Well that stinks. I about did the same thing 5 year ago. I did my typical obsession where I was working to get a new bow tuned. And shot and shot for a few weeks, until my shoulder pulled. Doc said if I kept it up, I would have to move to a crossbow. Since then I try never shoot more than 50 arrows at a time.

Most people I have seen try mag loads that are newcomers gave up pretty quick. I took several months last year week after week trying dozens of combos. It burns the cold winter.
