RE: Arrow weight + velocity = penetration SURVEY!
Darn near identical to Turkman's setup....
1. Easton XX75 2315 30.5" long
2.568 grains
3. estimated around 235 fps
4. 125 grain Magnus Stingers & 125 grain Slick Tricks (either/or)
5. Will be a total pass through (the stingers almost pass through my practice target! [&:])
