I was a gunner till a friend turned me on a few years back to a bow built back in the early eighties it probably has about 20% letoff, 50lb. peak weight, nonetheless started practicing with it in May of that year, i practiced and i practiced to the point where my elbow and shoulders were so darn sore, and then i went out on several 3d shoots up untill the season started in late August. I gained alot of experience in that short amount of time to where i dropped my first deer (velvet forked horn) that first season with a bow.
