i'm working on my ruger vaquero and i'm fitting a new cylinder to the gun. the cylinder i got is 44mag cal and i will be reaming it to 45 colt. but i want a tight chamber so i was thinking about using a 460sw reamer and just control the depth. does any one have a 460sw or a 454 casull or even a 45 colt reamer that would let me barrow.
That's a stretch with a finishing reamer, but it will work if you're careful. Just get a Manson from Brownell's and be done with it. I think the .460 is an excellent choice as far as "correctly" sizing the chambers, expecially in that gun where you won't have to worry about a rim recess. If you were doing a rifle, you might have to get creative.

i'm going to be milling out the chambers first. i will measure each chambers location in reference to the bore then i will program the mill to cut the chambers to the correct location if thy are off. that way i can just use a finishing reamer to take it to size. so you think a 460s&w chamber would be better then a 454 casull? i cant seam to find a 460 S&W reamer to buy, but there are lots of 454 casull's.Quote:

JT, it all depends on what you will be shooting in it. Personally, I don't like bore-riders in a revolver, I like the large, fat, ogival nose to poke out almost flush with the end of the cylinder and be supported by the chamber mouth. I don't like a huge freebore in a revolver, but I do like a long, tapered throat that can be stuffed with boolit, so it's supported better during firing and is as close as I can get it to the forcing cone. A short throat with a sharp angle is designed for SWC boolits or others with a sharp front band and a reduced-diameter, short nose, and the front band is supposed to be out of the case and just nearly touching the throat. I think that gives a pretty sorry start in life unless you have a really tight chamber to keep things lined up while under the force of gravity. That also is a recipe for the maximum jump to the forcing cone, which seems to promote skidding.
YMMV, you may have different experiences that give you different opinions on what works best in a revolver, in fact many approaches work when fitting boolits to revolvers, it's just a matter of which way you like best.
That's why I say the .460.
