Golfsw.... great web name!!! Gave me a chuckle!
Larry's advice and good advice it is...I find casting solids a heck of a lot easier than HP's, even with Mihec's excellent multi-pin molds. Too, at least in my examples, the solids are a bit more accurate. Here on our farm, solids work for everything...plinking, vermin (possums and raccoons) in the horse feed bins, and rarely, putting down injured stock.If plinking and general shooting at targets or even targets of opportunity then the solids suffice. For the magnum level loads I cast them with 16-1 alloy.
Lyman's 358156gc or nude, works well and is a smidgen more accurate than the MP version. At former FBI revolver load levels (158 gr HP's @ ~950 fps from a 4" bbl.), it's a do-all combination, and my personal, day to day favorite. I use it in a cpl of M66 Smiths, a pair of M19's, one M60, a Ruger Flat Top and my Marlin 1894CS (this last sized to 0.359+" to accommodate Marlin's Micro-Groove rifling). Revolver loads, BTW, are sized to 0.358" and are cast from ACWW's with annealed Hornady GC's seated. If casting HP's, I use a 50/50 Pb/WW alloy to enhance expansion.
