One observation is, the primers were slightly flatter in the Glock 40 MOS (middle pic) than in the Glock 20 (Top Pic) but by only a very little bit. Which the Glock 20 had virtually no flattening at all. The Banshee had the most flattening by a Longshot (no pun intended) (pictured bottom)
I'm not positive that this indicates a greater PSI pressure build up, but it could. Design of the gun can play a role in this, and other factors than just straight up CUP/PSI. Ain't no telling for sure. Primer reading has been proven to be junk science, but I still look at them with a grain of salt.

The Glock brass are all in excellent shape thanks to the Aftermarket Lone wolf (20) and Alpha Wolf (40) barrels which offer better chamber support than do the factory glock barrels.... there will be no "smiles" involved and these will all be reloaded again with a standard Dillon factory Resize die. No roll size/Push through required with these great barrels, even with maximum loads. Well worth the 100$ or so price tag for the extra chamber support and ability to shoot raw lead. Supposedly this can come at the cost of cycling relibility, but if you keep your ammo to spec, reliability is typically never a problem...

Data on the way shortly....

In 1 10mm carbine cases started separating. With the same case, load and bullet they were fine in the handgun. Cheap Jag brass (black). I have brass, nickel and black nickel so ammo can easily be identified. Maybe the black nickel will be less hot loads.
 
Ok, here's the 5 shot averages for each gun, for each of the 12 Loads. Again, all of these are 180 grain bullets. (Ill update extreme spreads). All primers are CCI LPP except load #4 which is WIN LPP

G20- 4.6" Lone Wolf barrel
G40- 6" Alpha Wolf barrel
BAN- 8" factory barrel (CMMG Banshee)
30 degrees farenheit

G20- 1,317 fps. G40- 1,384 fps. BAN- 1,402 fps.

#5- 9.5 gr. Longshot- Hor. HAP OAL 1.2520"
G20- 1,343 fps. G40- 1,417 fps. BAN- 1,444 fps.

#6- 11.0gr. Blue Dot - Hor XTP. OAL 1.2520"
G20- 1,373 fps. G40- 1,435 fps. BAN- 1,477 fps.

#7- 8.7 gr. Power Pistol- REM JHP OAL 1.2500"
G20- 1,295 fps. G40- 1,354fps. BAN- 1,357 fps

#8- 13.5gr. AA#9 - FED HST-JHP. OAL 1.2550"
G20- 1,238 fps. G40- 1,300 fps. BAN- 1,350 fps.

#9 - 8.0GR Power Pistol- Berry's JHP OAL 1.250"
G20- 1,118fps. G40- 1,158 fps. BAN. 1,223 fps.

#10 - 14.0GR AA#9 - Armscor FMJ OAL 1.2580
G20- 1,278 fps. G40- 1,347fps. BAN- 1,392 fps.

Factory Load #1 SIG 180gr. V- Crown JHP
Advertized Velocity: 1,250 fps.
G20- 1,198 fps. G40- 1,247 fps. BAN- 1,245fps.(scratching head, maybe they used a faster burning powder?)

Factory Load #2 Magtech 180gr JHP (10b)
Advertized Velocity: 1, 235 fps.
G20- 1,162 fps. G40- 1,235 fps. BAN- 1,269fps.
(G40 nailed that one!)

Let me do some more number crunching and put in extreme spreads....because at first glance, there are some more significant than others.

I've shot the G20 plenty. I'm no Gluck guy, but if I ever own one, it'd be the G20.

I also load my 10mms pretty spicy, and nearly all of my fired primers are flat.

If you are going to test all those loads wouldn't using the same bullet for all give a better indication of velocity and or accuracy?

Youre correct. But these are from several years of loads just brought together at once...they are what I have. Im taking a step in the right direction, I'm hoping this experiment can help me pick how to refine loads from here for each gun....
I did use the HAP bullet with both my 2 favorite powders...
 
Power pistol has done well along with 3n37. I've been partial to silhouette. I've used hs6 and be86. Blue dot for light weight bullets and packed with 118-120% charges and still under max. I stopped because I felt like I was handling nitro in liquid state.

You can use the same "loads" just use the same bullet. Otherwise there is that nagging variable.:)

The Banshee takes any 15 round glock factory mag, but those are 30 round mags made by SGM tactical. Glock doesn't make 30 round extended magazines for 10mm......yet.

Another option are the 20 round ETS 10MM magazines. I had two and they ran fine. I sold my G20 and they went with the gun.

I own and shoot more Glocks than anything else but the large frame Glocks are just too large for my stubby fingers. But that G20 was a hoot!

by default… we are all Glock guys. Ever bought a striker fire - GLOCK GUY now

The Roth-Steyr M1907, designed by Karel Krnka, and the FN 1910, designed by John Browning, were both successful striker-fired handguns predating Herr Glock's birth (1929). Glock was a late comer to the striker-fire, dropping block, locked-breech, polymer-frame parties. Good advertising and a horrible movie franchise (no one talks about Die Hard 2 except to note the errors about Glock handguns)

But, in order to know any of that, you'd have to be curios enough to find out who actually invented the striker-fired mechanism, polymer frames, and the dropping-block/locked-breech action.

JMB invented everything we ever need to know about pew pews’s
 
I'm going to jump to conclusions here.

Did the CMMG Banshee bulge the brass for any of these loads?
Click to expand...
I was going to get to this part... yes, absolutely. Most of it is bulged beyond being able to be reloaded. The entire back 1/8" of the AR style chamber in this Banshee is unsupported. This is an email I received directly from CMMG on this deal, just after I noticed it happening after I picked this gun up 3 years ago. I was unaware of this happening when doing my research on the 10mm Banshee. Let me note that none of the brass is cracked, nor are any primers blown out. This same thing happens with 9mm fired from an UZI
Screenshot_20220304-094039_Yahoo Mail.jpg
Let me note that of the 12 loads I tested, 5 loads did not bulge the brass in the Banshee, and the rest did. All of the Blue Dot (11.0)and Longshot (9.5) Loads bulged the brass near the head, as did the higher of the power Pistol Loads (9.3). BOTH factory loads tested didnt bulge the brass, nor did the light power pistol load. Nor did the AA#9 load at 13.5 grains.

Yup. I certainly could..... Again, these are the loads I had developed over the course of time, and decided to just bring them together at once. This isn't a perfectly sound experiment with perfectly fixed variables...... but I do have a few bullets on hand and the powders I'm liking the best.....

How about The Walking Dead, Season 1 Episode 1 during the road barricade, where Grimes tells the deputy pointing the Glock to take his safety off...and the officer then pushes on the side of the trigger guard on the safety thats not even there....ha.
 
I'm going to do this same experiment with 4", 6" and 8 3/8" 357 Magnums with loads I've developed over the years.....see where it compares to the 10mm. I have a hunch that the 10mm pushes the 180gr. bullets at about the same velocity the 357s do with 158gr bullets based off a general glance at the numbers.... many of these 357 loads are book max, with powders like H-110 WW-296 and Alliant Power PRO 300 MP and 158gr Jacketed bullets.
It won't be apples to apples because the different weight bullets, but I'll do energy calculations to see where they're at.

Never seen it. Not even one episode for a minute. Not my kind of thing. I like Hallmark movies. Love the happy endings and impossible chance encounters. ;)
Who doesn't like a happy ending?
