Howdy men,
I've posted on this topic before, however I now have more information than I did previously.
Cylinder Throats: .430 (Maybe just a tad larger according to cylindersmith.com)
Bore Dia. I slugged the bore several times just to make sure. A soft lead slug driven in from the muzzle. To the utmost of my abilities, I find that I have a .430 bore.
(Okay, I know this is almost an unheard of thing. Cylinder throats and the bore dia. matching on a stock S&W handgun. But, it is what I have discovered).
I've done a great deal of reading on this topic the past several days, and have yet to come to a conclusion if this is a good thing or a bad thing. Both the cylinder throats and the bore dia. being the same.
I plan on shooting Lyman #429421's and a host of other cast boolits through this gun. A S&W Model 29 with a 4" tube.
I will eventually be looking for a 'mid range' load for it. But for now, will need to be working up some full power loads for hunting season.
Experiences?
Suggestions?
Many Thanks,
Murphy
