...or maybe a .359 or .360, from what I've hears some say after slugging their bores!

There was a post on 'slugging bores' that was up last year, and when I went to slug the .44 Magnums I have, I got .430's, .431's, .432's, and one .433 - the only sizers I have are .429 and .430, so I stalled out on the casting thing, unless I can get a Paco's Accurizer to bump my .430 bullets UP a bit.

From what I've heard, some of the .357 guns are likewise very overbored.

You will only know what to size your bullets for your gun after you slug that bore. Add .001-.002" to the groove diameter to start. Anything else is guesswork.

Pure lino is hard to come by here. It makes a dandy addition to softer alloys to bring them up a bit in hardness and make them more suitable for water quenching.

In a perfect world, you won't need to size at all. A little tumble lube a load em.
Kind regards,
