I want to phrase this carefully so please read the entire post.
My first xbow was an Excalibur Axiom with the high end sight. I had it zeroed in 5 or 6 shots andthe sight had great adjustment to 50 yards. It was noisy, had little range, and wide. It was also bullet proof. I dry fired it one time with no downside. I'm not recommending that you dry fire anything, it was a stupid moment.
I so enjoyed the xbow that I decided to go for what might be the best xbow on the market, the Tac 15i.
My Tac 15i was DOA for a bad crank mechanism. That took a week to get the parts in.
I then had numerous problems trying to zero the xbow as described in my HHA postings.
While working that issue, one of my limbs started to seperate. Had to wait another 10 days to get replacements.
Have now sent my scope back for a replacement but have a loaner Parker scope on it while waiting.
I'm almost afraid to say that all is working fine at this time. Nailing tacs to 60 yards, thanks to the advice from xbow755.
All the above has occurred in a one month period. Oops, forgot to tell you that my string stops started splitting after less than 200 shots!
I can't wait for the new arrows on the horizon so I don't have to worry about spines, etc. I will also be installing the timney trigger and the drop away rest when I am sure I don't have another problem.
So, if you think I will now be recommending you get the Excalibur, you are wrong. Just be prepared for the worse case scenerio but also be prepared to get an Xbow that blows everything else away when things are right.
If you get a good one, you'll be elated. If you get one like mine, be prepared to spend time and patience to get it right. PSE has made good on all repairs to date and this site will help you through the rough spots.
If you want to play it safe, get the Excalibur. If you want unsurpassed performance, get the TAC 15
