I shoot a Buck Master 2000.I have a 29" draw and it's set a 52lb pull.I shoot Gold Tip carbon arrows with a 4 blade 100 gr.Muzzy broadheads.
I've been archery hunting for only 5 years but have taken 2 deer.Both were double lung pass throughs.My farthest shot was about 25 yards and the arrow broke a rib going in and one coming out.He walked about 10 yards and fell over dead.
Arrow placement is far more important than speed,imo.
