I started shooting traditional about 3 years ago and have harvested 5 whitetail with it. It is a 1972 Bear Super Grizzly. Regardless of what I do, or what spine arrows, I have to aim waaaay right. I shoot point-on and I'm about at my wit's end with it. At 20 yards, I'm having to aim about 8' right of where I want impact. Is it me, or should I start over with a more modern bow? I'm shooting off the shelf with a tab release.
