Long range bow
7mm
This being a long range hunting site I will try and make a
comparison between rifles and bows.
Back in the 70's archery was going through some major changes
in technology's ( compound bows with cams, arrows made of
all sorts of materals, releases ,etc ) All designed to increase range
and efficiency.
Ethics was a big issue then and there were lots of opinions about
the issue of long shots with a bow.
So being ethical I decided to do some flight test for Accuracy,
Distance,Velocity and energy and hear are "my" results.
With the bow set at 70 lbs (considered average for hunting) max
distance was 345 yards with 500gr arrows and 430 yards with 700
gr arrows.
100yrd groups= 500gr arrows 10" to 12" and 8" to 10" for the 700gr
arrow.
60yrd groups= 5'' to 6" for both arrow weights.
Arrows dont have a lot of energy (60 to 70 ftlbs) but have quite a bit
of momentum so penetration is effected by weight( the heavier the arrow
the better the penetration with the same broadhead and bow weight.
So it appears that bows and rifles have something in common as far as
long range (heavy is better for wind,accuracy and distance.
I feel that a 100yrd shot with a bow is like a 1000yrd shot with a rifle
possible but very difficult.
I feel that 1'' 5 shot group per 10yrds of distance ( 5''@ 50yrds, 6''@ 60yrds)
is max
Heavy arrows 50 or 60yrds max on elk.
Light arrows 30 to 40yrds max on elk
The same goes for deer size game.
I have taken over 150 big game animals with my bow and even
though I shoot 90 to 95lbs of bow weight and 700+ grain arrows I still
limit my self to these distances.
These are my limits and every one must set there own based on ability,
equipment and game to be hunted.
Just my 2 cents
