Kirby:

Just to shed some light on the differences (although this isn't about the .257 STW) of the different rounds (7mm, .30 AX and .375 AM). If I have them wrong, please correct me. Two weeks ago I shot 3 of your rifles back-to-back on a low wind day, at a 868 yd gong. Since all 3 calibers impacted within 6" vertically/horizontally (my estimation) with the same hold, and we didn't compensate for any wind with all 3, what was the moa drop of each round if they were sighted in at the same distance?
Check your e-mail. The .257 will be headed out your way as soon as you let me know if you need anything else. Thanks!

    With all zeroed at 100 yards this is the drop we would have had at 900 yards. This is not really a fair comparision as the 7mm AM and 300 AX were loaded pretty mild as these were loaded for my hunt in Oklahoma where it was in the mid 90 degree range so I throttled those two down a bit. 3450 fps is not overly crazy for the 7mm AM and the 160 gr Accubond and the 300 AX will do 3200 fps with the 240 gr SMK with max loads but here are the numbers you asked for.

    7mm AM w/ 160 gr Accubond @ 3350 fps....................16 moa

    300 AX w/ 240 gr SMK @ 3100 fps.............................16.75 moa

    375 AM w/ 350 gr SMK at 3265 fps.............................14.75 moa
