I have shot 55#s with 2216 Easton Shafts-29" & a 125 gr head-lots of weight.
I currently shoot 60#s with the same 2216 arrow & very satisfied with results.
I nearly ALWAYS have complete pass throughs on all my animals-Elk, Caribou, Black Bears, Buffalo to name some of the larger ones.
I shot "the chart" size Carbons for 2 years out of my 70# Bow & did not get pass throughs on anything. 5 or 6 Deer all within 20 yds & good hits, 1 Elk (Heart shot).
I gave them all to my son as he likes them.
