Bareshaft tuning

DoubleLung · August 27, 2016, 07:42:00 PM

I just recently received a Stalker Wolverine which is an absolute stunning bow. It's 49#@28 and I draw about 29". I had some new gold tip classics in a 500 spine I was hoping to use so I tried them full length with 197 grains up front (includes steel insert), expecting them to be weak. I was actually getting a false positive strong sign so I cut them down an inch at a time playing with the tip weights between 50gr up to 200 gr. Literally every combination was hitting the target with the nock left and flew terrible. I pulled out my other 50lb bow and it flew like a dart. At this point I'm frustrated as i feel as though I'm chasing my tail. I then remembered I had some 400's that were in storage as they were to stiff for anything I have had and I ran and grabbed one and cut the feathers off it. It flew much better and real close to what I'd like with 160 gr. up front but I'm going to have to pull out the 100 grain insert to test some more combos. I never thought I'd use that heavy of a spined arrow with a 50lb bow.

Question is, does this seem reasonable to you all and/or is there something I'm missing?

Spine will depend on the center cut of the riser as well as poundage of the limbs. Don't know what that one is, but if it's 3/16ths or more past center, it makes sense.

That's right. Centershot has a significant influence on spine. One thing for sure... if bare shafts fly straight and impact with arrows, you're good. No matter what we think, bare shafting won't lie. :^)

Sorry double post again. Don't know how I keep doing that.

X3 I shoot mostly 3/16" past center, and most of my bows like a 400 spine.

My #45 gamemaster prefers a 400 spine with 175gr up front.

Dynamic spine requirement is far more about the string than it is about any other factor...that is why the Stu Miller calculator is currently rather dated...I have one bow that is a 500 spine bow with its B50 string and a 340 spine bow with its BCY-X string

DDave,

That is very interesting. I'm really surprised to see that much variance. IIRC, you do have a very long draw though--right?

Bows like what they like. My 50 pound bob lee shoots a 390 spine ACC with 200 up front. They bare shaft very well.

These are my feelings as well. A naked shaft can't lie.

I am new to bareshafting and just used it once last week. It worked very well for me and I got my arrows flying beautifully. The one thing I did have trouble with, though, was setting the nock point on my string. It didn't matter where I set the nock, the bareshafts were always low at 20 yards. I finally gave up and set it with my fletched arrows. I am shooting really heavy points(300 grns). Could this be the reason?

Yes it happens with mine and if you watch,it will get mentioned a lot here.I just set it where it always was and forget it.The broadheads fly well.
