Of interesting note from Ashbey is concering extreme FOC arrows. Specifically carbon. Arrow Lethality Study- 2005 2005:
Quote:
"All indications are that extreme FOC arrows do, indeed, offer a substantial gain in arrow penetration...... what little data at this time is suggestive that only the flexional characteristics of carbon shafts allow one to achieve an extreme FOC while maintaining good arrow flight" And later ... that it may offer highly significant gains in penetration when boradhead/arrow integrity are maintained."
This sort of testing by Ashby gains a great deal of respect from me and is of something that should be noted and of worth to people who like to use lighter arrows.
I'm not sure of your meaning here. Ashby was still using heavy arrows. Light shafts, extremely heavy points. OL Adcock also shot trajectory and world distance records using the same theory of extreme FOC. It blows away some people theories that a low FOC will produce a flatter shooting arrow as well as some theories that suggest that high FOC arrows will noise dive.
