The 9.3x57 and 9.3x62 are much easier to shoot than my .300 Mag.

The .375 and .300 are about on par. I do shoot them both reasonably well, though.

Using a MOA drop chart (with my MOA stadia wire scope), I was able to hit the 200, 300, 385 500 meter 15" square steel plates in 4 shots, one each using the .300 Mag. The 1,000 meter steel buffalo (4'x8') needed 2 rounds as I shot 1/2 MOA low with the first shot, low centre hit second shot. This was off the bench, of course, and using Winchester 180gr. "bonded" factory ammo.

I used this program - seemed about spot on. I used Remington 180gr. CL for BC (from RP site).

This program also worked for my .243 to 500 meters making 1st round hits easy.
