Whats happening to my arrows at 40 yds?

[Virginiashadow]

Feather, yes I am using a drop away arrow rest with field points. I will try to the nock rotation you suggested and see if there is a difference. I only plan on shooting to 40 yards, when in reality I would probably only take a shot up to 35 yards in the woods.

My draw weight is around 65, I got a new 2004 Reflex Excursion Split limb bow. My draw length is 30 inches and I am using 400 grain Buck Hunter Vapor arrows. I tried the 340 grain C2's but was losing some control over them around 30 yards. They shot well at 20, but seemed to be a little loose after that so I switched to the 400's. I use 100 grain field points and 4 inch plastic fletchings. I am not an expert so when a fletching gets chewed up, I re-fletch it with no helical twist.

Thank you for your suggestions, I will try them out this weekend and let you know.
