Is anyone reloading the 9.3x62 with R17. I have gotten ridiculous velocities from my FN custom with a 24.0" barrel.

Previously I have used AR2208 (Varget in the US) with very reliable results maxing out at about 2460fps with 286gn Woodleighs.

Using R17 with WLR primers has upped the ante to 2600fps with 286gn Woodleigh & 2500fps with 320 Woodleigh RN. I got some initial data off an online blog by a chap called Bob Mitchell....

Groups are less than 1.0" at 100 yards with both projectiles & primers are just slightly flattened!!
