I have bought cast bullets from Oregon Trail (LaserCast) that are hard enough to shoot at jkt velocities in my GP100 Ruger. Have used the 125 and 130 trunicated cone and the 158swc's but the best accuracy that I've found with my gun is with the 180grn True Shot bullets with max loads of LilGun. The odd thing was in my revolver the 125's were a little more accurate than the 158's before I tried the 180's. I'm now trying to cast some hard cast of my own with a Lyman mould in 170grn. BM

PS: edit-One secret to no barrel leading is having a well broke-in smooth barrel. My .357 used to lead up more when it was newer but it's half wore out now and shoots lead bullets better than jkt.
