Just bought a box of Barnes XPB Pistol bullets. One of the gays at Banes said this would work through a 454 Casull. I have been loading 265 grain hard cast lead, but I want to speed things up and get a little more range. Freedom Arms load data tells me I can take a 240 grain JHP with H110 with 39 grains of powder. Any ideas on a starting load for a 200 grain bullet? Anyone with ideas or experience...would appreciate help!
