I bought two brand new, new stock Lyman moulds. One 429421 and one 358429. I was pleasantly surprised that they have went back to the square lube grooves and full bore front driving bands. Cleaned them both up and smoked them. The 358429 broke in after 4 pours....nice. A full .3585 on all 3 driving bands and all 4 holes. The 429 took two sessions to break in, but very similiar results with that mould after break in .4305 on all three bands on all 4 holes.
I used straight ww for the results, no added tin.
PS Only quality problem I noted was the need to adjust the alignment pins by driving them into the mould a little deeper on the 429421. A small thing in my book.

I have both these moulds from 'bout 2002. Like you say, they are great. My 429421 will size .431 from air cooled wheelweights.........Creeker

Heavy Lead,
Was this very recent? And where did you get them? I just ordered one of the 44's from Midway, I hope it will be the "new" change.
Thanks, MAlcolm

Yes sir, just two weeks ago from Midsouth. I was pleasantly surprised when they arrived and I took them out to give them a bath. They are casting fools. I ordered a new 20# Lee Pot with the order too, and I'm glad I did, that 10# er just wouldn't keep up. Now I wish I could find one in the 454424. I did modify the Lyman handles for both. They don't open far enough IMO for the cavity closest to the hinge, so I took them apart and went to work with a hacksaw so they would open up a little farther. Probably didn't need to do this on the 358, but I needed to on the 429.
