That looks like a very interesting bullet. A plain base lubed bullet should be fine at 1000fps. If they are already lubed and you try to powder coat them, I think it will just cause a big mess. I would imagine that the lube will melt out of the lube grooves and run down the sides of the bullet where it will mix with the powder coating powder. I think it will end up with a blob of powder coat paint mixed with lube at the base of the bullets. Do you have the bullets in hand yet? What is the length of the bullet? I looked at MBW website and it showed the nose to crimp length was .380" They arrive on Monday. I’ll post measurements when they arrive. Copy on powdercoating 👌 Fiddling around with powder charge is going to be interesting. MBW said I could actually crimp ahead of their crimp grooove if required due to the short cylinder. I eventually want to start casting my own stuff, but for now these should be a slick load to bring along to AK and sit the berry fields for this bear season. |

I'm a huge proponent of the Bad Boy and Callahan. But, won't shoot anything heavier than a 240/250 grn in mine.
I suspect those heavies will shake these guns loose at an early age.
Good luck...

I might have to experiment with the Cimarron warranty then 😬 It definitely won’t be a steady diet and I realistically plan to mostly shoot/hunt with a powdercoated soft-medium cast 190gr SWC HP in this gun. |

I looked at MBW website and it showed the nose to crimp length was .380" Bullet length is exactly 1.00” This 370gr feels ultra heavy! They look really good. I can’t pickup my revolver until Friday, so I’ll have to swing by the gun shop to see how my dummy round actually fits.   |

Okay, from Quickload. 44mag, 6" barrel, modeled at 7.5" 370gn cast 1.00", COAL 1.633"
H110, 15gn - 990fps @ 26kpsi 94.7% load density
H110, 16gn - 1067fps @ 32kpsi 101% load density
This is just a Quickload guestimate, not actual load data.
I would not go any lower than 15gn H110. H110 isn't too happy when loaded lighter than 95% load density.
Glenn.

Man, that 370 grain bullet is impressive looking! I might have to try some of them out just for my personal amusement. I sure don't need anything that large here in TX! Well, maybe if I start hunting longhorns...

Way back when... sometime in the 90's... A friend had just received a Linebaugh built 475. We had been anxiously awaiting it's arrival and already had cut down some win 45-70 cases, ordered .476" cast bullets and had several pounds of 296 standing by. Shooting it was an absolute eye opener and left me with a severe case of .475 envy. I had a 4 5/8" Stainless Ruger Blackhawk in 45 Colt and wanted to see just how close I could get to the 475. I called my favorite cast bullet house and asked if they could size some of their 405gn 45-70 bullets down to .452". They said yes, I ordered a few boxes... This was pre Quickload days, so I just sort of swaged it. I'm glad Ruger builds these things strong. I got to around 1200fps before I stuck a case in the cylinder. Who knows what the pressure was, but I'm sure it was way too much. My friends Bisley that he sent to John was a 45Colt, so I bought his returned cylinder and fit it to my Blackhawk.  |

Thanks for sharing that information 🙏 That gives me a great starting point. 990fps seems like it’d be more than plenty for such a heavy beast. If it’s not too punishing, I’ll work up to that top end load just for giggles and see how I feel. |

Well, maybe if I start hunting longhorns... I’d love to hear about that hunt! I’ve heard stories from several old timers down in Texas about how tough those old bulls are and that they’re pretty hard to kill. |

Not to be argumentative at all, just always trying to learn… If the Cimarron is billed as a 44 Magnum revolver and SAAMI rates the cartridge at 36kpsi, wouldn’t it be reasonable to expect the revolver to handle loads up to 32kpsi without the gun coming apart? I have zero intention of beating myself or the gun up just to prove a point, but it would seem foolhardy for a well-respected company like Uberti to put their name on something that wouldn’t stand up to the task they gave it. |

Well, I'm not sure how heavy bullets and guns shooting loose translated into pressure and guns coming apart... But, heavy bullets (more mass) requires more to get started moving. This translates into more push back on the cylinder and what holds the cylinder in place. Simple physics and takes its toll. Put a Volkswagen and an F250 in neutral and see which one takes more "push" to get moving. Mass is mass regardless of application. The human will get tired pushing more mass quicker than the same human pushing less mass. Any revolver can be shot loose. Some habits can extend the life, some habits can shorten the life. |

One of the important things John told me about maintaining my 500 was to make sure to keep oil on the base pin and a dab of oil on the ratchet and nose ends of the cylinder. He said the oil would dampen the impact of the cylinder coming back so it wouldn't batter itself on the frame and deform the ratchet end.
He said that he had received guns back from guys who constantly shot them dry and they had developed end shake.
FWIW
