After casting about 100 bullets from the mold, and running them through the lubrisizer, I weighed them they all weighed in the 270-273 gr. range. My alloy was mostly a lead and babbitt mixture that cast well and was mighty hard. I'm trying different loads now ane maybe will actually get a chance to shoot some of them soon. If I like this bullet, I'm going to sell my Lyman 452490 and handles.
