Might be best to ask your instructors, good luck, I hope I get to take that course some day!
AHhh that’s so sweet ...one day I plan on doing it as well
Good for you and learn lots ...have fun
I would guess the 300 would be best for bucking the wind ...since the us army went with the 338 for there sniper rifles ...I remember the video they talk about the entire gun but can’t remember if they were using 285 gn or 300 otm Berger bullets
Cheers have fun
