With all the talk about throat issues with the .45 Colt, what should they slug out at? Is it consistency or size that's the problem?
Thanks for all the help and replies.

Rugers are often undersized (.449-450) with barrel groove of .451+.
This can be bad ju-ju for cast bullets.
Ideally, .4525-.453 where one would want throats today.
Some Colt and Smiths of yesteryear had up to .457 throats and .450-.451 bores in 45 Colt. Two of my very fine shooting 45's have this "problem".
Granted, SAA 44 Specials were not uncommon to have .434 throats and Colt used .427 44/40 barrels, so its more of an understanding that your bullets should fill the throat, dies may swage your bullets during seating these over nominal dimensions, all of which can harm good results.
Bear in mind also that Colt had .356 throats on a lot of 38's and .357's with .357 groove barrels and Smith DX's often slugged .427 with .429 bores so its common to run into discrepancies across the board.
