An update. I checked the poundage on an electronic scale: 46.5lbs[&o]. Was able to muscle1/2 turn on each of the limb bolts. I'm now to 49lbs. If those limbs can go any further, which I doubt, it'll have to be done by someone stronger then me. My ATA and brace height is right on the nose (33.25 and 7.25"), so I don't think I'm dealing with string creep. 49lbs is close 'nuff in my book for 50lb limbs.
