Slugging Pardini .32 ACP barrel?

I thought that they didn't melt in your hand. The next thing I know someone is going to tell me that it doesn't take 3 licks to get to the tootsie roll center of a tootsie pop.

I'm surprised Chris didn't mention it, but just holding the slug in your hot little hand will change the dimensions. Just tack that onto your "WAG".

CTE of lead is 15.1 x 10^-6 in/(in F), so a 10 degree change in temp for a 0.314" slug will change the diameter by 0.00004". Given the other errors, probably not enough to worry about.
