To much time

[harrymoreland]

Hello all , Off work as I am my mind has time to wander, and so a thought (of sorts) entered it. Please be gentle.

Would a projectile shaped not unlike a V ( > ) work, not work?.

No waist to cause disturbance.

Weight forward of centre, ala shuttlecock.

Skirt thin enough to expand into rifling.

Lot's of details would need to be sorted out. Most slugs have a hollow point to help with expansion since their tips are more pencil-like than pellets. With pellets, that's not as much of a concern since they've got such a large face compared to slugs that they still distribute their energy fairly impressively. With a projectile like you're describing, it might have some merit, but there's a lot of uncertainty. For example, with pellets, you have two bearing surfaces, the head and the skirt. I don't know how removing the head bearing surface would affect the internal ballistics. Regardless, a shuttlecock still has a very high-drag shape because of the skirt, so the ballistic coefficients may not be much better than pellets.

+1 the above. A V shaped bullet would not ride in the barrel with any kind of consistency. I am no aeronautic engineer, however, I see a lot more drag from the simple v shape than I do from the diabolo shape, with severe turbulence vorticies behind the tail.

That is priceless. I am SO using it.

Might be hard to keep it spinning on its axis. Might be a wobbler.
