Wyvern has helped me in the past. Here's my personal $.02 on selecting bolts, boraheads, etc. for use with a cross bow. I am coming from a bow hunting background of 50+ years. Cross bow hunting is relatively new to me. I carried over my philosophy on bow gear to the cross bow ... keep it low risk of issues and stay on the simple side.

I can see no real advantage in a hunting situation for going "light weight" when it comes to bolts or broad heads. Going too light stresses the limbs and can lead to damage ... even catastrophic failure.

Following a manufacturer's recommendation is a good way to go. To me if you are going to deviate from that spec, deviate to a heavier, stiffer bolt and a heavier broadhead.

These "modern" cross bolts launch a bolt at such high speed that the down range loss of a few percentages of velocity due to going "heavier" is of little consequence. I don't try shots past 50 yards anyway. So "flat shooting" is not an issue for me. I ahve target shot out to 100 yards. With a good rest and practice it was not much of a challenge to drop bolt after bolt into a "pie plate" size circle (except figuring windage in a cross wind !!) But I'd never try such a shot on medium game in the field ... though I did try a shot of about 70 yards on a coyote.

I use the bolt weight that Parker recommended for the cross bow model that I have. I use a 125 gr. , fixed blade broad head. I have had absolutely zero issues with the combination in any aspect ..... bolt flight, repetitive point of impact out to 60 yards, depth of penetration, blood trails, clean kills (which is the ultimate test) or managing the arc of 40-50 yard shots.

Guess I have been asleep ... I did not know that Horton folded.

I edited this .... I did find out that Horton was bought by Ten Point. The Ten Point founder was once a big time Parker guy. From what I gather the Parker brand cross bows will be back 2014 .... with the intent of great improvements in quality and engineering.
