Because my sizing die is .452. I've always had trouble with my 38's and 44's and my sizes are .358 and .429... I think it's time for some new, larger sizers. I know Versi has always said to go a little over to reduce leading but I didn't know this 27 years ago when I was getting all my casting equipment. I must have gotten lucky the 452 die because I didn't fit it that size on purpose. No idea why that happened... Anyways, I think I'll get a 359 and 431 if I can (Lee sizers, I like them better) and see what happens.
