Home Forums Hunting & Shooting Ask The Gunwriters Mule Deer's 9.3x62 data

The loads below are for the .370 SAKO / 9.3x66 - NOT the 9.3x62!

Havn't done a lot of shooting with each load but here are my results with the 250 TTSX so far.
I consider these maximum loads and would reduce them by several grains for use in another rifle.
To be on the safe side I would not exceed 2700 fps with 250 gn or 2500 with 286 gn bullets.

IMR4166 (WLR primers): worked up to 65 gn/ 2720 fps and a 1.5" group. Lower charges gave very poor groups.

Varget (210 primers): worked up to 69 gn /2730 fps and a 1.2" group. WLR primers gave larger groups.

Big Game (215 primers): worked up to 72 gn/ 2696 fps and groups close to 1/2".

2000MR (WLR primers): worked up to 72.5 gn/ 2700 fps and 0.8" groups.

N550 (WLR primers): worked up to 75 gn/ 2700 fps and 0.8" groups.

Re17 (WLR primers): worked up to 74 gn/ 2670 fps and 1.5" groups.

All were loaded to 3.34" overall length and all loads were compressed, with the bullets .24" to .35" below the level of the powder.
I had hoped 4166 or Varget would produce the best groups because I don't like extremely compressed loads but so far Big Game is the winner and less temperature sensitive to boot.
I have not yet tried seating bullets deeper than 3.34" but give it a try with 4166 since it takes up the least space in the case.
