Stu Miller calcualtor question

[acollins]

I had a Bear Super Kodiak.  It was 50# @ 28".  I was shooting a 2117 out of it and got all my info. for the arrow from Stu's calculator.  I sold the Kodiak and bought a Howatt Hunter 42# @ 28".  When I put my bow information in the  bow inputs section  for the Howatt hunter it has a higher number than the Kodiak.  Why is this.

My second question in what would be a correct shaft to shoot out of the Howatt Hunter.  It is 42# @ 28.  I am shooting it at 28.5  

Thank you.

Did you put in exactly the same arrow information including insert and nock weights?  Most "errors" with that calculator are from the riser cut from center dimension.  I don't know how far either of those bows are cut past center, but that number makes a big difference.

I tried to get 2117s to fly for someone with a 28" draw on a 53 pound Howatt Hunter. They were cut at 29"bop, it took 200 grains up front to get it fly. For a 42 pounder unless there is tons of hardware up front. A 2016 with a heavy point or a 1916 with 125 grains would be more likely

I punched in both bows on the DSC and get 1# lighter dynamic required for the Martin......basically to the same arrow required.  Yes, the draw weight on the Martin is lower but it has a riser cut 1/8" past center where the bear is cut to center.  If you are using the same thickness strike plate then they ought to shoot the same arrow well.  One thing to double check on the Martin is the draw weight.  Nearly all that I have owned were 2~4# higher than marked weight.
