Here are the promised chrono results......

To recap the bow is 51 lbs @ 26 and the arrow I was shooting is 450 grains so I make that 8.8 grains per pound

Sorry for the dodgy screen readout....a mis fired .22 caused that!

I think that's pretty darn speedy!
I will have to make up a 510 grain arrow and see what this bow does at 10 g.p.p.
Anybody good at maths to work it out?
