29" dl, #67 draw weight, st axis 340's 9.5 grpi, wb rest, 100 gr field tips, 2" blazers, 28.5" arrows. i'm guessing around 400 gr's total weight with insert. 306 fps.
does 306 FPS fall in line with IBO?

Looks like the IBO would be about 345 fps based on a 400 grain arrow weight.

Elksalya, I saw one yesterday set up about the same and the speed was between 305-312 depending on which arrow was shot.

i also have a d loop and a g5 1/8" peep. i was also told by the dealer that BT recommends that after draw weight is maxxed to back it off 1/4 turn. thats why i'm at #67 draw weight. does anyone know why BT recommends this?

Here is some real world IBO weight numbers.....

27" draw set dead
60 lbs
300 grain arrow
straight out of the box: no tuning
brass nock and rubber thingy.lol
350 destroyer
313 fps repeatedly...
I have to say the draw was awesome. I have never shot a 6" brace height bow that felt so good on the shot and after the shot. Usally I have a problem with the 6" hitting my arm. This bow never came close. Price tag is to high but I guess I'm a tight wad!!!:zip:

According to the spces above that should be around 345fps IBO bow. But when I looked at the Bowtech sight it said 342-350fps. So its pretty close

The D350 I shot with Octane Hostage rest, 65# @ 29", 430 gr. arrow was 294 FPS. That was with Spec. Archery Peep (housing only), D-loop, and string leeches. So, I would imagine that dropping 30 grains and upping the poundage to 67# would get you in the ballpark for 306 or higher even with a WB. This particular bow was lower in the IBO range for the D350 as spec'd by Bowtech (342-350 FPS) with the birth cert. on this particular bow saying chronoed it 343 FPS from the factory.
