Ruger SRH 10mm?

It's a lot of gun for the cartridge and I suspect will have limited appeal. Maybe for those who want a proper hunting platform chambered in their favorite autojammer cartridge. Maybe for those averse to 44mag, 454 and 480 recoil.
We bought a SRH in 10mm. I did somewhat know what to expect as we have a 10mm/38-40 Blackhawk and it is a keeper. The SRH 10mm is fast becoming my favorite but that could be in part because it is the latest revolver. Pleasant to shoot, hits more than hard enough for any hunting application in our area, and VERY accurate. I missed getting a 610 Smith when they were dropped from the lineup and now the prices on them are nuts. IMHO the SRH is at least as strong as the 610 and it feels solid when you shoot it. Very happy with the revolver.
While the 4" may be fine, I personally have no interest in short barreled revolvers but some folks really like them. The 10mm does head space on the case mouth. You can shoot rounds without the moon clip but you then have to take the cases out individually as the ejector will not remove them.

You could ream it for 10mm magnum and shoot all three in it. That'd give it a good boost in performance and allow the use of better powders.

I am really impressed with the way it performs now and reaming the cylinder would provide no advantage for what I use it for; target and maybe some hunting. I would be concerned it may hurt the accuracy, 10mm magnum is a more difficult to find cartridge, and it may even hurt the value of the revolver. I just have no interest in a 10mm mag.
I bought a 610 back in the early 1990's. Great gun. In fact I am planning on taking it to my monthly ICORE Match this morning.
I do agree with reaming a Super RedHawk to 10mm Magnum for hunting. The 10mm case is a little lacking in space for magnum pistol powders. I just loaded 100 rounds of 10mm Bear Medicine for a buddy using 200 grain XTP's. I had not loaded any Full House 10mm in several years. My first Book Load that looked promising AA#9, ended up being a compressed load. I ended up going back to Blue Dot. More case space would have made AA#9, and probably H110 a lot better choice pushing a heavy 10mm bullet.
No problem getting 10mm Magnum Brass, Starline should have plenty.
One thing that I am sure of. I would rather shoot the Thermo Nuclear 10mm loads that are being put together for hunting through a Super RedHawk than a 1911 based semi auto, or a Glock.

Do you have a 10mm semi and does it jam? I own a Para LS Hunter and have put over a thousand rounds through it with no jams?!?! What gun do you own?
Yes, and no function issues. Javelina and a Sig P220
How would Heavy 10mm Magnum loads going to keep the bullets from creeping out of the case?
I have had some 44mag and 45Colt Blackhawks that required a very heavy crimp to hold the bullets.
This would make using a moon clip mandatory, and would affect standard 10mm accuracy.
Are there any 10mm bullets with a crimping cannelure?

If you did the rechamber, you'd obviously be one that didn't really care about any slight degradation of accuracy with standard 10mm. You may even gain accuracy with the magnum because you're using more of the cylinder length.
We're talking about an existing semi auto round but if you did have problems with the bullets creeping out, you could always roll crimp and use moon clips. Which is probably what you'd want to do anyway. Any 38-40 bullets will have a crimp groove but a cannelure can easily be added to jacketed bullets. Beartooth has a really nice 200 grain wide flat nose. Just saying, it's an option.

Years ago in guns like the Automag 3 and LAR Grizzly. Maybe the Wildey too but I don't remember for sure.
If Ruger had done a GP100 in 10MM, I'd definitely buy one.
The issue becomes cylinder size. If you make it a 5-shot, no problem. The cylinder walls become thin at 6-shot. Clements does 6-shot GP100 conversions to 10mm but states, "This is a medium frame gun and should be treated as such. Ammo which is loaded to maximum pressure levels should be used sparingly." I don't see Ruger doing it for liability reasons if nothing else.
Looks like another short run Ruger firearm to me.
Why not a 3" 9mm, 40 or 10mm GP100?
I saw the Super Redhawk in my last American Rifleman.
Seems pointless to me.
You must be referring to the 10mm wheelie already discussed & debated extensively here:
https://thefiringline.com/forums/showthread.php?t=590967
As far as Ruger chambering the 10mm AUTO in/on a particular a frame-size, ... yeah, they could've done it easily on the standard RedHawk, just like they did with the .41Magnum RedHawk, and there wouldn't have been any issues. And yes, the GP-100 frame was do-able too. In its maximum loadings, the 10mm just begins to tread into the fps/fpe specs of low-end .41 Mag loads.
That said, the 10mm SRH - for those that get one - will most likely serve as the base- or doner-gun for "conversion" to 10mm Magnum by having the cylinder chambers reamed out to Magnum specs, a not uncommon practice among S&W 610 owners, especially those with the 6.5" model. It's a job most competent revolver-smiths can do in their sleep (Hamilton Bowen being one name associated with this conversion).
One immediate utility of the conversion is the ability to use the same moon clips to load and shoot .40S&W, 10mm AUTO, and 10mm Mag cartridges all from the same gun - 3-in-1 fun.

Same as with any other cartridge - crimp. See Taffin's report below. No report of bullet creep.

Yes on the moon clips.
No effect on "standard 10mm accuracy" reported from owners of converted 610s; however, some did comment on seeing a degradation in accuracy when shooting 40S&W ammo post-conversion, due to the longer bullet "jump."
Remember, on the 10mm Mag conversion, we already have a base of user experiences from the Smith 610s that were converted long ago, so you might want to Google for that and do the research before you decide one way or the other ...
Rafsob: I must admit I have the 10mm in my Para LS Hunter,but didn't know about the 10mm mag. When did they come out with that?
John Taffin's 10mm Magnum article and load tests here:
http://www.sixguns.com/tests/tt10mag.htm
Additional 10mm Mag info and load data:

Note there are some references comparing max levels of the 10mm Mag to the .44 Mag, not the .41 Mag.
For what it's worth, here's Taffin's concluding take-away:
The 10mm Magnum has definite applications as a hunting pistol and a long range silhouette pistol. Shooting informally at long ranges of 100 to 200 meters and using rocks as targets convinced me of this. Anything the .41 Magnum can do, the 10mm Magnum can also do and perhaps do it even a little faster and a little better. That is a tough confession for an old sixgun man to make.
