Had my CZ 550 FS out yesterday. Normally I use 65 g. of Big Game with Speer 270 g., PRIVI 285 g., and Hornady 286 g. loads and all normally get close to 2400 fps in my 20.5" barrel.

After reading Mule Deer's comments on powders in his new book (he went to 66 g. of Big Game with 286 g. bullets); I decided to go up in powder with the Speer 270 g. Went in 1/2 g. increments to 67 g. With 67 g. of powder the chronograph just barely reached 2500 fps. Load seemed safe in my rifle. Will test it more for accuracy.

My rifle seems to like the Speer 270 g. bullets and Yukoner says they work very well in his considerable experience with the 9.3X62.

"It is wise, though, to remember above all else: rifle, caliber, scope, and even bullets notwithstanding, the most important feature of successful big game hunting is to put that bullet in the correct place, the first time!" John Jobson
