PPU 303 elevation table

[Parashooter]

Using figures at Prvi Partizan Ammunition we can calculate the BC using available ballistic software ("PCB" in this instance).

Range 1 (m) : 0 Velocity 1 (m/s) : 750
Range 2 (m) : 300 Velocity 2 (m/s) : 589

Calculated BC : 0.492
(Not too surprisingly, the published median BC for the Sierra 174 MK is 0.493. Close enough?)

Anyhow, input the BC and MV (2460 fps) into your favorite software routine and you can get all the trajectory data you want. If you don't already have a favorite, try http://www.jbmballistics.com/cgi-bin...j_simp-5.1.cgi

Useful information Parashooter, I just got some PRVI .310 174 FMJBTs to try in my .310 groove diameter Krag. I was wondering about the BC.

To add to this, I discovered by accident that if you zero the rifle with the original service method, PPU 174gr factory ammo shoots close enough (on military Figure series targets, anyway) to the Mk VII sight graduations for range work. I'm halfway through practical data gathering/verification for the table and I hope to have a complete and tested one back to 600yds this summer.
