Hi guys, new to archery and bow hunting. I'm shooting a mathews switchback XT, 70lbs, 28" beman ICS 340'swith 100gr tips. Shooting with 3 pins, 25/35/45, holding about 8" groups at 50yds. Even if I get my groups down outside this range should I still shoot a deer that far out? What should I expect in terms of accuracy? Love shooting it though, having a blast. Thanks.
