Beautful, the expansion on the last one is exactly like the Barnes X bullet. Lets see what they will do to 100 and 150 as far as accuracy. If they hold up you have a low cost alternative to Barnes.

Low cost and machining anything in small quantities are mutually exclusive. It would have been much cheaper to go out and buy some Barnes. I originally made this as a boattail, but after talking to some of the folks here it seems like boattails and standard sabots don't work well together. I wonder is there is way of getting my hands on the yellow MMP sabots used in the TMZ and Spitfire. I may just end up going to a flat base design, but keep the nose profile. This is more of an engineering/fun (I am also a Mechanical Engineer) excersise than anything else. I just wanted to see if I could get it to work. Getting the 6 petal expansion required making a hexagonal punch to score the inside of the HP cavity. The bullets were annealed at 900F for30 minutes. Lee my target weight was in the 270-290gr range. Since I used CAD software to do the design I was able to dial it in fairly close. I figured heavier is better especially at MZ velocities. The bullet is intended for game in the Hog/Deer size range so I wanted large diameter expansion and moderate penetration. A far as getting fired, I work for my dad in his shop so the likeleyhood is high;).Thank you all for the positive feedback.
