Eventually I may get a 10mm to try out a Glock (G40 I think) - Friend has one, haven't fired it yet. Usually a 1911 user.
To make the usual odd thing I'm working on, eventual project, I'd want to make shot shells that fit it. 10mm is based on the .30 Rem so I have looked for that but only can find loaded rounds for that and they're $2.16 or something each. If I have it right I maybe can modify some 30-30 brass (have to have someone with a metal lathe remove the rim and cut an ejector groove in them though...)
Anyone on here have an idea on a source for 30 Rem brass in small numbers? (Say 20 or something - Could even be brass with neck cracks so if someone shoots a LOT of 30 Rem I could use their cast offs as I'd be cutting them down to ~1/2" longer than 10mm brass, and sizing them down with maybe a 375 or 357 or so die so the front part fits inside the bore, same as 45ACP shotshells.) Not close to getting this done (still trying to get properly set up for reloading here, knees aren't helping!) but trying to plan for 6 months down the line maybe? Thanks!
