Here's my regular 100lb compound bow i built shooting a 222grain arrow 434fps, with the 150lb version of this bow with an over draw and a 187grain arrow i believe 550fps is possible, without it being a specialized flight bow rig
Here are two vintage browning bows I've recently rebuilt with new cables and strings, both bows are shooting a 530 grain arrow, both set @ 30 inches the blue/silver one is 80lb & the red/black one is 85lb. Both have the same riser, limbs & cams the only difference is the blue/sliver bow has steel cables with a fast flite system, the red/black one has conventional cables and string, the blue/silver bow shot 250/253fps on multiple shots & the red/black bow 259/263fps, I was expecting the 80lb bow to be much slower due to having steel cables
Here's a release aid I've been working on, still needs a bit of work and a tidy up but it's functioning fine.
Here's a clip of me weighing and shooting a 130lb compound bow in one take
Here's a martin krypton I recently modified, currently set at 120lb (140lb max). Not a high performance bow but for strength training it's perfectly fine
this year I set a goal to shoot over 110lb+ left handed, i started at 40lb and within 2 months I was shooting a 95lb hoyt comfortably, I will say this single cam has a lot harder draw cycle compared to the 95lb hoyt, the bigest hurdle so far is the bow arm elbow and forearm needing time to adapt to the load, it really shows 90lb+ isn't that big a deal to reach and I'm not a gifted individual in terms of physical prowess
