Savage 458,

I ordered the 6.5x57R finishing reamer from PTG. It is an excellent, super-sharp tool, but the throat that it cuts is so short that I could not fully chamber rounds loaded with the 140 grain Nosler Partition. I had to buy a throating reamer from them to rectify the problem

Best,
Ron.

PS: Would anybody out there have a .32-20 finishing reamer that they are interested in renting out or selling? By the time I buy a new one and pay shipping and taxes, I'll have spent $150.00 or more for a reamer that will cut those two little chambers and then never be used again.

Ron - it probably is of no use to you, but I do have a .17AB reamer with adjustable pilot. Unfortunately, it would cut the Ackley Improved chamber and you would need a neck-throater to finish the chamber. Too, you would need a bore sized .32 pilot to make my reamer index in your barrels.

It cuts a minimal web size which may or may not fit .32/20 brass.

There are a couple of places here in the states that rent reamers, have you tried them? Not sure if they will ship to Canada however,.

Daryl, Unfortunately it would cost just as much that way.

Despite not having posted here for a while, I have been working away at the third set of barrels. I obtained two 1910 Ross barrels, turned and polished them, and fitted them to my other mono-block. I also fabricated and fitted a bottom rib and front swivel base. Today I finished the fitting and polishing of the extractor that I made up. Now i have to wait for my .32-20 chamber reamer to arrive. Then I can cut the chambers and take the gun out to proof-fire it. The photos show the original .410 barrels on the right, the 6.5x57R barrels in the centre, and the .32-20 barrels on the right.

Looks great Ron! Mind if i ask about using the liquid nitrogen to shrink fit the barrels into the monoblock. Do you simply submerge the barrel tenon into the LN? How long do you leave it for? Is the barrel then tapped in, or do you use the threaded rods to "draw" the barrel into position?

Matabele,
When you lower the barrel into the liquid nitrogen, you get a whistling jet of white nitrogen gas spewing from the muzzle. That is because the warm barrel is changing the liquid into a gaseous state at a very high rate. You need to wait 5 or 10 minutes until this ceases. That tells you that the shank of the barrel is at or near the temperature of the liquid nitrogen. Wearing heavy gloves, remove the barrel from the thermos, drop it over the threaded rod and ensure that the shank drops down into the monoblock. Drop a washer over the top, thread a nut down TIGHTLY, then wait for the temps to normalize. That's it!

Thanks for the explanation Ron, seems a really simple process compared to the alternatives! Being such a tight friction fit I imagine the bond between barrel and mono block is as tight as anything.

Ron, your build posts are always a trove of information!
I, for one, really enjoy seeing the build processes unfold and wish to someday attempt the same on my own. A long term plan for sure so I have lots of time to learn from gents such as yourself.
Keep it coming!

Well, the chamber reamer arrived on Thursday. Here's a photo of two snap caps resting in the newly-reamed chambers. I'm now busy at chequering the new forend that I made up to fit all three barrel sets.

That setup is going to be a lot of fun Ron, congrats! Good job on the fit of the extractor too, almost seamless.

To be honest, I did not "fit" the extractor, I only fabricated it. I am fortunate to have a good friend who is a tool and die maker and has a Bridgeport-clone milling machine in his garage. Bill is also a shooter so he understands the "whys and wherefores" of these jobs. Whenever I need a job done that requires a mill, like sinking the mortise for the extractor, Bill is the man I go to. You're correct, he outdid himself on this one. Once I had filed and stoned the face of the extractor flush with the barrels, it was hard to see the seam.

Ron a question,

At the risk of sounding a little dense, how much of the barrel is immersed in liquid nitrogen? Is it just the turned chamber end or the whole barrel?

I immersed about 1 foot at the chamber end, because that's about how much liquid nitrogen was in the thermos.

I finally got out to a friend's farm today and proof fired this double. With the .32-20 barrels mounted it was a walk in the park. My 6.5x57R loads were 4 full grains over maximum listed. The cases showed some scuffing after extraction but nothing else and the gun is tight and on the face after 3 proof rounds through each barrel. Considering that my regulation load is the minimum listed in the Nosler manual, I'm confident that I'm good to go. Time to solder the ribs to the barrels now.

I noticed one problem when I proof fired this rifle yesterday. Because of the large diameter of the shotgun firing pins, and their sloppy fit in the discs, I was getting a lot more primer flow than I can live with. Today I stripped the action down. First I held the pins in a collet in my lathe and reduced their diameters from the original .096" down to .070". Then I drilled out the discs with a # 28 drill bit and threaded the holes 8-40. Then I threaded in 8-40 screws, locked in place with Loctite Black Max, drilled through them with a #50 drill bit (.070"), and dressed them down flush with the discs. A touch up of bluing, reassembly with a dab of blue Loctite, and problem solved!

Great to hear the gun passed proof, and nice solution to the firing pin issue. I'm looking forward to hearing how it regulates and shoots!

Earlier this week I finished soldering the ribs on the 6.5x57R barrels, then spent a day cleaning up the resultant mess of flux and surplus solder. The barrels are now at my friend Bill's place so that he can mill the dovetails and mortises in the top rib for the sights and the scope bases.

Below is a photo of the .32-20 WCF barrels. I have tinned all surfaces with Hi-Force solder and acid flux and scrubbed away all residual acid afterwards with hot soapy water. I then coated all mating surfaces with liquid rosin flux and have it clamped up in my jig ready for final soldering. Now I find that my oxygen tank is empty so completion will have to wait until Monday.
