kevinj308 Posted February 8, 2012 Share Posted February 8, 2012 I decided to change the 4" barrel on my 625 for a 5". Now that I'm getting ready to order the tooling from Brownells looks like there's some choices to make. 11 degree or 18 degree forcing cone? Does it matter? If it matters I shoot lead, Bayou Bullets coated these days. Thanks for any thoughts Kevin Link to comment Share on other sites More sharing options...
Toolguy Posted February 8, 2012 Share Posted February 8, 2012 I use the 11 degree one. I like the idea of a lower angle on the taper. It is just personal preference though. There is no "magic angle" for the forcing cone or muzzle crown. Any one that is exactly concentric and smooth will work fine. On the forcing cone there is an optimal range of diameter for the opening, but otherwise not real critical. The 18 degree one will work just as well as the 11 degree, assuming both are done right.

kevinj308 Posted February 9, 2012 Author Share Posted February 9, 2012 Thanks, I was kinda leaning towards 11 degrees. Kevin Link to comment Share on other sites More sharing options...
z40acp Posted February 9, 2012 Share Posted February 9, 2012 (edited) Get the 11 degree. I had a 629 that shot JHP very well but cast lead not too accurate. I used a kit from Brownells and changed and also smoothed up the forcing cone. It made a very big difference with the size of the groups. Rugers always seem to like cast boolits and some of those I think are 5 degree. Edited February 9, 2012 by z40acp Link to comment Share on other sites More sharing options...
