Excuse me for my ignorance but I have just started using Lyman moulds for my 45/70. I recently puchased a used but like new mould from a fellow member who put it up for sale as a Lyman (457125) and was just informed that unbeknowest to him, it was a Ideal mould. I know Ideal was the forerunner of Lyman.... my question is why are they held in such high regard ? Are they of better quality ? Thanks in advance !
