I bought a Stealth NXT crossbow by Tenpoint. It came with one of their multi-range reticle scopes. The scope has a zoom ring which also correlates to arrow speed and has markings for both. Basically, its a second focal plane scope and you are using the zoom ring to adjust the distances between the aiming points to adjust for the actual speed of your crossbow shooting some bolt/tip combination.
I was not aware that Tenpoint has a page for how to sight in these scopes. You can find it here.
The salesman said it is bore sighted at 20 yards, zero it there. Move back to 50 yards and zero it there. Then bring back to 20 yards and adjust the zoom ring/arrow speed dial to dial in your reticle.
So that's what I did, a few shots and it was zero'd at 20 yards. A few more shots and it was zero'd at 50 yards. Then I think it took 3 shots to adjust the speed/zoom ring to be zero'd again at 20 yards. Then because I'm OCD and have never bowhunted before I decided to test my broadheads. Initial thoughts....at 20 yards the break of the trigger and the impact are pretty much simultaneous, at 50 I could start to catch the arrow flight.
I pull out the broadhead safe target at put it at 40 yards with the assumption that I'd consider that my maximum range. If I was on at 40, everything else should be good to go. I grab an bolt with a lighted nock just to see how much more visible they were and put on a broadhead. NAP Spitfire 100 gr. I shoot once and its 3-4inches low. WTF? Hmm, try again even though I know I didn't pull the shot and low again. Low and I can catch the lighted nock during flight but not as accurate as I wanted. Well hmm I put a field point bolt in and dead on at 40 yards. Ok lets start removing variables. I grab one of the bolts with the lighted nocks and put a field point on it thinking maybe something is different. I almost hit my previous impact point, easily a 1/2" group at 40 yards.
At this point my scope is zero'd with field points with all my bolts and nocks but not with the broadheads. Ok maybe there is something goofy and I can just adjust the speed dial and know what my adjustment is and then know it'll be off but consistently off with field points but accurate with broadheads.
I knew how much I had to adjust the speed dial to cover that approximate distance at 20 yards and figure ok start with half of that. Put a bolt in the dirt almost 3 feet away from the target...$%*# Adjust it back with a new bolt and a new broadhead and the next arrow completely misses the target the other direction hits the ground, ricochets up a tree and is gone....completely and utterly gone....$(%*$*#(#(#(@$(#(!!!!!
I was pissed and knew it was better to call it a night rather than continue to spend money. My friends who own the place I was shooting found the bolt and everything once the sun went down and the lighted nock showed up in the darkness like a beacon.
WTF!!!
