Looks like a high BC bullet, but doesn't look like it would be good on game unless you went for bone. Looks like it would pencil like a Barnes would at BP speeds.
I don't have a CAD program though or the software to estimate stability or BC. Having them design it increases the cost untl R&D has been paid. Another option is...can the Lehigh 215 CF be made from copper instead of brass. In copper it should be very close to 220gr. :D |

If i had the funds and still had a strong desire to shoot sabots, i would like one in 220gr, larger HP and a polytip from their Raptor line of bullets.

The CEB 240gr ML bullet is copper. Many of their other bullets are brass though.
Can you ask Lehigh for an estimated weight of the 215 CF made in copper? That might be the ticket without a ton of additional R&D costs. |

GM, I'm no metal engineer but I'm thinking that Dave used the brass for control in opening. Copper being softer would probably require a lot of rethinking on the slits and such for the controlled fracturing. Correct me if I'm wrong on that assumption as my metallurgy knowledge is geared more to steels than heavy metals.

Lehigh currently sells some CF and Maximum Expansion bullets in copper. http://www.lehighdefense.com/collect...led-fracturing

Yes but not THAT particular profile. As I said, I'm thinking he used brass for it's strength for a more controlled opening.

Well that is what i would like to find out. How well a 215gr CF would work in copper and how much it would weigh in copper. Lehigh also makes a Max Expansion 308 in copper.
Im not locked into the fracturing requirement. Expansion is fine with me also. My FPS window is huge. I can shoot them pretty much as fast as i want or as slow as a 10mm carbine. Ive shot a 225gr Barnes so fast it kinda fractures and the energy dump was impressive. The recovered bullet still weighed around 200gr. |

The 200 grain bloodline performs great. Something with that performance but just a little more weight and B.C. Would be great. Even though the 200 grain works just fine for what I do.
