Regarding to arrow speed I found interesting some datas I got.
I just received a heavier set of limbs for a coming BIG exotic game this summer. I play around set up to assess "real " performance out of my bow and shooting.
I found an arrow that fly very well for me and allow me shooting out to 30-35yards with good confidence. Bow is 65# at 31" and as I draw a tad further I am getting 67# on my digital scale.
I tested 2 set up and will end with the " lighter" 800 gr plus a little external footing
GT big game 100 shaft for both
Brass inserts, point and matching broadheads will be from Tuffheads
First set up 200 gr solid glue in brass insert and 225 gr point: very tough combo
Second set up : 50 gr brass insert 100 gr steel adaptator 300 gr point : less strong as 50 gr brass insert is the weak part
