By the time this mold came out is was 32Less. A friend has about 8 of them so I usually shoot his.
As to the blocks, aluminum. I have aluminum, cast iron and brass and don't see a lot of difference in the quality of the boolits thrown or how long one can throw in a session. I can say that casting with a good quality 6 cavity aluminum mold is a lot less tiring than a 4-5 cavity brass or iron.
