Sounds like a real long-range thing

Which I could not afford to feed.  But still interesting.
It’s usually loaded with a hand-crafted low-drag 1,690 grain solid copper bullet, which it fires at roughly 3,350 fps. The projectile itself is roughly 4 inches long, with driving bands and an aggressive rebated boat tail to reduce base drag.

The sectional density is around 0.70, which is an astoundingly high measure of the mass-to-diameter ratio. It’s very heavy for it’s caliber, nearly a quarter pound.

The ballistic coefficient is about 1.85, which is an astoundingly high measure of how aerodynamic the bullet is during flight.
