I ordered a sample pack of some 230gr cast lead bullets from Badman bullets. I had some concerns over how they would stabilize but it worked great. Accuracy was slightly worse than the 190gr bullet I had been using but I think terminal performance will be better. Loading them over 5gr of HP38 for about 1000fps, very quiet in 357 SBR rifle.
230 vs 158hp
50 yard group looked like this, slightly lower POI than the 190's. Dot is 2"
