Im going on a Buffalo hunt this fall and not sure if what Im packing is enough bow. Im shooting a 50lb Martin recurve drawn to 28in. THe current arrow setup is 29in. Goldtip carbon 8 grains per inch weight tube, and a 250 grain 2 blade zwicky (125 gr. steel adapter). this gives me 696 grain arrow weight on my digital grain scale. I have no experince shooting buffs so not sure if this will get the job done or if i need more bow. THanks for any opinions
