In case anyone is curious I did hear back from Martin/Damon Howatt
"All our Damon Howatt bows are built to follow standard amo build spec's using the industry standard 28" AMO draw length unless something else is ordered at a specific weight at a different draw length then what the industry standard is.
As with most every traditional bow made today you will gain typically between 2-4 pounds per inch past the specific 28" amo scaled weight that bow was built for. This is called "stacking".
So in reality. Yes that draw weight is correct weight at your longer draw length.
If you need a 45# draw weight at a 31" draw length you would need to special order one custom built specifically for your 31 inch draw length. So that bow should now draw around a 30 pound draw weight at the 28" amo standard. Or just have yours relabel it at 45# @ 31" to possibly avoid any legal
Now there's another possible serious issue with that now because if you're hunting with a bow that's built and labeled for 30-35#, it may not be legal for use in a lot of states for big game species depending on their minimum draw weight requirements.
As far as it damaging the bow it's hard to know with so many factors involved depending on arrow weight. Outside temperature. Any signs of prior abuse on it, etc, etc.
But a good things for you to keep in mind is that all of our bows are draw length tested out to 32" or 33" and they are then draw cycled on a draw machine for either a 10,000 or 20,000 draw revolutions.
But please read our disclaimer in our traditional bow section for minimum arrow we we suggest to avoid any warranty issues.
