i would like to start casting bullets for my New Vaquero's in .45LC for CAS
i have measured the cylinder throat & they are all .452
should i get a mold for .452 or go to .454?

Get the molds listed as .452664 which is an excellent .45LC bullet although for your purposes the 200 gr LSWC dcesigned for the .45acp works just as well. I size my bullets .452 using soft lube.

The .454 bullet molds were designed for the older .45LC revolver barrels that measured .454 in diameter.

You should size them to your bore, and if the throat is not large enough, it's easy to have it opened up. That's where the 0.454" bullet will likely come into play.
 
Doesn't matter to much what the mold drops as you will have to size to your requirements,.454" gives you more leeway, i have sized cast bullets down from .458" to .452", no problem.
 
it's pretty tough to force a bullet down the barrel
i measured the business end of the barrel (not land to land) & it seems to be .452 also
don't i want the bullets slightly larger than the barrel?

If you are going to cast and shoot your lead bullets in your pistol they must be at least 1/1000 over bore or you will get gas cutting and leading. A bullet sized to .355, the diameter of the barrel, will tumble within 10 yards and cause leading down the barrel. Been there done that. I size all my 9MM .357 for that very reason.

The .452 molds will cast bullets in the area of .453 - .454 depending on your alloy and are meant to be sized down to .452.

When Ben sizes down his bullets 6/1000 he will reduce the diameter of his lube grooves as the lead shears off his bullets. May or may not effect accuracy. Personally I think you are not going to get the best performance out of your lead bullets by doing so but he apparently has not found this to be a problem.

You would be well advised to get a copy of Lymans Castbook Handbook and read it a couple of times. Most of your questions about casting lead will be answered.
