See I have a TR2 and my arrow is roughly 40 grains less.. pulling 67 lbs, I am surprised I am not getting close to 300 fps..
I wonder what is going on...
MDGrand - I thought the 400 FMJ was spined way too light for the TR2 at 67#/29.5. Also was not sure how you are getting 400 grains from the FMJ. So I just put your info into Archers-Advantage figuring your shooting a 29" arrow at that 29.5" draw.
Still not sure where that 400 grain FMJ is coming from.Anyhow, AA shows the 400 spine arrow is leaving optimum spine at 49# of draw weight. Perhaps your not getting the speed because that arrow is trying to fold in half at 67#! Just a thought.
Following AA, which I have come to trust, the 300 FMJ fits spine better using the info you've provided. Though that really messes up your FOC if your using a 100 grain point. Estimated speed with Blazers and no wrap 287 fps. All carbon Axis 300 should leave you just shy of 300.
Martin bows are usually over rated in their speed listing. But yes I would agree you should be faster than you're showing.
