I have a Martin firecat tr1 (single cam) that I bought new in '10 or '11, iirc.
Before I put it in storage in the hard case, it shot great and was zeroed.
I just got it out today and at 15 yards or so I had to use my bottom pin, which was set for 60 or 70 yards I believe to hit near the correct elevation.
I was also hitting to the left a few inches, which could be me but I stacked arrows on top of each other so if it's me I'm consistent. Lol. I noticed that I could see the arrow flying a bit sideways which makes me think that my rest could have been knocked out of alignment. It doesn't look obviously out of whack though.
I double checked to make sure I didn't dial the draw weight down before I put it away.
