Okay guys, if you tune your bow should you tune it at the dw you plan to use. Or does it matter?

If your shooting bullet holes then really only thing that i notice is drop in arrow,with field points or broadheads,just a matter of sight adjustment,but that my experience only............

I tune with everything the exact same way I am going to be using the bow. Same weight, DL, let-off, arrows, everything.

Well, lets think about this a sec.. It doesn't change the timing, doesn't change the physical placement of your centershot, or your knock placement. The cables keep your ata the same, so a few cranks of your limb bolts shouldn't matter a whole lot...

but then again, if you drop/raise the dw enough to require a different spine arrow, you may need to make some adjustments to your centershot to compensate...

I think it may be best to set your draw weight first. If it was me, anyways :p

I tune it to the DW I'm going to shoot it, but in most cases that's only 1/2 a turn from max. I have found that after tuning, a full turn or so either way doesn't make any difference to arrow flight but may have to adjust sight pin a little if I'm shooting with sights.

I agree. That's why my 3D rig is my huntin rig and vice versa.

Mmmmm? Well, if the arrow spine is compatible one can lower the draw weight quite a bit, 15 pounds, vary draw length maybe a inch and still have a well tuned bow - just adjust sights and continue shooting. If you note some of my posts I've shot arrows slightly under spined to way too stiff and all found the X. Look at the Carbon Express arrow chart and see the difference of a CXL 150, 250 and 350. Beman 340s is quite stiff for my bow and yet it's X time with them. Just yesterday or day before I show a picture of the left hand helical CXL 350 in the X. And another pic in here somewhere in here shows a CXL 150 in the X.
Basically, a well tuned bow will shoot a variety of arrows and remain quite accurate. Still, one should tune a bow for the arrow or have a arrow compatible with the draw weight.

Saturday afternoon. I set up a new 2008 Pearson Z34 for this man. I set it up just like normal with exception for his over and under caliper release (wide jaws, either side of the arrow thing). For the nocking point I used the top brass nock as the nocking point, 1/16" high, and the brass nock under the arrow was set to give about .040" up and down play. Okay, his caliper jaws clamped on the outside of the brass nocks. Not once did I consider his arrows. Some 400 somethings from Cabela's ($50 a dozen on sale) and there was one odd ball arrow. I did correct the arrows so that all were the same length (one maybe 1" longer than necessary and the rest 3" too long). Last thing to go on was his fixed pin sight. Where to set? Easy. Align the arrow with the string, move the sight so the pins are just on the outside of the string (ball parking it). The up and down I left to shoot in.
We went to the practice range, 10 yards. X with the first shot. Okay, I got lucky, real lucky. Two more stayed in the bull's eye. We backed up to 15 yards, still in the bull's eye. We backed up to 20, still in the bull's eye and one to two were dead Xs. Of 13 or 14 arrows only one went just a tad right, just out of the bull's eye. Made me feel good when the man said that what he just shot was the best group of arrows he ever shot.
Now, he wanted to try a little difference in draw weight. First, I had backed off the draw weight to 62 and then to 55 (which I shouldn't have), then 58 pounds and back up to 61 pounds and him with a 29" draw. There was no difference in accuracy....

Ok with out the incidentals YUP IT DOSE MATTER , so do it right and do it once I always say use the arrow that hits the x , thats the one that matters :)

EH, I would have to agree that is the way I do it. If your going to shoot the bow it is set for your dw, dl, let off and so on. I tune it at my dw.

you can tune a bow, but you can't tuna fish.

(couldn't resist)

so, why would you want to tune it at one weight and then change the weight? just wondering.

I can't speek for anybody but myself although I'm sure there are others besides me who do this. When I am practicing in the off season or shooting target I drop my poundage to around 55 or 60#. Don't need to shoot anymore weight than that. However, when hunting season arrives I crank the poundage back up to 70#. The tuning on the bow does not change. I do use different sights for target and hunting so it's just a matter of a slight adjustment to the pins and I'm good to go.
