Trail Gun 10mm Magnum?

I know that the Trail Gun is available in 10mm and 40 S&W. Could the Trail Gun be chambered in 10mm Magnum?

From my 7.5" Single Seven, the cylinder measured 1.456" and the rim on .327 Federal Magnum is 0.055". This implies that a lower bound for the maximum OAL of a cartridge that may fit is 1.511". I took five-cartridge samples of three 10mm Magnum loads from Double Tap (the only factory loads that I am aware of), measured their OAL, and I got the following results:

. . . . . . . 230gr Hardcast
. . . Max: 1.5125"
. . . Min: 1.507"
. . . Avg: 1.5107"

. . . . . . . 200gr Hardcast
. . . Max: 1.4915"
. . . Min: 1.489"
. . . Avg: 1.4899"

. . . . . . . 135gr JHP "Controlled Expansion"
. . . Max: 1.5105"
. . . Min: 1.508"
. . . Avg: 1.5092"


It looks like the 200gr and 135gr would fit, and a few of the longest loaded 230gr may not. To be sure, the 230gr would certainly fit if: (1) the headspace allowed an amount of the cartridge equal to the thickness of the rim plus a couple thou (i.e., a fraction of the thickness of any moonclip) to hang out the backside of the cylinder; or (2) the cylinder were a couple thou longer and the barrel extension a couple thou shorter. Of course, since this is mostly a handload cartridge, proper bullet seating depth makes this academic.

Putting aside fitment, the more important question may be, what happens when you fire such a cartridge in one of these little guns? There are some factory 10mm Auto loads (e.g., Buffalo Bore Heavy Outdoorsman 220gr @ 703 ft-lb and Heavy 180gr @ 728 ft-lb) that come close to the bottom of these Doubletap 10mm Magnum loads (230gr @ 798 ft-lb) but the other 10mm Magnum loads are ~1000 ft-lb. My Single Seven weighs only 38.4 oz. I imagine recoil would be stout.

(1) Would this gun be able to handle 10mm Magnum?
(2) Would the average shooter be able to handle it?

now that you have gone to all that trouble it doesn't mean

diddly. A single action doesn't use moon clips plus we build our own longer 5 shot cylinders plus take a slight amount of metal out of the frame. So all those figures don't mean anything. Plus in a short barreled Trail gun you won't get any extra FPS or at least not enough extra to warrant going to the 10 magnum. You might gain 50 fps over the standard 10mm but that is all we have experienced.

our test gun was a 5 1/2" Redhawk.

While it’s possible it’s not as much fun.

Huey and I figured how to seat long and get full 10mm out of .40 S&W cases and 10mm Mag from standard 10mm auto cases. Great versatility. A “Trail Gun” on the single six chassis Is only 4 oz. or so lighter than a bigger chassis OM size chassis.

Keep it real.

I've seen a 41 Magnum built on an O.M. Single Six...

I thought a terrible idea. But, the guy shot it. Also, a six shot 357 Magnum on a New Model Single Six.

I'd considered these builds, but decided I'd be replicating my existing FA-97s.

The 10mm Magnum duplicates the 41 Magnum using the 40 Caliber bullets. JT first stated this in his 10mm Magnum Review.

I decided to go Double Action in my pursuit of the 10mm Magnum. With moon clips it'll shoot 10mm Auto and 40 S&W too.

To do another I'd go .38 Super, a GNR superb idea.

Or I'd twist his arm and get him to make me a .22 K-hornet chambered cylinder so I could go as long as the chassis would allow. Sort of a modernized .224 Harvey K-Chuk. I'd revisit that in a SA any day.

The .224-32 FA is great using .32 H&R brass and ignoring most of what Bob Baker preached. Not always a good idea...

My first Trail Gun was a 38 Super...

Later, I sent it back to a 9mm Cylinder.

I figured a 9 would set back easily

Don't EVER shoot aluminum case ammo in it! Since the 9 is tapered and made literally all over the entire earth I just figured it was a challenge.

But now you mention it...,

I do have a Blackhawk cylinder. Shoots like a dream. I forgot all about it.

our very first Trail Gun wasn't really a

Trail Gun. It was simply a Single Six chambered in 38 Super. We built it for a young lady in Alaska named Sarah.
