What is the IBO speed of a 70#@30" OG?And what range of speed should the BC be at?

IBO is on the web page, don't know off hand. According to the BC, my 29.5" and 60# OG shot at 305 fps with a 300 gr arrow and weight measured at 60.4#'s. With that kind of performance out of a 7+" brace height bow, pulling 60, I am very happy.

I'd be happy too,i was just wondering because i read somewhere that they changed the speeds for some reason.

My Old Glory at 29" pulling 70.8lbs with a 350 grain arrow was shot at 308fps.

IBO is 307-315. Mine at 60#, 29" has a BC speed of 304. I haven't chrono'd it yet.

Hey PA what weight arrow do you shoot and what speed do you get?

Funny You should ask Neuman1, I just went and shot my bow through a crono tonight and with a 368 grain arrow (this is with 27 1/4" arrow with arrowwrap and 3-4" feathers) I got 294fps (I enven accidentally slapped my arm on this shot too) and with a 374 grain arrow, same arrow setup except Bohning Blazer vanes I got 292fps. By the way I am pulling 70.8 lbs at 29" draw. And all I've added to the string besides the factory hush kit is a kisser, string loop and fletcher peep site. These are just about the exact speeds I expected to get when I did the factoring of speed on paper.

I hope you had a 100gr head screwed into those 268 and 274gr arrows.

Yes Sir I did!!!!!!! 100 grain head on both of them. Man she shoots like a champ. I dare the person who whould try to take my Old Glory away from me!!!!!!!!!!!! Mind you this is a big step up for me since I was shooting a 6 year old high country split one with the hatchet cam on it at 260fps.

DUH!!!!!!!!!!![8D] I just realized I put 268 instead of 368 and 274 instead of 374. I corrected it above. Sorry guys.
