thinking my next project needs to be a 375 revolver that uses 30-30 cases as the base case... any of you guys played with anything similar???

Have a 375 GNR. Basically a 445 Super Mag case necked down to 375 caliber.

I'm thinking a straightish case, no bottleneck... similar to a 357 magnum, just 375...

375 Super Mag been around for years. Still see Dan Wesson revolvers for sale in that clambering.

that's about the only "semi mainsteam" revolver cartridge I can think of in 375... I have a couple Dan Wessons... wouldn't mind adding one in 375 Supermag... but honestly, since my buddy likes working on single actions... I've been leaning on doing something in 375 in a single action Ruger  |

seems we have someone right here that has thought this out, long before I did... www.singleactions.com/375Atomic.pdfI'm still reading, but what I've digested so far, this is very similar to what I'm looking for... Thanks LEE |

I'm pretty sure BFR makes a 375 Winchester. It's not my cup of tea but it's a 375 bore on a 30WCF case like you requested.

thanks... I have a couple "long cylinder guns" & while there is the smile they put on your face, I just don't like the balance & looks of the super long cylinders ( was looking at buying a S&W 500 X Frame, but a Ruger 480 is going to replace those desires ) I do have a 375 Winchester 14" Contender barrel, & the "blast" is even more than my 35 Remington or 45-70 hunter barrels, so I'm quite sure a revolver in 375 Winchester would put a smile on my face that said, I think I'd rather do a special or regular magnum length cylinder gun... LEE's story is right up my alley... hope there aren't any patent rights that would keep me from building one on a Super Blackhawk hunter or ? |

I’ve done a lot more with the Atomic since penning that article in ‘04. Give me a ring if you’re serious about building one. I’ll fill you in on some other bullets I’ve tried plus an LFN I have in the works. .375 Atomic – second from the left  And our third Atomic conversion:  -Lee www.singleactions.com"Chasing perfection five shots at a time" |

I thought of doing a 375 Special or magnum length case, 1.285" or so, just to get around some gun laws in south America.

thinking my next project needs to be a 375 revolver that uses 30-30 cases as the base case... any of you guys played with anything similar??? Magnumwheelman.... Lee has worked extensively with the .375 bore in various cases. My shooting is limited to the .375 Super Mag in Sig Himmelmann's Seville 10-1/2" and the Dan Wesson 8" revolvers. Due to the relatively high ballistic coefficient of .375 bullets, groove diameter must be snug. The parent .375 Winchester works a tapered chamber, which tends to highlight brass formed from the softer .30-30 case. A single action may be set up with a cylinder gap of .001-to-.003" without bind, unlikely with a swing-out cylinder, although entirely possible on a Super Redhawk. Don't remember whether .375 Win brass wears a thicker web than .30-30; for sure I experienced easier extraction and longer loading life from Winchester .375 brass. IHMSA All-American and International Champion Eric King threw down with his Seville .375 Super Mag in the 500 meter game until his revolver broke. If it is true Magnum Research so chambers their BFR, then this revolver I would seek against those reach-out rams. Especially pick Lee's brain on a straight wall bottle-neck. To neck a .454 Casull to .375 might be an option. I'd want it a 5-shot. David Bradshaw |

While a digression, or hijack, another option might be a .357 Herrett in the long frame BFR----a specialty revolver to reach out yonder----might hurl down-range punch for a bit less loot. The BFR .30-30 was my first suggestion to Eric King after his Seville .375 Super Mag let go. (Lee and I discussed the blow-up and it is Lee's take that the Seville in question may be among some frames which were not up to snuff.)
Jeff (aka "jhs") whom I don't believe I've met but who obviously knows his way around Silhouette, is hard into the cast bullets and may have his own ideas here. Certainly, cast heavies reach full steam on a softer pressure profile than jacketed in magnum class cases. Eric King cut 7 grains off the nose of Nosler .375's for excellent worked up accuracy @ 500 meters and electrifying punch on the 55 pound T1 steel ram.
Why do we assign outlandish chores to the lowly revolver? Answer: makes us feel good, complete for a moment. Actually surprises and gladd6ens me that a contemporary such as Eric King dares paint iron sights on the 12-inch torso of a ram 5-1/2 football fields away----with a REVOLVER!

See, now that's what I'm talking about. Not a max frame, just a Ruger large frame revolver with a 375 bore cartridge.
The police say in Ecuador you can't have a revolver "bigger" than 38 Special. So I asked, if I had a 375 Special/Magnum would that be ok? Even when I told him the 38 Sp was the same diameter of the .357 magnum he said "sure, that works."

Magnumwheelman.... yes, talk to Lee. My feeling for a 5-shot cylinder once you go above the .357 Maximum chamber is informed by the incredible toughness of the Ruger Blackhawk with its fine metallurgy and the shameless torture we put those guns through. All of which substantiated my belief in wrapping meat around the chamber. Thus, my 5-shot recommendation for a Super Blackhawk .375. While a bottleneck provides more boiler room, it exposes the skirt of a heavy bullet to combustion theatrics, not to mention weaker grip at the moment of ignition.
Consider in designing this build the selection of case + bullet together, so that the revolver is built around the load.
