Found used at a pawn shop. Looks unfired. Checked limbs with cotton balls for cracks/splintering. Rail has no marks or wear. Varizone scope is dead on at 20 yards. Got it for a song.  Anything I should know / any advice ?

I have an excal micro 335, they are skmple and effective, u don't need 400 fps to hunt deer, I shot a buck at 55 yd last fall, arrow passed thru, the buck ran 10 yards and died.  3rd deer in 3 seasons.

There is a youtube channel "death by bungee" that covers just about everything.  I stuck with the OEM bolts and broadheads, but I did add luminocks.  Know your zeros, use a laser rangefinder.

And have fun, they are great bows.
