I have a new one that looks like all the others. I haven't found a good lead (.431) load yet. The plated bullets (.429) shoot better, and the jacketed bullets (.430) shoot the best. I ran out of jacketed but they started to group @ 100 quite well. on my next order I'm going to get 180, 200, 240, and 300g. If I find something especially accurate I'll post it. The bore size is a solid .430 to .4303. Most 44 bullets are .429 but Hornady and Remington both make .430's.
