The bow was not made for me, I am the 2nd owner. I didn't think of nock fit at all, it is probably too tight, I will have to fiddle with that.
As far as the calculator goes-arrow- gt7595, 32", 200gr,15gr insert, 1" footing weighing 13 grs (spec on the 2213 shaft), 15gr on the nock (added 4gr for 1/4" 2213 footing on 11gr nock) and 4" feathers (I assume this is specifying 3x4", however I shoot 4x4")= 66.1
Bow- D/R longbow, rated 55# @28, DL 31.5, shelf location 1/16 (measured the side plate, 1/16"), string B50= 68.4
Now, if I do as skarcher described and add 5# because gt's are stiffer (his post 1st page), if I build out my side plate to 3/16", that should be about right. I may try that.
