Anyone into the 10mm??

My Montana brother's EDC ranching pistol is a Glock 40. I like that longslide 10mm a lot. It even works with .40S&W ammo in a pinch. I said pinch......
Down here, for me the .45ACP will do. If I need more, the .41 magnum will do more.
I’ve heard some guys say it works well and they do it all the time. I’ve never tried it and probably won’t because I have no need to.

I do wish they made the 10mm case with small primers. Just seems unnecessary for a large primer but what do I know…

The 10mm Auto has had a checkered past with lots of fits and starts. It started out with Norma loadings that sent 200 grain bullets at 1200 FPS. Awesome performance, no doubt, but such loads broke 1911-series Colt receivers, which set the caliber back considerably. The 1006-series S&W stainless steel pistols thrived on Norma-level loads, as did its original platform, the Bren 10. The Bren looked so much like the CZ-97 pistol that I thought SURELY CZ WILL BRING OUT A 10mm ON THIS PLAFORM. But not yet.

Those Norma loads are a mite fierce, and between the Colt breakages and FBI's experience with the 10mm (which was "mixed", at best), some changes got made to the loadings. FBI's answer was a Federal load only slightly more powerful than the 40 S&W, 180 grain JHP at about 1030 FPS, known none-too-politely as the "FBI Lite 10mm".

Most ammo makers load a 180 grain bullet at 1125-1150 FPS. Winchester's Silvertip (my favorite factory load) runs a 175 grain JHP at about 1225-1250 FPS. These supposedly don't break 1911-series frames, and are my limit in the Glocks. As said above, they are a handful in that G-29. 16 of them on deck in the G-20 are very reassuring when afield, though--with 30 more in mag pouches. 46 rounds of WW STHPs in 10mm will do to ride the river with.

One thing the 10mm Auto is NOT--it is not a magazine-fed 41 Magnum, nor is it "No better than the 357 Magnum". It rides in the middle between those two calibers. That's not bad placement at all.

The G29 has never been a "handful" for me or a few others that have shot or have there own. Im shooting "full" loads.
My "trail load" is a cast 220g HP on top of Blue Dot @ 1100 from that G20. Shoots tennis balls past 35/40 yards. (Havent shot farther)
My STD load is a MP 200 W/PP (past book loads) @ 1275 in G40, 1250 ish in G29 & 1200+ in G29.

100% on Colts Frames cracking!
But FBI "issues" is simply pansies, limp wristers, not a caliber problem or issue at all. Women largely had issue with the 10's recoil impulse. How can one blame a caliber for being more powerful than a untrained person can handle? Most had same issue with 12ga!! Did ya see 410's issued??? As with anything training, PROPER TRAINING, not the laughable annual requirements of most departments and Govt. agencies is what was required.

Uff dah! Tell us how you really feel. Proper training. What agency could possibly have the financial or paid time available to train their officers/agents to become black belt martial artists? Then maintain that level of training. Because that is what you and a lot of gun guys seem to think about cops and guns. To shoot the number of rounds you do and develop a recoil tolerance just is not realistic. Flinching is a real thing, exacerbated by hard kicking and loud firearms. Not a lily livered immoral weakness afflicting females, children, and the elderly.

My bitch about DAAT, Defensive Arrest And Tactics training was that some lawyer, (who got the drizzling diarrhea just thinking about officer liabilty

Your speaking of extremes my friend. ALL OFFICERS & AGENTS receive a level of training. Weather its firearms or Law or administrative. It is done because its required to be done. Previous experience dictates. Penny pinchers fudge everything up.
Doing less, them crying foul is the fault of the administration NOT the items tools used. Period.

Habits are formed with in 30 days of repetition.

Flinching is a learned response.

Piss poor preformance is the result of piss poor training.

None but one was born all knowing.

Thats what Im saying. Not a decade of training to receive a black belt.

Im gonna stop tonight after therapy and see if a local shop has one of these MP 10's. I want to wait a while and be sure its better then the first first gen M&P pistols.

Couple weeks ago I decided to just go back to a reflex site on my G20. The G29 had night sites and the G40 is a MOS so it has a Vortex Reflex. The G20 was cut for a RMR some ten years back. It was before it was as common as today and the guy fit it to my site. So it cradles the optic and only has to bosses to increase thread for mounting screws. Recoil sholder is edges of site not pins. SO, Im limited to a trijicon optic foot print. Luckly a few makers (cheaper then Trijicon) offer good optics.
My biggest reason was problem getting a proper regulated site set. Three sets all labeled G20 shot low. I had a supressor set that I was ready to cut front when I remembered I had a adj factory rear. I prefer metal, But I more prefer proper regulated sites. Times crossed I was offered a deal on a used SRO Trigicon from a friends cousin or uncle... Anyhow it was a good deal and I jumped in it. Only it was gonna be after Thanksgiving as site was "home" and he was here vacation for holidays. Well the optic arrived today! It fit like a glove!! BUT, no mounting screws that fit my thread!!!! I lucked into a set miss matched length but proper thread. I cut them to length and installed the optic!

It works fine and looks good!

CW, I thought I deleted my rant but I see I accidentally posted it instead. At least only part of it made it out.

Well I pulled all these bullets...

What I found was the 10th adjuster on my scale would get hung slightly @ the "0" setting. Being as my charges started about 7 I didnt use the largest adjustments. Well it was "hung" so didnt make "0" even tho it looked as if it was.

This is a NEW scale as of 5-6 years ago. Its a RCBS 10-10 and there is a few burr's that has now been removed. Machining of the "teeth" or "notches" was not cleanly done.

What this did was add almost a grain all settings. :oops::oops::oops: SO 7.3 was closer to 8.5. I had run to 8.3 @ 1.250. This was seated to 1.205....

Mystery solved. As usual it was the re loaders fault.

But good useful information gleaned just the same. Power Pistol is not at all like my previous favorite 10mm powders. 800x & Blue Dot. Both of these have tenths from good preforming load and one thats just over the top too hot. PP was 1.5+ grains over top recommended loading yet still never bulged a case. Also my fear of being able to reach my goal within safe pressures was and will be easily accomplished. Seems OAL is less volatile as it can be with other powders.

Thanks to God you realized something was amiss.
This past time north I was loading some 450 Bushmaster. When I did my visual check I noticed two rounds high and one very low. I had half missed the mouth of one case and the other nearby two got some of the runoff into them.
Stuff just happens off and on.
