Recently I bought a Lee 225-55-RF GC two cavity mold with the idea of using it in my .218B as well as my other center fire 22's. And after casting some in my standard alloy of WW + some type for fill out, I found that the nose is way too large for the bore of the B as well as the other center fire 22's that I have,- .223". They need to be a max of .219” or maybe .220 so that I could size the nose down. with a NOE .219” nose bushing.
The other mold that I have for the B is an NOE 225-60-RN PB that drops a bullet with the nose at .220". I then milled .065” off the top so that now the bullet length falls under the upper length limits of the 12” twist according to Greenhill. And size the nose down with an NOE.219” nose bushing. This combination is shooting well in the Contender, Averaging under an inch for five at fifty so far.
And trying to size the nose down .004” doesn't work, too far. Thought of a different alloy but doubt that there would be that much difference. Right now, the mold is useless to me. Still undecided whether I will contact Lee or not. With the cost of the mold plus postage back and forth, probably just throwing good money after bad..
The question is... For those of you who have and use this mold, Do I have an exception or the rule with this Lee?
