Last thread on this subject, a good point was made for arrows <600gr for bows in the low to mid #50's! Ive made up 2 doz arrows that i plan to use for everything this year, and it goes like this...KK German Mountain Pine arrows that i soaked in Watco for 6 days, then a few hand rubbed coats of spar urethane, fletch, and a 160gr tip! They came out to 675-685gr with about 13.somethin' FOC! Should be a bonafide killer outta my #55 Bear Montana longbow! Love threads like this as its goin to be my first elk hunt this year!
