I normally shoot bows in the mid-50's because of shoulder injuries that ultimately resulted in extensive surgery almost 7 years ago. But when hunting buffalo, a bow in the 70 pound range is about the minimum most of us think is required. This year I again began the months of building to get back to shooting a 70 pound bow for another buffalo hunt in Australia. It took about 3 months to get comfortable again at that weight. As long as my strength is good and fatigue has not set in, I can shoot a 70 pound bow more accurately than my normal weight bows. I shoot best with a hold of several seconds at my anchor point, so I have to be stronger than if I were "snap shooting." The stability of the incredibly strong limbs of my new Shrew Safari, along with the stability of my body being held firmly in place by the higher forces and the clean release of the string being ripped from my fingers all lend themselves to consistent form, arrow flight and shot placement. My heavy arrows fly like darts, especially when they weigh 1000 grains, with 500 of that in the brass insert and broadhead. I would like to have shoulders healthy enough to shoot a 70 pound bow all the time, but that's asking too much from this 60 year old, torn up body. Although I don't seem to be doing too much additional damage to my shoulders when shooting heavier bows, they feel sore after every long shooting session using more than about 60 pounds, so I'm sure the added poundage isn't doing my joints a lot of good. I love my heavier bows and recognize that for hunting some animals there simply is no option other than stepping up to more poundage that can launch heavy arrows at reasonable speeds.
I'm glad I'm not left-handed so I am not tempted to try to shoot Patrick Kelly's much heavier bows when we are together at the range!!!
