RE: Classic Bows??
They killed plenty of deer back then. The ones in decent condition are still just as capable of putting meat on the table. The deer haven' t changed. They aren' t wearing body armor. They don' t duck any quicker. They darn sure aren' t any smarter... though some have more ' education' than others.
A nearby WMA requires a minimum 3D score to get into one of their draw hunts and our club puts on a shoot each year to let folks qualify for it. One fella showed up this year with one of the old 6 wheel Bear Whitetail Hunters. He qualified and intends to hunt with it. There were several mid-80' s vintage Hoyts and PSE' s running around the course as well. It ain' t how fast the bow shoots, it' s how well you shoot it.
But if you do decide to go classic and buy an old compound, remember that when they were built the minimum recommended arrow weight was 6 grains per pound. Considering their advanced years, I wouldn' t go less than 7-8 grains per pound on one of the oldies.
If you wanna talk even more classic, the old recurves from the 60' s and 70' s will still do a number on a deer too.
