RE: Arrow weight + velocity = penetration SURVEY!
Last year:
1- Carbon Express CX200 Hunter's, 28" long
2- 386 grains
3- 268 fps
4- NAP Scorpion XP 100's (mechanicals)
5- Complete pass through on 3 deer.
This year:
1 - Carbon Express CX200's, 27" long
2 - 356 grains
3 - 300 fps
4 - I will be using Wasp Sharpshooters or Stingers this year. Cut-on-contact should be better for penetration.
5 - KE is up to 71 ft/lbs so I have no worries about pass throughs this year.
