With my old nova it is 290 IBO. I am shooting a 384 grain carbon arrow(BEMAN ICS 400) 70 pounds draw and 29inch draw length. I have on the string ultra nok Xl(i know that takes off about 10 fps) Peepsite(NO TUBeing) and catwhisker sileners? thanks


Trap

IBO 290
-10 1" draw length under 30
-10 for the ultra nock
-4 for the peep sight
-7 for 14 grains over 350

Speed = 259 FPS roughly

More of a problem than that, though, is you should be shooting 340's, not 400's.

that easton shaft selector said it should be 400 cuz i shoot a 27.5 inch arrow with my whisker biscuit. and i put 2 inch overdraw in it!

Knowing the bow and the way you have it st up I'd say 240fps---if you're lucky.

Ah, yes, I didn't realize you were shooting a short arrow...my apologies

You know I missed that second part. Don't know what shaft selector you were using, but a .400 is definitely underspined for your specs. .340 would be better.

According to the chart, he's ok, he is shooting a short arrow.

it's cool! my biscuit i can shoot 27.5 and im ok with 400 with that. lol Thanks
