help needed with arrow and broadhead regs please

[Kc_Kracker]

Thanks guys!!

so...
the arrows are 30"
the draw length is 28"
the broadheads are 125 grain

and the draw weight is dead on 60 lbs after checking just now i was told 70 but its 60.
Rainier said these are 8.6gr per ", so...

so if im correct im at 258.3 + 125 for the broadheads putting me at 383.1 ? PLUS another 30 gr or so for fletching etc, so im legal?

[Kc_Kracker]

soooooooo if all this is correct and good, is a spline of 200 on a 60 lb & 325 FPS a good one for elk to? i was told i oughta be in the 300-400 range

Spine is the stiffness of the arrow.I would think you would shoot 340's or 400 but if the arrows group really well it dont matter. besides spine arrow length can change how an arrow flexes as it flies. This tends to be more important for stick bow shooters than compound guys. I know of re curve guys that buy a dozen arrows take 3 and start cutting them down 1/2" at a time to see what length groups best for their draw, poundage, arrow combo.

at 40 yards im pretty solid with groups in a 4" circumference. thats with 200 spline.

It looks like you should be shooting a 340 splined arrow for best results.

When you have 30 minutes to spare, check out this website...

I found it very helpful and informative when I was getting set up. There's other good information on the site if you feel like studying up some more, this link just takes you to the arrow section.

If that is with a broad head and that is your max yardage then id say your OK. You may be able to tighten it up some more with more refinement.

I can't take it anymore- the word is "spine," not "spline."

I can't believe I did that. I even know that...
I could blame it on autocorrect I guess.

KC, one more question about your draw weight are you getting that 60lbs at full draw or part ways through the draw?  You might have a 70lb draw and when it gets to full draw and the letoff you may be at 60lbs.  You would actually have a 70lb draw bow and would need to match your arrows to that.

[Kc_Kracker]

its set at 60

A 70 pound draw weight with an 80% let off would mean he'd only be holding 14 pounds at full draw, not 60 pounds.
