Loosening limb bolts and poundage

My question is, how much does say, 1 full turn of loosening limb bolts affect the poundage of your bow?

I ask because I recently loosened the limb bolts on my gt500 1 1/4 turns to see how it affected the flight of my arrows.

Here are my specs: 2010 elite gt 500, 28" draw, was told i was shooting 64lbs, but this was before i loosened the limb bolts... i am shooting easton 2216 arrows cut at 28 1/2" with 125 grain heads. total arrow weight is around 517 grains... mechanical release and i plan on using this setup to hunt whitetails.

how much did loosening the bolts 1 1/4 turns affect my poundage? are the 2216s still a good match? when i was shooting with my bow maxed all the way down, thought i could notice a little whip in arrow flight, hence why i loosened the limb bolts. my bow is super sweet to draw now and it seems to me like my arrows are flying better, still don't know if they are perfect, but im shooting pretty decent with this setup. just looking for ultimate efficiency.

any input appreciated.

thanks

Elites are VERY sensitive to turning limb bolts. NEVER, NEVER, NEVER back them off more than two turns from bottomed out!!!!

What is the max weight of your limbs? If they are 70lbs, you can, with two turns, get down to 60lbs and just a touch below.

Old thread, I know, but I have something to add based on information I just learned this summer. On memorial day my brother got out his old 1985 laminated wood compound bow that was set to 75 pounds and per the manufacturer could be adjusted down 15-20 pounds lower than that-- down to about 55 pounds.

Well, on Memorial Day 2022 we had a teenager and a couple of adult women that wanted to try using this bow in the backyard, so he loosen the bolts on each of the limbs where they were attached to the riser and he backed them off to the point where I thought the limbs were just become detached! He took the pressure down to the point that the cables and string went slack when the bow was at rest-- there was "zero tension" on them and they were flopping around (and potentially could come off of the wheels / cams. )
He then tightened the bolts a little bit and we used that bow at what I estimate to be no more than 30 pounds peak draw weight. Of course bows of this era had a 50% let-off this was something that all of the women and teens could handle.

call me crazy but if you were shooting 64 lbs but you have a 60 lb model.... sure doesnt make sense to me. if you backed it off, from the rated 60 your probably around 57? with out a scale you wont be so sure unless its measured

Right. My Pures max out in the low 60s with 60lb limbs.

It is a bit confusing why the 2216 shoot better at lower poundage. I'll try and run the numbers later and see what AA says.

Well, I'm a bit taken aback..... Given your parameters, 2216s with 125gr points are way to weak at 64lbs and moderately weak at 55lbs.

A little but not much. I think it may be a tuning issue. Can you get to a paper rack?
