Any thing unique about feeding, reloading or anything? Do you buy brass or form ?
It's the only pistol round I've handloaded for, and my experience has been incredibly free of issues. It feeds incredibly well, by virtue of its bottleneck design. Just like .357 SIG, but
without the issues involving the short neck / poor neck tension / bullet ogive going below the case lips (look up issues involving handloading for the .357 SIG).
And, oh, it's considered a "wildcat!"
You need (rather, I use...):
1. Starline 10mm Auto Brass
2. Hornady's HAP .355" 125gr (this is a
tight, accurate bullet - probably generates higher pressures - most others are sized 0.354") or Precision Delta's 124gr 9mm
3. Dillon Precision 9x25mm Carbide Dies
4. 9mm Expander Mandrel for .357 SIG
5. A "Custom" Barrel of sorts
Size (...form, actually - but in this case it's one and the same!) the brass as you would any rifle round. With the residual polish from Starline, and the smooth carbide finish on the dies, you don't really need any lubricant (but I use some form of Teflon Spray - Hornady's One Shot or Liquid Wrench). Your barrel serves as the case gauge. Glock barrels are so minimalist, that when you stand it up muzzle down, all you need to do is drop the round in - the rear hood is where the breech face should be. To check for proper sizing,
balance a flat, rigid, metal ruler on the rear of the hood, and make sure no light passes through the gap between the ruler and the case head. If I recall correctly, Glock magazines accommodated an OAL of 1.27".
Caveat: I formed my brass on a single - stage press, so I knew my brass came out exactly the way I wanted each time... A progressive may be more finicky, of which I have no experience with.
Best powders are probably Hodgdon's Longshot (LOUDshot) or IMR's 800x. I won't go beyond 10gr of the former. As a matter of fact... I'd probably go between 9.0 and 9.5gr for my pistol (Glock 40 MOS, 6" Bar - Sto barrel).
Proceed with caution! This is a high pressure cartridge, and case lips are said to split by the 4th loading.
The chance of a Kaboom! is very real... I disavow myself of any responsibility should you encounter any mishaps from the above!!! :lolz:
I was paranoid enough to wear my Kevlar shooting gloves when I first tried it out (fairly experienced with rifle handloads, this was my first attempt for pistols).
