Just wondering if anyone has reamed or honed the throats on their 480 Bisleys to even them up. With the Carpenter steel being harder (my understanding)can it be done by conventional reamers or does one need carbide or any other type reamers? Mine has three throats that are a snug .478 and too that will allow a .478 pin gauge to start but not fit all the way through Two of the three that does fit have just the slightest lip on the throat exit. A little wiggle will allow the pin gauge to go through.I've tried shooting as is with 4 different bullets (cast) plain base and gas checked. Different alloy hardness, heat treated and air cooled. I've also tried sizing from .476 to .477. I have some ready to load that has gone through a .478 sizer but will have to try when I return from work next week. I have also tried powder coating and traditional lube. The last session was with bullets from the Accurate 48-395 mold cast from an alloy that obtained 14 bhn air cooled. This gun wants to shoot as proved by my last session but I still had some light leading in the barrel. Does not have thread choke as I have checked. I get a little leading only in certain spots the full length of the barrel. This past session was not too bad. I think more than anything those uneven throats are what's the problem. It's not easy finding a reamer in .478. I guess I would have to get one made. Thanks!

My understanding is that the Carpenter 465 used for the 480 and 454 cylinders is not so much harder than the stainless, it is just stronger.
I would suspect that any reamer capable of dealing with a standard stainless cylinder would work fine for the Carpenter cylinders.

Stronger does not necessarily mean harder and in fact can sometimes even be a little more workable but handles pressure better due to being less brittle and better memory. |

Member DougGuy at the Ruger Forum or Cast Boolits can hook you up. He does excellent quality work, with a fast turnaround. Fermin/2 Dogs may also be able to help you out, though I'm not certain if he's set up to do the .480.

Thanks for the replies. It wouldn't take much. Probably some polishing would do it.

I’ve got the large set of pin gauges needed to measure these throats correctly. I just finished correcting a Ruger .454 Redhawk that was “sticking” cases on extraction. Carpenter steel can be worked with and I would be happy to take a look at it for you.
What you want is all your throats to be the same size. You then need a cast bullet correctly sized for those throats. I don’t charge to measure your throats save return postage. I can also measure and check the hardness of your cast bullets for you. I will PM you my contact information.
Remember I will help you with your leading issues even if you don’t hire me to do any work.

Appreciate that 2 dogs! I have pin gauges and hardness testers. The problem is the uneven throats. I always size to fit the throats but that's hard to do when they are different sizes. This gun wants to shoot and I believe it will be very accurate once everything is good to go. Contacted DougGuy and we talked about the throats. If that doesn't materialize I will surely contact you 2 Dogs. Thank you again for the offer.

I just got one of the short 480 Bisleys, throats feel consistent at a hair over .477" using guage pins. I'm concerned about the barrel forcing cone, looks way big. Winter is still here, so it may shoot ok as is, if I find some .477" diameter bullets.

I'm getting what is good for me, shooting from my 480 BSBH 4 5/8". But it is leading badly. This with the big HP bullet, PC'd. Jacketed stuff drop right thru the chambers. The PC'd hP's require a gentle push. The Lee 400gr FN a bit more of a push. Maybe the HP's could benefit from a 2nd coat of PC ? The LeHighs have shown up, so will be distracted by them for awhile.

Well, if you would like, PM your contact information. We could at least bat this around some. Be even better to have your cylinder and some of the bullets you are shooting. I’ve cured quite a few sixgunners ailments... |

As a follow-up, DougGuy has developed a method to ease the transition from chamber to throat in the .480 Rugers that shave rings of lead from cast bullets. At least some cylinders have very sharp edges at that point. He details the procedure here: www.rugerforum.com/phpBB3/viewtopic.php?f=41&t=265375It certainly looks worthwhile to me. |

Thank You 2Dogs. This is the BSBH with the hitch in the gitty-up. Has some other issues too. So have been holding off until I decide wether to mail to Ruger or not. I do not know why I'm hesitant, but with whats involved would likely get a whole different gun. The hitch seems to be getting better, so ? When I'm committed tot he gun I may take you up on your offer. Thanks !
