A fast recurve 60lb bow could get a 600gr kicking at 190-200fps with a 28" draw. Thats a fast one like a adcock bow, or totally fiberglass recurve.

Your typical longbow or recurve usually shoots a 10gr/lb draw arrow at 28" draw at 175fps. So I see a 50lb bow usually shoot a 500gr arrow 175fps. With a super clean release, maybe 180fps.

With a selfbow solid one piece I usually see 155fps for same criteria of 10gr/lb draw arrow. I have however seen a holmgaarddesigned osage selfbowwith heat treated belly shoot 180fps.But I know I can't build anything that good.

There are claims out there of selfbows that shoot 190-200fps with 10gr/lb of draw. But I have yet to see it. Its kinda like a unicorn.
