To accurately calculate the coriolis effect on high velocity projectiles at distance for long range data verification,
To get a better understanding of the effect the boat tail angle has on stability during transsonic.
If you're doing this without complete 6dof modeling of the bullet, all you're doing is a wild correlation that is going to be misleading at best. And if you have access to good 6dof modeling, why in the world wouldn't you just reach out to the manufacturer directly?
I imagine there are pretty good internal ballistic reasons for not putting a point on the tail end of the bullet, mostly due to pressure. Essentially you would end up with less surface area in contact with the barrel, which leads to problems with concentricity and weight distribution of any given bullet, and less of the bullet to obturate against the bore of the rifle, which increases likelyhood of pressure blow by. Nevermind that sort of bullet shape greatly affects sectional density, and so you'd have to spin the bullet much faster for a given bullet weight, and then you get into bullet construction issues. Add to all that, that a tail heavy projectile significantly improves flight stability. I don't think manufacturing is the issue, I just think it would yield poor results in practice. As if to prove the point, the short range match bullets with the best performance are flat base bullets, not boat tail designs.
Thank you!
My google-fu must be broken this is what I was looking for. Thank you very much.
Might be interesting encased in a sabot. Otherwise it would be difficult to get them to obturate in the bore and I'd have no doubts that velocity would be terrible compared to other BT bases.
