      I am currently shooting an arrow that is 400 grain total, using a 145 grain broadhead, out of  a 53.5# longbow. The FOC calculation is 17.7%. I chrono’d this setup at 192fps. I have always gotten pass-thru’s on elk and mulies.

      My question is, does almost 18% FOC represent a good ratio, and is there anything to gain by going to a heavier arrow, and if so, should I try to maintain 18% FOC?

      Thanks,  Steve (aka Stix)

      Question;

      If you’re getting pass thrus on elk, what’s your goal ????  Pass thrus on Mastodons ?????

      You have great arrow speed for a longbow & I assume good arrow flight.  My advice; Shoot the heck out of it & then shoot it some more.

      Hi stix

      Sounds like your set up is working great, and no real reason to change your tackle.

      Most people who ( myself included) Dabble in the efoc realm ( my arrows are around 700gr+- tuffheads)trying to get a little extra penetration insurance if the arrow is slightly off mark and hits heavier bone than ribs ( shoulder blade / spine). Personal preference.
