I shoot a Bowtech Guardian, set up with 30.5 inch draw, 57 lb draw, and Carbon Express Mayhem Hunters in a 250 spine. Does anyone have a ball park estimate as to the speed of this bow? I shoot 100 grain tips and I believe my arrows are 29 inches. Thank you

The mayham 250 is a 400 spine arrow at 8.8 gn per in. Depending on what flecthing you have your close to 400 gn arrow. So putting 10 gn for peep and d-loop on string and using ibo of 320 that would put you around 279 at best. From what I remember about the guardian your probably closer to 273 range.
I used the archery pal app to calculate this
