recommendation from the Ashby foundation is 1000 to 1250gr
That’s because the average person doesn’t shoot a 95lb bow at 30”+ DL.
1000-1250gr is recommended because that is what will get the average shooter and bow to the KE or momentum needed for sufficient penetration.
To get a 550 grain arrow to 125+ KE it has to be blazing fast, a dang laser beam!
560 grain arrow would need to travel at 320fps to generate 125# kenetic energy.
I have seen two different posts about it.
1= 90lb bow 590gr
2= 95lb bow 550gr. 125ke
a 550gr at 125ke is 320fps as you stated. A 345ibo bow at 30" with 95lb limbs can do 320fps.
He was shooting a pse evl. Not sure how he got 95lb limbs for that bow, but depending on what mod he was using he could have got 125ft-lb of energy.
KE is what gave him this ability. If you had enough KE, a bow that could handle a 350gr arrow, and a 350gr arrow that could handle that amount of KE, it too could do the job. we just don't have the ability to get there. We are very limited in what we can do. Now, crossbows do.
