I wasn't sure why the used (no way to be sure where he had the cross-hairs zeroed) Excalibur Vortex I got was hitting 3-4" high at 20 yards and dead on at 30 yards. I also wasn't overly excited with the groups that I was getting. While admittedly I'm not a great shot, I expected even at 30 yards for my groups to be tighter than the 2 1/2" (guesstimate) that it was. Something wasn't right, and I needed to know why (type A personality, but type B tendencies and time structure...)
I did some research on the good 'ole interwebs and I think I discovered my problem.
When I bought the bow I took it to my local bow shop (not going to mention names, I still believe that they're a stand-up bunch of guys) and the "Crossbow Expert" there said that the bolts the guy sold me (again, used bow) with the x-bow looked like they were all wrong. They each had the remnants of a bar-code sticker on them, which led us both to believe that they were probably bought at wal-mart, and made me wonder how true they would fly with that, albeit little, weight throwing the rotation of the bolt off. He also said that the flat nocks on the bolts weren't what was sold with the Excalibur. He said that Excalibur recommended half-moon nocks, so given this information I bought a half-dozen carbon express bolts that had both types of nocks with them.
After my research on the interwebs with groups that were high but "not bad" using the half moon nocks, I experimented with flat nocks on the new bolts. I had limited time to experiment (after playing in the bubbles my little girl's bath time was coming soon, and I had to help with that) and found that at 20 yards the half moon nocks were still hitting high, but I was getting groups that were 1 1/2" from the outside of the shafts, two were touching and the third wasn't far off. Then I tried the flat nocks and the POI was dead on, but of the three bolts I tried I had one flier.
I've got to do more test firing, but could someone tell me if flat nocks are what these excaliburs come with?
