 and 3" plastic hulls as well as 444 cases.

The company is Rocky Mountain Cartridge and they do ship the brass cases to Canada. They're not cheap, machined from solid brass rods. As I understand, the inside diameter of the hull matches plastic cases so wads work and the cases take 209 primers.

FIrstly, I wondered if anyone here uses them? They are also available in a ton of other gauges and lengths.

If anyone has them, would you part with a couple?

If no one has any, is there any interest in splitting an order. They come in 20's @ 94USD plus at least 20USD shipping plus whatever magic the customers people decided to dust them with.

Thanks for the info. Will check it out.

Very interesting company ! Would love to have a few on display in mancave but as you pointed out they are not cheap.

With the latest shortage of .410 ammo reloading seems the way to go. I have been looking for .410 ammo without any luck. Ken

I had the good fortune to come across about two hundred once fired Remington and Winchester .410 - 3" at a gun show, I also was able to pick up a LEE Loader for 3" - .410. I made a block with a dowel in it, to set the shorter 2 1/2 case on in order to crime them. Before that I came across an article on blowing out .303 British case. It provided me with something to do with the collection of old Berdan surplus brass I had. I drilled the primer pockets out to receive 209 shotshell primer, and then thin the rim a bit to chamber in my bolt gun. I primed the case, and added 3 or 4 grains of shotgun powder, some COW filler and sealed the case mouth with wax and fired it. After that further fire forming could be achieved with a standard load recipe for a 2 1/2 .410 shell.

I am in the process of doing same with 303 and 444 brass. To help fire forming you can anneal the 303 brass but not down to the head. One problem l ran into is one of my 410's the firing pin is too short to strike primer.

The trouble with using the 303 and 444 cases is the short case length and therefore small payload. My currently manual reloading setup for the 410 plastic hulls is a hoot - The decapper is from an old winchester 32-40 reloading kit. My primer setter is a 10 gauge unit that my Grandfather had. I just found a washer that was 10 gauge outside and 410 sized hole. I use elmer's glue keep the components in the hull. It works fine.
