Keep in mind the 321 GNR (32/357 Magnum) is possible in the O.M. Single Six. With an 8" barrel this would be manageable and a screamer. Isn't the 321GNR a 32/357 MAX not magnum case necked down? |

Nope, its the 357 Magnum necked down to 32 caliber.

If it's a matter of case thickness as opposed to cylinder OAL and you use Dick's version of the 30 carbine/ .32-20 cases, are you gaining anything if you load the Sledgehammer in those reformed cases?

It might well be the ultimate small bore in a Single Six size sixgun although the available nose to crimp might require a design specific bullet mold. So if the S7 can do nearly 1500 fps with the 115 the 321 GNR might do 1600 with a 125-130 grain bullet. |

Perhaps Dick might set his Huckleberry shake down long enough to make up a dummy and let us know! |

I am glad I don't have a set of 30x221 dies or I would be messing with some max brass. That's pretty sad as I just moved over 90 sets of dies around, and for sure none in the mix.
I am trying to wrap my head around the 41 as to what it would look like. I don,t think a 30 BR or Herrett will neck 41 mag down much if any.
I am thinking here.................

What we might really need here, is for our very own bullet designer man to come up with a purpose specific bullet. I have sent him a PM.... I answered it BEFORE I read this thread. What I need to know is max bullet diameter you want on the driving bands as cast and the typical cylinder throat diameters you've measured along with land and groove diameters in the barrel near the throat. Give the end of case to end of cylinder dimension along with a range of bullet weights wanted. You guys know of course that Paco Kelley has written the Lyman 311440 up in the Ruger 30 Carbine extensively..................... |

I've got an OM .30 Carbine and shoot the Accurate Molds 31-120S...can't remember the charge of H-110 but the bullet is running 1480 fps. It is sized to .309 I believe.
Using the same bullet sized to .313 in the 6.5" Freedom Arms 97 6.5" they are running 1400 with AA-7.
Have not pushed them harder but zero leading so far and it is not a gas check bullet...

What is the key in getting a bottle necked case to work in wheel guns? Looks like shoulder angle and neck length?
Seems like Reeder has this figured out?
I fooled with a Bain and Davis years back, TC platform though.

I fooled with a Bain and Davis years back, TC platform though. Jeff This article covers the intricacies of getting bottlenecks to work in revolvers: www.singleactions.com/327MartinMeteor.htmlOn the subject of heavy 32's, Todd Corder once sent me some 135 grain bullets. I just had to trim the necks back ~0.060". They approached 2,000 fps in the Meteor. 85 gr XTPs can hit 2,250 fps. It's hard to squeeze much more speed from a 32 wheelgun. But I do have another hot 32 drawn up that may prove that point. .327 Martin Meteor, 85 gr XTP:  -Lee www.singleactions.com"Chasing perfection five shots at a time" |

That's like putting a cold beer, big steak, and a crisp salad just out of my reach.....
It might be nice of you to enlighten the unwashed....

Bobby Tyler, of Tyler Gunworks, who evidently can color caseharden anything to include stainless steel and my newest business associate is sending my a 30 Carbine cylinder. As soon as I have it in hand and am able to see where on Earth the throats are I will have a better idea of what limitations my design envelope will have...

It's based on our .375 Atomic, with the brass cut to 1.50". Or call it a .375 SuperMag trimmed 0.100". Necked to 32, sidewalls fire-formed for no taper, and a 40 degree shoulder. The 1.50" length will be used for 85 and 100 gr XTPs. Longer bullets will require necks to be shortened 0.050" - 0.070". -Lee www.singleactions.com"Chasing perfection five shots at a time" |

I am surprised that the 135 hp won't fit the .30 carbine cylinder. I've never run it in a .30, having sold my 30 carbine off before I acquired the Miha sledgehammer mold, but I would have assumed that the oal of all the Blackhawk cylinders would be the same. Interesting bit of info. May have to see if I can scrounge up a .30 carbine Blackhawk....... 8- Dad burn old age, just saw while cruising some older notes we've cover the cylinder length question before and it is shorter...  | It might just be Dick's lot of brass. I have a report from Bill Fowler, who is shooting 30 Carbine in a USFA that the Sledgehammer sized 311" does indeed fit. I need more 30 Carbine owners to size down the current Miha 314-640 designs to fit the 30 calibers and see if they will fit, see if they will shoot, and check them at longer ranges for accuracy... |
