Dilemma, what do you suggest?

I am in a dilemma.
The firearm is a Ruger Vaquero 44-40.
The barrel slugs .429.
The cylinder throats are .424.
Using the a pin gauge, the neck chambers are .444.
A case loaded with a .430 bullet is .443.
That leaves .001 for expansion.
I believe that is way to tight to release the bullet without excessive pressure.

1. Do I call Ruger and ask them if them will fix the cylinder?
2. Do I call Manson Reamers and see if they will make me a pilot .424 for my cylinder throat reamer. The tool came with a pilot .427 and the cutter is .430.
3. Anybody have a better idea of what to do besides selling the darn thing?

I can not imagine I will get any accuracy from a bullet squeezed down to .424 in a .429 barrel.

Any suggestions would be greatly appreciated.

That was a well known problem with the 44-40 Vaqueros. A friend had one and Ruger did fix the problem, but that was years, ago. No idea what they will do, now, but a phone call is cheap.

This is a well known problem of the early Ruger 44-40 cylinders as NC Gal posted before me. When the 44-40 Vaqs were in production, Ruger would replace the cylinders with new cyliners that had the correct throat size. But they no longer have 44-40 cyls in inventory.

1. You can call them and see what they say now. But I don't think they can help.

The simple solution is to have the throats reamed larger and load/shoot 44 spl/mag bullets sized .429" to .431".

2. "The tool came with a pilot .427 and the cutter is .430." Sand down the pilot to .424" and cut your throats to .430". Or remove the pilot if it's a floating pilot. The chamber cutter will keep the reamer centered.

What size is the chamber cutter, .444"?

Once you open the throat to .430" you won't have to worry about over pressure at the case neck. You'll have the desired nice tight chambers of a custom cylinder for maximum accuracy. Instead of slightly oversized chambers of most production guns. And it will help preserve those notoriously this 44-40 case necks from over expansion, for reloading them over and over.

Hi Hondo44 and North Country Gal,

I do not have a chamber cutter.
I just tried to measure the cylinder in the neck area with a pin gauge.

I was under the impression that I needed a pilot to keep the throat reamer centered.

Isn't .001 clearance awful tight in the neck area?

Thanks to both of you.

Hi,

What did this mean: "The tool came with a pilot .427 and the cutter is .430."?

Yes you normally need a pilot on a reamer. But using a reamer in a chamber of the same size will center itself.

If the ammo chambers, the neck is not too tight and the bullet can exit safely.

You might be thinking of the shoulder in the chamber. If the shoulder is not deep enough, the crimp can't open.

Since you didn't buy a tool yet, just ream the chamber throats and problem solved. You can do it with a power drill, wood dowel and 400 grit paper, thru the back of the chamber. Or send it out for throat reaming.

Or just shoot it like it is if your not shooting competition.

Hi Hondo,

Let me back up and explain.

I have a cylinder throat reamer for 44 caliber. It is .430 and it has a floating pilot for .427.
The pilot is to big to fit in the cylinder throat of .424. My original thought was to call Manson Reamers and ask them if they would make a .424 floating pilot.

I was hoping you had another idea.

It just galls me when something isn't right. Besides, I need all the help I can get shooting. Old eyes don't help. LOL!

Ok, got it, thx.

This is easy then, you have everything you need.

Chuck up the reamer in a drill press if you have one or in a hand drill and clamp it in the vise. Use a coarse crocus cloth strip like a shoe shine rag and cut the pilot down to .425". Polish it down to .424" with fine crocus. Then ream the throats. Piece 'o cake!

Thank you bwinters and Hondo,

Thank you for the advice.

There is no hurry because I don't have any 200 gr. bullets on hand. I forgot to order some. The Starline brass showed up, so I remembered part of what I needed. Old age sucks. LOL!

Hi Hondo,

I called Manson Reamers this morning and for $10 they will cut a floating pilot for .424.
That way I do not have to ruin my .427 pilot.

Just an FYI, they also have a 41 caliber cylinder throat reamer in stock. I could not find one anyway else.

Have a great day and again, thank you for the advice,
Keith

That's great! Sorry, I missed that part, it'd be hard to polish a floating pilot!

For $10, that's the way to go.
