I did a SS Ruger .45 Vaquero, 4 5/8".
Why? After reaming the cylinders, it still shot patterns. Smaller pattern but still patterns. On average, it shot about 4" low. I started to file the front sight.
Then, after studying up and reading about Taylor Throating, I decided to try it.
Not only did the groups tighten relatively dramatically, it now shoots to the point of aim and makes me glad I didn't file the front sight more. Typically shooting 250g Leadheads, Beartooth, or similar Keith type cast bullets with mid to high levels of Unique or 2400, I can record 2-3" groups at 25 yards. This is very good for me.
It helped this gun and based on what I have heard and read, it never hurts and mostly helps. This is just one guy and one gun. Your mileage may vary.

Just curious, what is the difference in the Taylor throat and an 11 deg. throat?

From Jim Stroh's Alpha Precision website: www.alphaprecisioninc.com/revolver/default.htm"Essentially, the barrel throat is lengthened one and one half to two calibers, and enlarged to slightly over groove diameter. The throat serves as the throat in a rifle barrel, enabling the bullet to become perfectly aligned with the bore before engaging the rifling. The "choking" effect present from tightening the barrel into the frame is removed as well. The rifling leade is a very gentle 1 ½ degrees. On average, when tested before and after using a Ransom Rest, 50 yard groups have been reduced 40 to 50%. The improvement is there using both cast and jacket bullets. I have not detected a change in velocity using cast bullets. Before and after chronographing is within standard deviation of each test. Using jacket bullets, there is a slight loss, less than 50 fps in all the tests I’ve conducted. If the barrel cylinder gap is adjusted to minimum at the same time the Taylor Throating is done, there will not be a velocity loss with jacket bullets, usually a gain of 25 to 50 fps. I am convinced Taylor Throating produces the greatest accuracy improvement value available. Line-bore chambering will produce the most accurate revolvers, but the cost is prohibitive for many. When the barrel is accurately recrowned; the forcing cone recut concentric to the bore; Taylor Throating is almost as accurate as line-bore chambering with a savings of several hundred dollars." |

Taylor Throating has never hurt a gun as far as I have ever heard. It has helped alot of guns and I had one done once. You still have to pay attention to barrel choking when doing the process. I once had a gunsmith talk me out of Taylor Thoating and just letting him cut a long low angle forcing cone. I wasnt sure about the whole thing but let him talk me into it. It was done to a 7 1/2" Ruger Bisley 357 barrel That wasnt quite comming around. As far as I'm concerned it worked as well as Taylor Throating. The gunsmiths thought was you sometimes have to go back and forth to get the correct throat dia. because of barrel choke and the long forcing cone would be large past the threads. When the barrel was mounted on the frame it was done with minimun b/c gap.

Gary Reeder wrote about it in the last few weeks... He said something about it predating the heavy bullets we now shoot so much of and that his variation of Taylor Throating (Maxi throat?) was better for the big bullets...

Axe, when you say Gary's variation of Taylor Throating how does his version differ?

Just curious, what is the difference in the Taylor throat and an 11 deg. throat? The forcing cone is the first point at which the bullet enters the barrel from the cylinder. Think of it as a funnel of sorts. I forget but I think the standard is about 8.5 degrees. 11 degrees is wider at the bigger end and is believed to create a gentler transition from the cylinder throat to the barrel and is thought by many to be optimal for cast bullets. Taylor Throating is the section of the barrel immediately past the forcing cone (and is well described in the text from Jim Stroh's website listed above). That about right guys? |

Yep. I have Jim Stroh building a tight 5" 45 Colt from a beater S&W M29 I picked up and it will have a Taylor throat.

Can anyone recommend a reamer manufacturer/source for the home DIYer?

Brownells sells kits for (I think) 11* or 17* cutters.The cutter plus handle & extension. "BROWNELLs Chamfering Tool Kits". Ther are several kits according to caliber.I have the 22/32 and 44/45

Something in the back of my mind tells me that Brownell's doesn't carry the Taylor Throating reamer any more but it is available directly from Manson. I think Box is right too that the reamers you've referenced are forcing cone reamers.
Bowen had an article recently (in Handgunner??) that discussed the Manson reamers. It appears that the current reamers have a very nifty poly / plastic sort of guide and spring set up.
I Taylor Throated a Vaquero 45 with good results.
