Re: Shot The New 9,3X62 Today

luv2safari,

Congrats on your new 9.3x62! It has become one of my favorite cartridges. It sounds like you're off to a very good start with it. Here's some of my load data that you may find useful. Both loads shoot to the same point of impact at 100 yards with my rifle. The Prvi bullets make for less expensive practice ammo. (As usual, the standard caution applies about reducing the powder charge and working up in your rifle.)

Date: April 2, 2005
Cartridge: 9.3x62
Firearm: CZ 550 American
Scope: Leupold VX-II 1-4x
Barrel Length: 23.6" (60 cm)
Bullet: Prvi Partizan
Bullet Weight: 285 gr (18.5g)
Powder: RL-15
Powder Weight: 59.0 grs
Case Make: Graf
Primer: WLR (not magnum)
C.O.L.: 3.29"

Chronograph
Shot# Velocity fps

5 ___ 2,422
6 ___ 2,423
7 ___ 2,399
8 ___ 2,401
9 ___ 2,417

(Only 9 shots in this test string instead of 10 as I forgot to turn the chronograph on for the first shot!!)

Summary
Average Velocity: 2,407 fps
Average Energy: 3,667 ft lbs
High Velocity: 2,423 fps

(Coefficient of Variation = std deviation / average velocity -- Just a handy ratio for comparing one load to another.)

This is the load I used in South Africa during August 2005. See the thread Back from RSA - photos for some of the results.
