which dimension
« on: December 15, 2003, 11:17:13 AM »
I've been doing alot of reading -- so here it is.  Some people say to size your bullets .001--.002" above groove diameter.  Some people say the bullet has to match the throat diam. to be accurate.  If the throat, theoretically of course, is .460" and the groove diam is .457", what size do you go with?  What do you size? :-D

I lean toward sizing as large as the gun will chamber easily if a rifle type, or to slip easily through cylinder throats of a revolver, making sure the throats are at least as large as groove diameter, enlarging them if necessary.

Simple enough?
