Thanks Roy, it's labeled as 50# @ 28, but I haven't put it on the scales yet. If the other one is anything to go by, it will be a few #'s lighter than spec.
Er, sorry that should ready HIGH spine (as in 500 vs 340 for my other 50's), even with a part shelf cut in. Did some more playing today and a xx75 in 500 with 100gr insert, 125 point and 50gr brass footing is very close to perfect tuning which comes in just on 630gr and 19% FOC (if that's your thing).
