I only use a crossbow because I do not have the time to shoot my compound like I want to.
When I was shooting my PSE, I was shooting anywhere from 10-30 arrows a night, 4-5 days a week, from June until the season. I can't do that anymore.
What I can do however, is shoot a dozen or so bolts every Saturday/Sunday for July and August, and I can be comfortable and Happy.
I owe it to the deer to be accurate and true with my shot. I don't trust myself with my compound after not shooting for a period of time.
