Well, I guess great minds do think alike!!

Date: April 23, 2005
Cartridge: 9.3x62

My CZ 550 cycles fine with the 286 gr Nosler Partition seated to a COL of 3.34 - 3.35 inches. Plenty of room in the magazine and the throat.

Shot# _ Velocity fps

Summary
Average Velocity: 2,356 fps
Average Energy: 3,526 ft lbs
High Velocity: 2,375 fps
Low Velocity: 2,335 fps
Extreme Spread: 40 fps
Standard Deviation: 11 fps
Coefficient of Var.: 0.47%

Notes: Very accurate load. Basically duplicates the Norma standard 9.3x62 load of a 286 gr bullet at 2360 fps muzzle velocity.

I just haven't gotten around to trying the 286 gr Nosler Partition with 57.5 or 58.0 grs of RL-15. I was concentrating on the Woodleigh bullet as that was the bullet I wanted to use in South Africa on my recent trip. But, the Nosler Partition would have been an excellent choice also.
