Mission accomplished! I now possess the world's first Col New Service in 40S&W! And can she shoot. Pix available but I need to upload them.

Hi:
I have been looking high and low for a mission statement of some sort regarding this website.  I must be looking in the wrong places.  The reason: from reading the different posts here, I'm lead to believe that the site involves just the 10mm Auto cartridge.  I thought 10mm/40 caliber type ammunition would be featured here (38-40, 40 S&W, 401 Powermag, 400 Corbon, 10mm Magnum, and the like) was the purpose of the site but maybe I'm mistaken.  Can anyone comment? Thanks. BH38WCF.

Got in contact with one 'smith who tentatively agreed to boring out my New Service cylinder. I have to supply him with the reamer before he can do the work. Stay tuned. BH38WCF.

Has anyone shot this revolver using full power 40 S&W loads? What is the recoil like? Thanks. BH38WCF.

I beg to differ. Apparently,  you haven't carefully read my description of the gun.  I'm sure I can do way below the costs you think it would cost me.  You said it yourself: you are no gunsmith. Watch me. Besides, I never said anything about modifying the 357 cylinder to 10mm. Sincerely, BH38WCF.

Hi DM1906, you have the first portion of the message correct. But you also mentioned that "Given that the bids 38-40 New Service or M1917 seem to be around $600-$800 and that Bowen charges $750 for this type of conversion to your gun, I think you would be better served to sell your New Service and start shopping for a $1000-$1200 610."  Uh, no.  First off, try more like $1500 for a 610 just for starts. 2nd, the title of the post was a "junk 38-40." Due to the previous work done on this revolver I previously stated, the estimated collector value stated here doesn't apply.  This is approximately a $150-250 dollar gun (in fact, I think I bought it midrange of this pricing), especially with the 7.5" stainless .401" barrel installed. Not only that, the 38-40 cylinder is well worn.  The rest of the New Service appears tight and the barrel seems to be good and nearly new.  Besides, a typical rechambering of a cylinder can run around $200-300 depending on the 'smith doing the work. Even if the work totaled $700 everything included, it would be worth it for obvious reasons. In fact, I'm working on a variation of the theme. Stay tuned. BH38WCF. 

Be careful! I emailed Gary Reeder on the possibility of rechambering a 357 Magnum cylinder to 10mm auto for a 401 Powermag revolver.  He doesn't recommend it he claims it will shake the gun apart.  Now this is on a revolver that has near Ruger Blackhawk type qualities (the Herter's 401 Powermag).  I don't think the Taurus 40 Smith has that type of construction. FWIW. CJ. BH38WCF.

After reading the various threads regarding the different 10mm type revolvers, I had an inspiration.  I commented about the Chiappa 40 being used and someone remarked how thin the walls of the cylinder would be on that revolver.  But they do make it in 40 S&W so the thin-ness of the cylinder wasn't an issue. However, what surprised me was that Chiappa used a form of high tensile strength aluminum as a basis for the frame of that revolver.  This could withstand the pressures of the 40 S&W cartridge, which operates nominally around 33-35 KPsi. I also thought "didn't the New Service have models made or converted to 357 Magnum, which is basically the same pressure as the 40?"  Conversely, Chiappa also makes their revolver in 357 Magnum.  In the past, M1917 revolvers were remade into 357 Magnum revolvers using a Numrich Arms conversion kit.  May of these converts still are safely used today. Well, if this type of conversion is fine for the M1917, why not a conventional 38-40 New Service? After all, the ordnance steel used in that era seems to be tough enough to safely shoot a 357 ctg.  I do have a spare 357 Magnum cylinder for a New Service that I can have rechambered to 40 S&W.  And, the 38-40 N.S. I have has a stainless steel heavy barrel on it (don't ask why. I bought it that way).  But the cylinder is loose and likely needs replacing.  So there is no collector value on the New Service.  Well, as I am apprehensive about this type of conversions, putting this information together theoretically makes sense.  With the Chiappa in the 1000 range and the 610s subject to bidding wars and out of my price range, a conversion of this revolver to 40 Smith might be a solution. What do you think? BH38WCF.

One more thing: I forgot about this little jewel. It can be had in different barrel lengths to include 6".  I may have to save up for this one since the 610s seem to be near unobtanium: http://www.outdoorlife.com/blogs/gun-shots/2012/01/chiappa-firearms-offers-rhino-revolver-40-smith-and-wesson

Anyone have one of these? If so, how do you like it? Personally, I'm not a fan of short barreled "belly guns." However, with the apparent shortfall of Smith and Wesson 610's, that (and the competing Charter Arms Bulldog using the same ctg) are the only alternatives. Personally, I wish either would produce a wheelgun with a longer barrel, target grips and target sights to at least temporarily staunch my lust for a 610. BH38WCF.

You forgot at least one more "production gun" the Herters 401 Powermag.  This is a true 10mm revolver in a rimmed magnum package. BH38WCf.

I can imagine the nightmare of trying to find brass for that to reload..........

As DM1906 sez, making the brass from these cartridges is not too bad of an answer.  Also, one can get loaded and empty cartridges from an outfit called Gads Cartridges (search it out). Finally, if one gets spare 401 or 357 mag cylinders for the Herters, it would be a simple matter for a custom gunsmith to rechamber these to 40 S&W, 10mm Auto, or 38 WCF (38-40) for the ultimate 10mm revolver.  At least one of these rechamberings would solve your cartridge quandary (especially the 40 S&W selection). Oh yeah, I believe 41 Long Colt can be included here.  There are technical issues regarding this cartridge (as it was originally sized at around 0.390" diameter) but later iterations included expandable base lead bullets (think Minie ball bullets) that would take up the extra slack.  Imagine: one gun, multiple calibers: 401 PM, 40 S&W, 10mm Auto, 38 WCF, and 41 LC.

Hi:
I'm CJ and I happened across this site while looking for info on the 10mm Auto.   I'm from Tampa, Florida and currently, I do not have any 10mm type firearms.  However, I am in the process of building one up. I recently purchased a like new Colt Delta Elite Slide.  My plan is to buy a Caspian Arms Recon Race stainless frame and mate the two to become a "Colt-spian" Delta Elite.  I do have new barrel for it from Dan Wesson chambered in 40 S&W but also plan on getting a barrel for 10mm.  Aside from that, I am into anything related to 10mm cartridges, to include the 38 WCF (a.k.a, the 38-40 Winchester), hence my handle, the 40 S&W, 400 Corbon, 10mm auto, of course, and Herters 401 Powermag. In fact, I have about three of these revolvers chambered for this round and I will be getting spare cylinders to have them rechambered for 38-40 and 40 S&W (401 Powermag is a hard round to find). I do have an OM Blackhawk being built up in 38-40 but plan on building it for an additional 40 S&W cylinder.  I am also a fan of the 41 Magnum and have several guns in this caliber, the Dan Wesson 741 being my favorite.  Best regards, CJ, bh38wcf.
