Let's talk TRANSONIC!

[Distant Thunder]

Because the transonic range is generally said to be from 1350 fps to 900 fps ( Mach 1.2 to 0.8) and that also just happens to be the velocity our long range BPCR bullets send most of their time it seem that a bullet designed to remain stable in that range would serve the shooter best. That may not be the sleekest, highest "BC" bullet. I don't believe it is. I believe it starts with a bullet that does not push the envelop of what length is stable for given twist, but rather a bullet length that is well stabilized by the twist rate of a given rifle.

What nose shape is best I'm not 100% sure, but I believe I am at least headed in the right direction with my current .45 caliber paper patch bullet. I wish I had more time to experiment with nose shape. I have no doubt it needs to be a smooth sided paper patch bullet with a flat base.

It has been a fun and rewarding process.
