I have a Triax maxed out out 70lb. with a 28 draw. A easton storm arrow. 9.3 gr cut to 28.25 inches, and a 100 gr field point.365.05 grains. The guy at the shop figured the speed i should get out on a app.I did forget to add the 3 grains or so for the loop. It said 294. I got 292, 291, 292. It said, with a victory 350 8.7 at 28.25 347.95 grains should be 307, inserts wasn't dry. The arrows was just cut. So I didn't test the victory. I like opinions on this.. I finally got the victor 350 chrono. 304 304 and 306. This Mathews Triax is smoking fast. I must of got a fast one,but from what I''ve read on search and youtube reviews.,They all are fast.
