Re: High BC pellet development project: Please recommend .22 PCP rifle for testing
For a starting point, buy and look at 22LR ammunition for their projectile shape and weight. There are some very light (20+gr) to 60gr bullets available in various shapes.
Example: 22LR Stinger ammunition has a 32gr hollow point projectile that is rated at 1645f/s. I have shot them and they are reasonably accurate.
A comment, the STANDARD projectile used by the British and Germans in the late 1800's to develop ballistic tables looks much like the ones you show. The point was a curved surface that was twice the radius of the bore and 3 radii long. That means the curvature on the pointy end would have a radius of .22" and a length of .33 inches for a 22cal. See Hatcher's Notebook 3rd Edition Ch 23 Pages 549 and following. These were used to develop tables for rifle and cannon shells.
Another thought to get the mass forward and to provide a skirt would be to mimic the Minie ball that has a hollow base.
Sounds like a fun project.
Sorry I have no knowledge of PCP's as I shoot springers. RWS54 is about the best I know of for power and accuracy in springers. .177 and .22 are available.
