1st of all - check this out http://www.leitner-wise.com/lw782sx24.html
looks like a 10mm or 45 case necked to 30 cal.
(their site was down sat. am - keep checking them)
2nd of all - instead of having a custom barrel made for your first prototype - why not get a cheap POS CZ 52 chambered in 7.62x25mm?
load it up with saboted 22's (i think theyd have to be short bullets - a 55-62 grain .224 is looong!!!)
and blast away
I think you could buy a complete CZ52 for less than the cost of one custom barrel for your Glock
you might know someone who already has one.
you might not even need the sabots & 22 bullets - according to Chuck Karwan - the 7.62x25mm already knifes thru level 3A Kevlar like it is butter - a high speed 30 cal might be just the ticket
How bout a 7.62x25mm barrel for the G20?
will a 7.62x25mm cartridge fit in a G20 magazine? COAL on the 7.62 is 1.36" - Rim dia is 0.390" COAL on the 10mm is 1.26" - Rim dia is 0.424"
my G20 mag will barely hold in an empty mauser case - the lips are tight enuf.
dont know about the length though
if it could be done - 7.62 Mauser ammo is available pretty cheaply, and with a 22 sabot would be fun to play with
