At what poundage are you getting that speed? I shoot a McPherson Accu-Max @ 73lb (locked down limbs), 357 gr arrow (Easton ACC total weight with 100 gr Thunderhead). I can consistantly get in the mid 290’s. What sucks is I am 6’5″, and they had to custom build me a draw length of 34″. Lots of arrow required to make it to the rest.
Regardless, that is one fast machine. Enjoy.
