Re: school me on xbows
Hard to beat Excaliburs new Matrix series for reliability and ease of use. No cam timing issues, easy maintenance, and lighter up front. The 380 is screaming fast. The 355 or 330 are darn nice bows that are easier to cock.
Not sure how your dads shoulders and hands are but the Matrix series get their speeds from very high draw weights. They can be tough to cock for some. Excalibur makes a nice crank cocker that may be needed depending on your dads strength. I would also recommend picking up a stringing aid so that you can twist and change strings with ease to keep the right brace height.
The only negative, IMO, is they are loud. That is more of a issue for the hunter than the deer though. These bows are fast which helps to compensate for them being loud.
Compound crossbows are much quieter and get their speeds with much less draw weight making them easier to cock. The downside is increased maintenance and front end heft. I would recommend TenPoint and Wicked Ridge.
Upgrading your arrows and optics is often times done as well and most are sold as packages. The Excalibur optics are poor, IMO. TenPoints are OK but there are better options out there. The same with the arrows.
Forum sponsor Arrowhead will often times swap out factory stuff for better stuff and only charge you the difference in price plus throw in some goodies. He also makes custom arrows for each specific bow. I would heavily recommend buying from a dealer that sells crossbows because they are into crossbows, not because they just are legal.
I support all hunters, regardless of weapon or technique!
