So question is if I buy a 300 or 260 and add 50-75 Gt up front would that have the same spine as say a 340 with no weight? I shoot a carbon element and cst at 29 inches and 70lbs
I shoot a 300 axis with 50 gr insert and 125 gr head @28.5" shaft Out of a #69 spyder turbo and it's on the "stiff" side. About 500gr total.
I would recommend doing a test with the 340 shafts with a 125,150, and 175 gr field points to see how they fly. You may go with a 340 with the 50gr insert and be fine (such is adding about 30 grains since you replace the 20gr Al insert with a 50 brass for net gain 30 gr up front). My thought is if you went with a 300 axis you should maybe cut it long, like 28" and go with the 75gr insert to get the spine right. I really like the axis
This year I shot a 250 spine with 180 grains on the front end. 28” of carbon shaft out of a 30” draw bow. With broadheads they tuned up great.
