I am about to purchase a .22 cal mold and have decided to give the RCBS 55 SP design a try. RCBS is my favorite commercial brand and NOE does a fabulous job as well.
I have never cast 22 cal before and wonder about cadence and mold heat retention. I figure that brass and iron would help with heat retention given that such small boolit cavities won't be providing as much heat to the mold as the 200gr+ boolits I normally cast for.
I'm not too hung up on the 2 cav issue if I go with RCBS and am currently considering the 3 cav brass mold NOE has in stock (I think a 5 cav brass would be too much of a good thing weight wise). One thing that NOE has in my favor is I can buy a Saeco style top punch for my Lubrisizer to go with the mold. RCBS is obviously a cheaper route though.
Could use some help from the experienced here. Am I off base with my heat retention thoughts? Do I abandon the brass and iron and just go 3, 4 or 5 cav aluminum? Any reason to pick one brand over the other?
I am in need of some guidance!
