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 Makes sense...everything that holds that cylinder in place takes a beating. Both the S&W 69 and FA83 (available) are 44 Magnums. But, surely one will hold up to heavy loads longer. |

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. That makes sense. Thanks for explaining 🙏 |

Might I offer one more idea to the mix. Try some slower burning powders. With the longer barrel, you could most likely benefit from a slower rate of the gas reaching the maximum peak. I used 680 which I believe is sold today as 1680. Or, you could check the burn rate chart and find others that would fill the bill. I only had a six inch barrel on my custom Bowen Redhawk 44 magnum, but it was comfortable to shoot with as much 680 that would fit under the bullet I used in that weight range. The heavy bullets from that cartridge would penetrate any longhorn ever born.

I don’t have wuickload. lar4570 would you be willing to run this new powder through your program to get me a safe starting load? 🙏 |

The rest gets Remoil. |

5 shot over the chrono gave me an average 805fps.

Way slower than expected but very consistent. Very interested to see how penetration on water jugs goes.
