I was reading an article in an old magazine this morning about which bullet shape is best.
Well, in the mind of the author, it depends on velocity and what the bullet is used for.
This magazine was appx 40 years old, and David Tubb was quoted a few times.
The main reason for the article was the more prevalent availability of Low Drag and Extra Low Drag bullets and folks using them for hunting in situations which they weren't suited to.
It was mostly concerning DRAG and where on the bullet it had the most effect.
It also went on about how well the bullets expanded.
Apparently appx 70+% of the "drag effect" on bullets which are SUPER SONIC is on the base, with the rest accumulating from a point on the OGIVE, rather than the tip of the bullet. It's not until a bullet goes SUB SONIC that a "pointy tip" with an extended ogive start to reduce drag significantly.
Likely that's why boat tail bullets came along first, as most folks weren't worried about drag beyond 300-400yds. The boat tails created a "slip" for the drag to diminish.
Lots more to the article but this was pretty much its basic point for being written.
They did tests with different ogives and found that a pointy tip, although stimulating, didn't really do anything until the bullet went subsonic.
