I read a thread on sixgunner about gages that can be purchased to measure cylinder throats. It's a tool used by tool and die makers. Anyway, you slide the gage into cylinder, tighten the lock nut, withdraw the gage and measure the diameter with a micrometer. They range in price from about ฝ.95 - $$$.$$. I found the site of one of the manufactures, Enco, and they have the ฝ.95 one (the same gage on another site cost ุ) on sale for ű.99. It's a four piece kit and will measure diameters from .313" - 6" (just in case you have a six inch barrel...). This is not only a time saver, but also inexpensive, too, if you want to slug more than one gun. Just thougt I would pass that along. The address is: www.use-enco.com. The product number is: 615-6610.
P.S. If anyone has some load data for a 340gr BTB using 2400 in a 454 RB or SRH, I'd appreciate a post. Haven't been able to get any info so far. Thanks.
God bless,
