I was paper tuning a few bows and got them all making bullet holes except for one. It's cut 3/16" past center 55#@29 with a 29.5" arrow. When I shoot a 74# tapered cedar with a 145gr point at 25 yards it seems to fly really well but the paper at six feet and also back a bit more shows way too stiff. I started experimenting with weaker and weaker spine arrows even one meant for a light target bow and every combination tears the paper as if it's too stiff. Any ideas?
My guess would be an arrow like that that arrow should be weak out of a bow that is cut 3/16 past, and the rest weaker. What direction is the tear and are you a rightie or leftie?
Are you drawing 29"
Do you shoot 3-under? The reason I ask is I have helped a few guys with paper tuning and I have seen 3 different guys have this same problem. No matter what I did to the bow or the arrow, it still showed the same thing. The only thing that all three had in common was that they shot 3-under. One of the guys tried split and, wallah, he was shooting bullet holes. he did switch to split and tunes fine now. I'm not saying you need to switch the way you shoot, I'm just telling you what I have seen.
Good luck with it.

Different grip causing riser torque
:dunno:
I personally don't pay any attention to paper tuning. I do all of my tuning with bare shafts. Try shooting some bare shafts in with a group of 2-3 fletched arrows and see how they group in relation to each other.
I draw 29" I'm left handed and the tear is to the left of the hole. I don't think it's my grip or my three under form because I was shooting three other bows and got all of them shooting bullet holes. I do have some stiffer arrows I can try.
Based on those answers you definitely need to try some stiffer shafting. If you are using a ff type string you need another 15-20# spine. That amount of spine as pretty much unavailable in cedar today. Get a test pack from Surewood; they are a sponsor here.
I have a 55@29 Blacktail Elite TD cut 3/16" past center. It will shoot bullet holes with a 74 lb spine cedar cut to 30" BOP with a 125 gr point.
what kind of bow? string? and by chances do you have a low braceheight? Some bows are just picky in general! Others shoot a wide-wider range of arrows well.
I was amazed I tried a 2216 arrow and started getting perfect holes at six feet. I tried it at the bale from 25 yds and they seem to fly great.
The bow is a great plains swift fast flight string and the brace is up near the recommended max.
if it works it works.....a 2216 is a 84/86 pound spine shaft fwiw.
out of curiosity is it a skinny ff?
I can't remember the details but it's not a skinny string.
For some reason, my style of shooting requires that I shoot a wood shaft that is ALWAYS way overspined.
Also shooting wood shafts through paper can show a "problem" that is actually just a wood shaft still in the process of straightening out.
Personally, I think shooting through paper is the best method of tuning...it shows what the arrow is actually doing...and if it flies straight through paper it will group with broadheads. It has to.
