I picked up my Vulcan tonight and it rocks. The draw is so smooth and it shoots light out. I actually have it set at 80#'s and it draws like my Trykon at 70#'s. I set it up with a G5 peep, Rip cord, Cobra sidewinder LX and a Hoyt stab. I have a loop, brass nock and the peep on the string. I served up the area where the shock supressor hits the string.
I'm getting some nice speed too. I haven't even played with nocks near the cams. I should get another 6fps or so when i do.
I haven't decided what weight arrow I am gonna shoot yet. I did some playing around though. right now with my Trykon, I am just at 5gpp and getting 290fps with a 370grain arrow. i am happy with that speed. It was quick yet didn't make BH flight tough at all.
here are the numbers for the vulcan.
355grain arrow-321fps= 81#'s KE
370grain arrow-316fps= 82#'s KE
463grain arrow-290fps= 84#'s KE
I think I'm either gonna go with a 400 grain or just keep my speed the same as the Trykon and bump up my KE and momentum with the 463grain arrow. we'll see........
