It's probably divine intervention Jim and I don't live

very close to one another. I truly enjoy his company on any level and he has been a wonderful mentor. Were he around close, I could envision him encouraging me, albeit from a save distance. Gary would stand an even greater distance away. lol

I am not a professional Glock'ologist. But I love to tinker and have done a whole bunch of it with the plastic frame wonders. I have a large platform G20/21 that I use and to a lesser extent, a G23/19 that I do have multiple caliber barrels (9mm, .357 SIG, and .40). The G21 has been a real fun platform and I think it would serve well for shorter range hunting as well. I have had a $125 Wolf 6" barrel in 9x25 Dillon for a while. I find them well made, nice cut conventional rifling, with a .355" bore. It was born for target shooting, to reach major power power factor within the rules with less recoil. It never caught on. I see factory ammo available from some boutique suppliers ranging from 90 gr./2,000 fps to 180 gr./1,200 fps. Not really sure what that is good for but it sounds fun. Proper Dillon specific dies cost half what the gun does, but I do have some .357 SIG dies.

I headspaced the brass to fit my specific chamber. That is better than what you'd get in a box. I used 10mm brass and the SIG dies, .356 GNR dies are too long, FWIW. Then I used a .50 BMG chamfer tool to gently prepare the necks for projectiles. The short bottle neck requires rifle techniques. No expanding the neck or it will blow the neck tension. No crimping either as it is supposed to headspace off the case mouth as well.

The 10mm auto case uses large pistol primers, I always liked that, someone was thinking. The load data is sparse but I did fine some tested and published data. Only it is for weird powders I have never heard of, BR something. I did some of my own research and calculated some "safe" loads from .357 SIG data using my old friend Unique. I cast most of my bullets but needed some jacketed for this first test. Some old 115 gr. JRN filled the bill. My "calculated" load filled the cases up to the beginning of the case shoulder, which seemed fine and self limiting.

I loaded up 25 cases for my first testing round. Wouldn't you know I only had 24 115 gr. JRN! Fumbling around I found an old self cast 175 gr. TC gas check. A fantastic bullet from my .356 GNR test bout. Recalculating a load for the heavier bullet I loaded ONE test round.

Some guys may not be able to handle this, but I've been doing it for some 45 years. Plus I find it deliriously fun and satisfying. I only share with my friends for their entertainment. I know my friend D. in CA has played with the round. I'll keep you posted.

Forgot a critical point...

With any semi-auto the "chamber case head support" is critical. The chamber must support the case fully, to the point the only part out of the chamber is solid, thick brass. This barrel has excellent support, with the entire case in the chamber, save that one little sliver which is solid as well.

I have seen some Glock barrels, even factory ones, that I'd personally consider dangerous! They probably fed fantastic but if that weak part of the case is exposed at minimum a "bulge" will manifest, at worse a case head rupture could occur, and hot gasses blast out. The KY State Police had some G21's with trouble.

We would be fine.

I have never blown a gun up accidentally. On purpose doesn't count because I was expecting it to go. And I still have all my fingers and eyes and eyebrows though my hearing is getting bad according to the few people I can understand when they talk to me .. as long as they are facing me. :-P

Many years ago I bought a 4” Colt Police Positive Special

It was a .38 Special, 6-Shot. What a wonderful balanced revolver, just right! I loaded up my favorite .38 load with 5.5 gr. Unique and a cast 158 SWC. It seemed pretty lively and hit POA to the sights where I liked.

Hornady had just come out with a new manual that I bought. (Early 1980’s) Much to my shock listed in the “new” manual my .38 load had been moved to starting .357 Magnum tables. I double checked my old book, sure thing it as a .38 load in the prior version.

I can imagine the powder formulation changing it had to be lawyers! It bothered me mentally, so I backed off half a grain. 5.0 gr. Unique 158 SWC still runs over 850 fps and is nothing to sneeze at!
