Nick,Do you like the Rabbit Magnum II design any better? I think the Nomad pellet making kit is a similar shape. I've attached a picture of the Nomad pellets.I see that the Piledriver longitudinal splines are to reduce the contact with the lands and make it easier to push or load in the breech where as the nomad has full contact. Plus the Piledriver had the boat tail.As always I defer to your expertise as I am not a bullet designer or tester of what works. I don't comprehend the other projectile factors you guys are mentioning i.e. center of gravity etc. So I'm trying to learn. Taso
Taso, I just took another look at the Kolbe Twist graph you posted in your first post.... You forgot to put in the boattail length, so it may be out of whack....Bob
