Some of the new crossbows can be easily decocked. I know Ten Point has a method and I think Ravin does too. The crossbow I have (Ten Point Turbo XLT II) is still like new because I treat it well, and an expensive new one is something I just can’t justify to myself, as much as I’d like one.
I keep a round field target about the size of a volleyball in my Jeep all season, and I have a dedicated bolt with a field point on it that I use for decocking, so I don’t put wear and tear on my hunting bolts.
I just shoot a crappy bolt into my target. I have a run-of-the-mill Barnett.
