Taylor Throating vs. Chamfer Cutters

[Capo]

Hello folks,

I have a S&W 627 with a forcing cone that looks like it's been factory shaped with a wood rasp. The grooves in the cone are pretty deep and leading with LSWC's on the cylinder face is heavy.

Current accuracy is okay, but I'd like to get as much as I can out of this revolver. My Colt shoots better than this particular S&W.

After some web searching, it looks like I can rectify the cone with either chamfer cutters or with the Taylor Throating reamer.

Can anyone provide a recommendation on the preferred alternative?

Also, does the 627 have a specific forcing cone angle that I should stick with (i.e., 11 vs. 18 degree, etc).

Thank you ... Mike

Either one should solve at least part of your problem. The Taylor Throating essentially leaves the portion of the bore inside the frame smooth - it removes the rifling - to relieve any constriction there.

It is very common for the threads in the frame to slightly constrict the bore. This constriction swages the bullet down to allow it to pass, leaving you with a now undersized bullet to rattle down the bore. Taylor Throating eliminates this.

If you're only concerned about doing either of these operations to one gun, it would probably be more cost effective to send your gun to a good smith and pay him to do it. The Taylor Throating reamers are caliber specific; the forcing cone reamers are not, but the kit is still rather pricey.

Neither of these operations is very pricey when done by a gunsmith - it's the shipping that will get you.

If you feel its a manufacturing flaw(sounds like it to me) , call Smith and let them fix it. It is a Performance Center gun (I think all the 627s are), you already paid for the gunsmithing.

Thanks for the reply guys.

Yes, it is a PC revolver and I guess it's a manufacturing flaw – not sure. Based on previous experience with S&W, it may be within their acceptable specs. In any case, I'm reluctant to send anything back to them because of poor craftsmanship. I.e., a recent barrel replacement came back with a new barrel with a bulge on the outside (poor machining or grinding) and a forcing cone that was off square with the cylinder face by .002".

I considered a gun smith but I don't know of a good one locally. And your right, shipping with insurance is nasty at about $70 one-way. The idea of buying the tools, doing it myself and reselling the tools here (or e-bay) to defray costs might be reasonable.
