Arrow Speed
All of my bows are tested for arrow speed before they go up for sale. I am serious about bow performance and guarantee my bows to shoot over a certain speed. I use a shooting machine to test my bows. I have found that it is the most accurate and consistent way of obtaining arrow speeds. The accuracy helps me to compare one bow to the next when testing and developing new bow models...
When testing my bows I shoot with an arrow that is 10 grains per pound of bow weight. That means if the draw weight of a bow is 50 lbs. at 28" I shoot a 500 gr. arrow drawn to 28" to test that bow for speed. 10gpp is a very common standard for a lot of bowyers to test their bows. Although some bowyers like to use 9gpp arrow weight...
Arrow speed is measured is 'FPS' which means feet per second...
After much research and seeing what speeds that most bows are shooting at. I have come up with an average or standard for what I consider a fast or slow bow. These speeds are with a 10gpp arrow weight... For bows shot with a 9gpp arrow increase the speeds by 6 to 9 fps on average...
@ 10gpp
Below 160 fps - Slow self bows and primitive bows
160 to 175 fps - Average your average off-the-shelf fiberglass bows and some self bows
175 to 180 fps - Quick some off-the-shelf fiberglass bows and bowyers
180 to 185 fps - Fast mostly made by bowyers
185 to 190 fps - Very Fast not very common
190 to 195 fps - Smoking rare
195 to 200 fps - Holy Grail very, very rare
Here is a picture of the shooting machine. Simple but accurate and effective...
Here is a Link to 'TradLab' where an Independent test was done on my 'Nitro' limbs hitting a speed of 188 fps @ 10 gpp of arrow weight... Putting this bow first in it's class and 4th overall of all the bows that were currently tested... 3 / 28 /2020
