Yes. the boolits are very similar to 303guy's.
They are smooth sided and usually one or two diameter boolits. For PP boolits, I make cylindrical moulds and for "naked" boolits I often use two diameter similar in design to the Lyman 311299 but of course no lube grooves. I knurl to allow lubing.
There is a copy of an old Ideal catalogue page here:

I make mine from 1 1/2" round bar so little more robust than the Ideal. I thought I had invented something new when I came up with the idea back in the 1960's but apparently Ideal beat me to it by about 100 years (maybe not quite).
