1200fps out of a six shot Blackhawk, looks real close to stock so I'll save the pictures, not that I even own a camera, but what I am now calling the 480 Barnes (due to worries about copyright infringement calling it a 480 Achilles Long) is done for the moment. Heeled bullet gave groups averaging 3.5" at 25 yards to boot, just that they're about a foot low because mt rear sight doesn't go down far enough and I need a taller front. Does anyone know where I can get a pressure barrel made. This equates to a healthy amount of muzzle energy (480 Ruger ish if I'm not mistaken) and I'd like to get some numbers off this one.

If it's shooting low, don't you want to bring the rear sight UP?

Come on, you really expect us to believe that??? A 480 grain bullet at 1,200 fps out of a 6-shot Ruger is a hand grenade. Want to share the load with us? -Lee www.singleactions.com |

Lee, I think he is talking a .476 bullet in the 45 colt case. I may be reading it wrong though......As far as the sighting, I think you have it backwards sir, best I can remember, you want to move the rear sight in the direction you want to move the bullet impact. The front is reversed, shooting high, get a taller front sight. If you are low, seems that you can set the rear sight in the middle and then adjust on the front sight if needed. But, the actual achilles round by the way if my memory is decent today was about a 300 grain bullet at about 800 fps out of a 7.5" barrel. 1200 seems a bit steep to me......

Zeus, it isn't the original Achilles, I lengthened the case enough bring it back up to the full length of the 45 Colt so it will feed through the levergun, the Achilles was too short and got stuck in the carrier by way of consistent double feeds, and the bullets I loaded, which were cast by a member of the levergun forum, weighed in at 350grns. +- a couple grns. in my mind making them a niminally 350grn bullet
PS, I'll post the load data when I can check the pressures, the cases were a little sticky but there's tool marks in the chambers from where I reamed them out by hand (don't have mill and couldn't find a local smith willing to tackle the project for me, so...) and I want to make sure I'm posting safe dope before I tell the world the specifics, and my backsight is as high as it will go so I figure I need a taller front to bring it back down to the middle of the sight's travel, and you're right about the 476 diameter, it went through a 475 bore Pac-Nor, but aren't all of the 480s actually 475 diameter?

Ya, he's talking about a heeled 0.476 bullet in 45 Colt brass. A 480 grain slug @ 1,200 fps out of a 6-shot cylinder is totally unsafe. I'm not sure you could get enough H110 in there to even do it using a standard length cylinder. Again, this is one of those post where no details are given, no load data is provided, no pictures are posted.....makes the whole thing hard to believe. Basically, he's claiming 5-shot 475 Linebaugh performance out of a 6-shot 45 Colt cylinder. -Lee www.singleactions.com |

That's exactly what I was going for, the data I used was to make 350grn. 45 Colt bullet go 1200 fps

In your first post you said you were shooting 480 grain bullets at 1,200. Now you've changed it to 350's at 1,200?  And you wonder why folks hammer you on this forum. -Lee www.singleactions.com |

My apologies Lee, meant 480 diameter, not weight, they weigh around 350, sorry for any confusion this may have caused

OK, that makes a lot more sense. I just didn't want anyone to think you could safely launch a 480 grain bullet from a 6-shot 45 Colt. -Lee www.singleactions.com |

There's no wa yin hell you could launch a 480 grain bullet from a Ruger 6 shot anything, but the project is doing exactly what I wanted it too, getting basically 480 Ruger performance from a six shot Blackhawk with no ill effects, I just wish I could check the pressures somehow, I'd like to post the data, if you PM me, and this only applies to LEE, and maybe AXEHANDLE and Aggie if they ask real nice I'll tell you how much powder I used, and there was tuft of space filler in there too.

Why would you use H110 and filler? If you aren't going to have 100% loading density H110 isn't a great choice. Adding filler doesn't equal 100% loading density. I would go with 2400. 350 grns at 1200 seems really high even considering that a .476 grain bullet has more surface area to work on.

Ha! You're not sending that data to my house! In fact I am looking at flight paths of all major airlines and making sure that they aren't passing over your house...  ;D ;D ;D |

"That's exactly what I was going for, the data I used was to make 350grn. 45 Colt bullet go 1200 fps"
This is a very confusing thread.... are we shooting "45 Colt bullets" or .476 bullets.
