Oh, in no way am I saying the 10mm is the equal to the .41RM, when both are loaded to potential.
Simply not the case at all.

original poster doesn't say 45 acp, everyone went with that to make some sense in the postings, now off to 41 mag. Since were on apples and oranges again lets compare the 41 mag to the 454, its a 45.
Most people don't have what it takes to get old

Both of Norma's loads were pressure tested at well over the SAAMI limits. Buffalo Bore isn't even a member of that industry group. Double Tap's ammo was just posted as being "overly optimistic" in their velocity claims. This particularly important with the 10 mm round. It goes critical rather easily. I found that out using some of Accurate Arm's data for their AA#2 powder. They don't list any data for it now. The other thing is that you really don't need to push the 10mm's limits to get outstanding performance with it. A good 180 gr. class bullet or a 200 gr. bullet at the general level of performnance does a very good job w/o any extra effort. E

Here I am saving money for a 1911, and of course I find a Smith 610 on sale locally. Hmmm....

One only has to visit U-Tube to realize what the penetration of a 165, 180 and 200 grain bullet will do coming out of a Glock model 20 pistol.

The hottest load I have shot with a 10mm is 14.2 gr 800X 200 gr and the primer pocket gets loose.
The hottest load I have shot with a 45 is 16.5 gr AA#5 185 gr and the primer pocket gets loose.

Well FWIW I can tell you to be wary of the Hornady 4th Edition loads for the 155 gr bullet in the 10mm. They show a 13.9gr max with AA#7. I tried 13.0 gr and they ran 1400+ fps and bulged the case head over the feed ramp - Delta Elite with a Bar-sto barrel. Either they had a slow lot of powder, or I had a fast one, one of the two. 12 grains was fine, and so were Norma factory loads, so I don't think it was an over-ramped barrel.

The hottest load I have shot with a 45 is 16.5 gr AA#5 185 gr and the primer pocket gets loose. Clark; Here's your post on those loads over on TFL: 10mm Book load: 7.8gr "Hi-Skor" 800X, 200 gr1130fps 32500 psi
10mm Full load: 14.2 gr., 800X, 200 gr. .658", G20 Barsto barrel, small case bulge, must stop work up
If 7.8 grains was generating 32500 psi, just what do you think 14.2 grains was generating? QL doesn't list 800x as a powder choice. The .45ACP load QL estimates pressures around 70k PSI, and I'd be rather surprised if the 10mm overload with 800x wasn't comparable. Considering these were the other loads listed in that same post, I'd have to wonder how much you actually LIKE your hands and eyes... 40sw book load: 6.3 gr "Hi-Shor"800-X, Speer 200 gr. FMJ, 925 fps,
40sw FULL LOAD: 15.5 gr. 800X, 200 gr 1.171", G22 barrel with welded up feed ramp and re cut, no more powder will fit, even with double compression, horrific recoil
44 mag book load: 15.5 gr 800X 200 gr 1.610", 1600 fps, 39,800 cup

After having fired an old Colt Peacemaker in .38-40, I'd be very tempted by a Convertible Ruger BH in .38-40/10mm. E

E;
Ruger made a limited distributor (Buckeye) run of those about 20 years ago.
I think I know a shop that has one; I'll pass that info on if they still have it.

On the other hand i have that ruger buckeye shooter which i have shot in 10mm. Haven't in 38.40 yet due to the cost of ammo and not having bought the relative expensive brass for reloading. that 10mm round of 200 grains xtp flies out of the ruger at around 1300fps. the first peacemaker i fired at about six years old after bugging my dad. It was carried in territorial days here in arizona. One round, and i didn't tought it for years. I take certain humor that it is ballistically similar to the .40s&w today.

I see there is now a .38-40/.40 S&W convertible Vaquero available now, FWIW. I guess you could fix it with a few turns of a 10mm reamer The only revo I like better than a Bisley Blackhawk is a N frame Smith, and I found one of them. Decisions...Decisions...

Not a good idea for a putz, but I have been doing high pressure constantly for 10 years in dozens of cartridges.

E Hey E, You remember the "Freeway Killer" who took pot shots at motorists along highway 80 near Auburn in the '80's (killed 2 IIRC). When he was caught, that's what he was caught with. Psychotic idiot, but good taste un guns.

I could test a whole lot pf dumbphuckitude, 'til it caught up with me, and figure myself smarter than the average bear in the interim. You still didn't answer the pressure questions one the overload, however, and I'm curious as to how you actually test that pressure, too. BTW - the argy Mauser is a slick rig. THAT makes sense.

I have strain gauges and Quickload predictions and it is all abstract.
The effect on the brass is the reality.
Some people do not agree with me, which reminds me of a joke... er true story 30 years ago...
A New York cab had a flat tire. The passenger suggested that the cabbie put the spare tire on. The cabbie protested with a thick Pakistani accent, "I cannot. My training for this job was that I cannot drive anywhere without an inflated spare tire in the trunk. And if I change the tire I will not have an inflated spare in the trunk."

Clark;
What you do, with your own stuff, is your call. As I said, I like me more than that. If it's being a "putz" when I don't really want to set a grenade off in my hand, then so be it.
So, if you have the strain gauges and a QL version that lists 800x, what were the "abstract" numbers relating to the PSI levels of the 10mm and .40S&W loads?
