When it comes to the 9.3x62, I'll be the first to say, for the most part, I'm not a pioneer. I discovered it here on the CF and the AR. I've simply followed suit and mimicked John's and others examples. When John said he used Varget or Big Game for the 250 Accubond or 286 Partition, I got in step.
Where I did diverge and break away from the pack is having Leupold install the CDS elev turret system on my VX3 1.75-6 and make the 250 Accubond load a combination I can use out to 470-685 yds (near sea level to my 10,500' mountain elevations). I bought three of the turrets; 500', 5500' and 10,500', since the 2nd and 3rd turrets were 1/2 the price of the 1st. For those individuals who claim the 9.3x62's max range should be no further than about 300 yds, better grab your oxygen. The 3rd, 10,500', turret will take me out to 620 yds, not that i'd use it that far.
Something of interest. The 250 AB @ 2600 fps drops about 5" more than a 180 Ballistic Tip/AccuBond in 30 cal @ 2700 fps (30-06!) @ 500 yds.
