I’ve already got one in the works. I’ll have a range report and ballistic data when the cylinders come back from reaming. May I ask whom you found to do the reaming without having to send the whole gun? Not sure why anyone would ever need the whole gun? Nobody I’ve talked to wanted the whole gun. Harton has done a few for me and didn’t need the whole gun? Who do you use that requires the whole gun and why?

If it's just deepening 357 Magnum Chambers, I'm also unsure why anyone would need the whole gun...

Can a guy safely ream a factory ruger full sized NM Blackhawk cyl to fit 360 DW brass? I am sure you would need to be bit choosey with bullets, but hell, fun is fun. ...tj Huey is totally right TJ. The cylinder is to short. You can deepen it but completely defeats the purpose. Cylinder needs to be considerably longer if you are going to utilise extra case capacity and longer nose area for longer and heavier bullets which is what the 360 was designed for. More OOOOOMFFFFF. Now the Redhawk is a different story. Ive Built 3 of them ( 360)DW on factory cylinders. Really brings em to life

If it's just deepening 357 Magnum Chambers, I'm also unsure why anyone would need the whole gun... Even if going to another caliber, why would they need the whole gun? If going to a different caliber, I'd either send the whole gun or be very selective about who did the job. If going to a larger caliber, I prefer line boring. Of course, not necessary with all guns. But, still my preference. I try to keep the gap behind the cases at .003-.005". Since case specs and reality aren't always the same, I either measure or request the smith measure. Clements trusted me when he cut several of my 45 Auto Revolvers for Auto Rim. I'd do the math and he'd cut to my requested depth. I'd shoot for .004" clearance and we were never more than .001" off. I believe that was due to brass variations. I realize that's OCD, but both Clements and I are stricken with it. The process worked for us...

I found Starline 45 Auto Rim Brass to have rims .002-.003" thinner than Remington Brass.
While I use Remington Brass in my S&W 25s, I had my Customs cut for Starline Brass.
I can still use Remington in those chambers, but cannot leave a primer even a little proud.

If it's just deepening 357 Magnum Chambers, I'm also unsure why anyone would need the whole gun... I know some wish to verify safety, timing,etc. for liability reasons should things go wrong. There's also a matter of reproofing the cylinder after rechambering. Again to appease the lawyers and to cover one's self.

Unless that ratchet is altered or the lock notches move, timing can't possibly change.
But, I do know gunsmiths who request the whole gun.
I usually discuss my ideas with Clements and Huntington. I've learned to trust their counsel...

If you are a hobby machinist you know a reamer is following the hole that’s already there unless the setup is way wrong. Id also seriously doubt anyone is sending their work out to be proved and them just saying they ran “xxx proof” load through something before sending to a customer would hold zero water with an attorney or a court.

I texted Jack and he too recommended the BFR if I pull the trigger on this project.
If I decide to go thru with this one, it'll be a simple build.
Rechamber the cylinder, open throats for cast bullets if necessary, etc.
Cylinders measure 1.850" long in my BFRs. As Ronnie stated, this is the key.

I see a lot of the BFR’s cylinders are measuring 1.850-1.875 or so. I’m not sure why MR lists them at 1.903? 1.850 should really be able to make the 360dw sing with heavies though! The mp rcbs 200gr clone will be one of the first I try.

I've learned to trust their counsel... It's not that timing changes, rather than it was incorrect to begin with. As I said, lawyer stuff. Do I think it makes a difference? No. If a 42,000 cup load of magnum is safe, then the same pressure DW will be safe. I simply asked who was doing the work. Bowen wouldn't. Reeder wouldn't. Fink's wouldn't. Tyler wouldn't. Etc..

I hear you and agree. We kinda got sideways there because I was referencing Hunter01 being a smith and not needing that stuff checked. As far as my project goes, I'm not yet decided on anything. Just wanted to get the collective knowledge on the forum to offer opinions on feasibility of the project.

Mr. Wells and myself actually spoke about the 360 a month or so ago. Mostly about it in the Redhawk.
My experiments with it have been in the Maximums. My loads have been tailored for accuracy more than top velocity. The only reason I got interested was five pieces of brass in some 357 range brass I bought for cheap. I've got about 35 now in hand and am backordered for 1000 more with Starline.
This summer I intend on getting both a Redhawk and a BFR to rechamber.
I will also get an extra cylinder for the 353 to do when it goes back for the firing pin upgrade. It's simply too accurate (even for an FA) for me to mess with the current one. I'll never shoot 1/4" groups from anything other than the Ransom Rest, but it's nice that the gun is capable, even if I am not. And that's with full power Sierra 170's on a bunch of #9.

Hope you keep us posted as you move forward with your projects.
I completely understand your "too accurate to touch" problem. I've been there plenty of times too.
Ronnie is well versed in the extended length cartridges and there's no finer revolver than Freedom Arms.
