My Hoyt Alphamax 32
 

Was just wondering what kind of fps you gain for each pound you crank your bow up? im shooting a 395grain arrow.

I'll post you a link when i get back to my house it should help you But I'm not sure. Worth a shot anyhow.

http://www.backcountrybowhunting.com/articles/tools.php I just ran my Xforce I'm getting I put in the IBO which is 342. the arrow he shot was 417 grains, and then he ran it though and it was 275fps, now if you punch in 29 inch draw and and 66.2 then it reads 304 fps.

he ran a 350 grain arrow it ran 292. now the website said 324.4fps...... Its kinda hit or miss I guess I changed the IBO to 310 and got the numbers to balance out to what the real deal is so.

I am shooting the alphamax 32 at 29 and 65 lbs. I don't know the exact weight of my arrow but I am shooting the axis 340 with blazers and 100 gr heads at 273.

same arrows and same weight heads im shooting but at a 28in draw length at 65# pounds and was just wondering cuz i was shooting video archery the other day and it was claiming my arrow was only flying at 223fps :/ but was also told the built in chronograph of the video archery robs ya of about 30fps not sure how true this is.

I might be wrong, but I think I was told one time that the speed that those video archery things provide are measure down range.

Most guys, when talking speed of their setup, are talking right off the riser, not 20 yards down range.

thx thats a good possibility but about 3 or so yards out theres like would running along the floor and walls with reflector tape i was assuming that was the chrono if you can call it that.

1# draw weight usually yields an additional 2 to 2.5fps
