Thread: Bare shaft tuning

So iv been playing with my bow a PSE EXTREME for a few weeks and had it shooting mint groups out to 50 yards with field tips. Today I went and threw some broad heads on to see how they went and couldnt hit a barn door from 10 yards let alone 50. I heard about bare shaft tuning was a good way to but I'm a little confused at how it actually works iv got my group at 10y with my field tips and bare shafts and they both completely point in the opposite direction.

So my question is what do I adjust??

When I adjust my biscuit to try get the the bare shafts on the mark my fletcher arrows fly further off the mark. I cant seem to get them to tighten or at least hit the target the same.

yeah.. well from the title, the subject matter is way different from what I thought it would be.
I'm going now

Your centershot and or arrow spine is way off I suspect.
Have you paper tuned your arrows ?

Iv had no issues with centre shot when using field tips but everything went pear shaped once I started with broad heads and bare shafts. I used the gold tip chart to get my arrow spine my bow is set at 70lbs and my draw is 29.5 which gave me an arrow spine of 300.

So have you paper tuned either fletched or bare ?

I'll watch this thread with interest, haven't the foggiest what you's are talking about. Maybe someone can explain.

Why is this guy shooting unfletched arrows?

Is he actually putting a hunting tip onto unfletched arrows...but that would be like shooting an arrow with the fletching up front.

From the physics of air resistance, I'd expect a broadhead tip requires heavier fletching at the rear of the arrow. For stability, the rear must have more drag than the front of the shaft, and a broadhead will have more drag (from greater surface area) than a blunt tip. I'm not bullshitting, I'm just explaining why I'm confused what's going on.

what broad head are you using?

The idea is that you want to be able to get a bare shaft to fly as straight out of the bow as possible. It's optimal to apply that force as directly in line with the arrow as possible. This is maximizing the efficiency of the arrow allowing it to collect as much energy as possible from the limbs. Once you have achieved that then all the fletching does is correct minor errors in the release, grip and flinches. @Cordite

Am with Ground Control , paper tuning will show you what your arrows doing between the bow and target.

Here is a good article explaining the process and how to adjust:

Also spin test your arrows with BH if you haven't done it yet @silentscope

Spent the morning flinging arrows at paper to see where they are at. I try make adjustments with my biscuit to get this better but nothing changes on the paper. Is this pointing towards arrow spine being wrong?

So after a but more mucking around inswitched to the bare shafts again. Some major adjustments on my biscuit and my d loop I almost have perfect bullet holes. Now I need the rain to stop so I can go try a bit further then 5 yards.

I have been watching a lot videos lately on the subject.
This guy explains it for traditional bows.

I ll look for the other video I saw for compound bows

This guys is very good as well in his explanations
