Taurus 40 S&W revolver?
« on: September 24, 2013, 04:01:55 AM »
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.

Some guys get great guns.  Others get lemons.  I personally plan on taking the chance someday.  I will probably ream the cylinder to 10mm length too, since I own a reamer.

You think a gun designed for only .40 S&W can handle the extra pressure of a 10mm?

Some people think I'm paranoid because I have so many guns. With all my guns, what do I have to be paranoid about?

The 10mm is only 2500 psi higher MAP than 40 S&W (37,500 vs 35,000).

The 10mm obtains it's higher velocity due to a longer cartridge and therefore a larger initial volume of gas at that pressure.  The result is a flatter pressure curve/slower pressure drop as the bullet moves down the barrel.

My EDC is a 40 S&W gun converted to 10mm by reaming the chamber.  I have thrown very heavy loads at it and it runs them just fine.

A more correctly phrased question might be "Do you think a gun designed to handle a recoil impulse of .88 lbs/sec will stand up long term to a recoil impulse of 1.20 lbs/sec?"

The answer is again yes, since the base gun is actually a 357 magnum, and the 357 magnum recoil profile matches 10mm very closely.

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.

Yes, that is a Ruger GP100 the was converted by Reeder Custom to 10mm Magnum.

Here is a thread about it right here on our forum:  http://10mm-firearms.com/10mm-revolvers/10mm-magnum/15/

So, you can't generically say that since he didn't think a Herters Powermag (JP Sauer and Son mfg) 357 would stand up, that no 357 would stand up.

That said, I would not expect a Taurus 405 to be in great shape after 2000 full bore 10mm rounds either.  I interpret Gandog's question to be around safety, not long term durability.  I really don't think a taurus 405 would be in great shape after 2000 rounds of full bore 40 S&W, or that a 605 would be in great shape after 2000 rounds of heavy 357 magnum.

They are meant to be shot a little, carried a lot.  And I do think a 10mm Taurus 405 would be just fine on a diet of 50 rounds a year of full power 10mm and another 200 - 300 or 'practice' level 10mm.

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

Actually, a bit of both, but safety is ALWAYS first!

sqbullet did you ever get the 405 and ream the cylinder for 10mm?  I have the same revolver and was thinking of the same.
Thanks

I haven't.  House project interfered.  Still on the bucket list.

I just sort of wish S&W would come back with the 610 at least.  Ruger, maybe through Talo or whoever could also do a 40S&W/10mm convertible in a SA revolver.
