Make your own, like these I made;
Those are 44 mag 310 grainers.
Those are .45 200 grain RNFPHP.
That's the mold, made by MP molds in Slovenia by Miha Prevec. It's a cramer type mold that allows the HP pins to stay with the mold. Keeps them hotter to make nice filled-out HP boolits. The pins can be turned around to make a solid.
It's a group buy from http://www.castboolits.gunloads.com/
The wait is around a year, but he makes some extras which he will sell to the public. Cost is $150.00.
No 38 hp's----------YET. waiting on a mold that is a copy of the classic 358156 in HP configuration,(158 grain as a solid, should cast at 145 grains as a HP).
All right I did see you want to buy ready made bullets. I just had to show you could make your own, and how mine turned out. And yes they actually expand well and are very accurate.
