When you are talking bb's to hunting bolts you are comparing apples to oranges...BB's(couple of grains), very little or almost no ftlbs and no "sharp" point to speak about, hunting bolts 325 to over 500g and usually a very "sharp" point installed(and sometimes over 100ftlbs of energy).....Remember your physics, an object in motion tends to stay in motion unless acted upon by an outside force, there is no such thing as a "spent" arrow or bolt, as long as they are in motion they are capable of massive damage to tissue bearing animals.................As far as giving you a web-sit to look at for speed results I do not know of any. I gave you an example in the other response I wrote(that being the most recent), Archery and hunting related items including long guns and black powder rifles have been my life for over 22 years. In that amount of time I have shot almost everything(except Great Lakes products)thru the chrono and from experience have seen alot of manufactures that do not "exactly" tell the truth. Sorry I can not be any more specific than that(and I did say that Ten-point made a good bow).
