I think all the best options have been stated in this thread. The good thing about the 3 designs listed here, are that they all cast well. I've never tried the hollow point version, but the solid H&G #68 casts easy. The 200 and 230 gr RNFP's cast easy as both solid and hollow points. Is a hollow point mold as easy as a solid? In my case, I can make that said NOE 452-232-HP as a hollow point, or a solid, and I can't tell any difference. My last time, I cast about 500 of them hollow point, and it was just as easy as anything. The caveat is that I know exactly where to run that mold, and I've used hollow point molds plenty. I don't know how much a learning curve would effect this.
I will say this, the solid version of a bullet is never more difficult to cast than the hollow point version. I don't think you will be out anything using two bullets. 45 acp is very forgiving, unless you change something dramatically, most loads hit pretty close to the same POA. This is a complete contrast to something like 357 magnum, where a 125 grain bullet could hit 2' lower than a 180 grain bullet. Lee makes a few good designs in their 6 cavity molds, and despite what some claim, their molds are great, they will serve you well.
