[150+ or nothin]

i was wondering how much arrows slow down over distance when they are shot. I know it would matter for different styles of vanes and arrows etc. I was wondering if anybody really knew how much arrows slowed down in fps on shots from anywhere from 35-100 yards. I shoot 440 grain axis (thin diameter) arrows with 2 inch blazer vanes, how would these arrows and fletchings compare to the drag of that of a normal (large diameter arrow with 4 inch vanes)??? just was wondering if anybody thought about this and had any helpful info?

There's a place on that bowjackson.com where you can figure out exactly what you want.

I was thinkin about the same thing earlier. Anyone ever shot their bow through a chrono at say 30 yards?

I just tested this very thing last week. I shoot XX78 2512 with (6) 2" blazers on a strong helical so I'm getting quite a bit of drag. My arrows weigh in at nearly 500gr. I loose 5fps every 10 yards out to 40yds. I'm not willing to shoot at my chrono any further than that.

Look for arrow KE and ballistics on left of page.

Then go to ballistic table calculator, enter info and go.

Good thinking! I am not sure I would trust 40 yds with my recent shooting!

hope this comes out.these are the specs on my arrow and speed of my bow.this simulates you stand at the edge of a cliff shooting the bow straight forward.

Hoyt Trykon at 65 lbs of Draw Weight and 30" of DL
Assuming 80% letoff percentage

Easton Axis 340 shafts
2" Bohning Blazer Vanes
10 grain arrow wrap
125 grain field points or Broadheads

Total Arrow Weight = 439.3 grains

Estimated Launch Velocity = 291 fps
Estimated velocity at 40 yd impact = 283 fps




Hoyt Trykon at 65 lbs of Draw Weight and 30" of DL
Assuming 80% letoff percentage

Easton Axis 340 shafts
4" Duravanes
10 grain arrow wrap
125 grain field points or Broadheads

Total Arrow Weight = 439.3 grains

Estimated Launch Velocity = 289 fps
Estimated velocity at 40 yd impact = 281 fps




The primary difference between 4" Duravanes
and 2" Blazer vanes will be the difference in weight
and the effect that will have on the "dynamic stiffness" of the arrow
and the very noticeable effect on how tight your groups are.
