10mm shotshell

[M16]

I'm working on a 10mm shotshell. So far it works well in my 10mm revolver and loads and works well in my semi-auto. In the semi-auto it has to be single loaded as it is too long to fit in a magazine. I'll eventually cut the shot capsule down to try to get it to feed. I'm using 10mm magnum brass necked down in a .357 sig sizer die. A .38.357 Speer shot capsule loaded with no. 12 shot. The powder is W231 and I am using an over-powder wad made from a plastic water jug.

That's really cool. Thanks for sharing that with us.

I made some for the 40S&W with the 9x25 Dillon sizer and 10mm case.  I need some longer cases to do the 10mm shotshells.  I used Red Dot powder and #6 (big and less pellets) but have #9 shot for the next run...there two paper wads over the powder, packed with the shot and capped with a gas check.
