I didn't sight it in with the bipod, I used a rest. I actually think this is more common than people think. That is why I have said before sighting in for 100 yards at 50 yards is foolish without checking how the gun impacts at that yardarge. Your adjustments are just not as fine at 50 yards as they will be at a longer range. That is a perfect example of why not to do that. I have seen it before. Just because a gun shoots well at 50 yards does not mean it will shoot well or impact correctly at twice the distance. You need to shoot it and see. Once I sighted in at 100 it was indeed about 2 inches high at 50. However sighting in at 50 alone did not give me an accurate enough adjustment to compensate for the longer range. I believe scope parallax plays a role in this sometimes as well if you don't have a scope that is parallax adjustable. Rarely is a fixed parallax scope parallax free at both 50 and 100 yards.

I tried the same thing with my .17 and my muzzle loader. I sighted dead on at 50 yards and then moved the target back to beyond 100 yards. I had to do some fine tuning to the scope to get the windage and elevation perfect. When I moved back to 50 again it was still dead on. (actually the ranges were different because of the ballistics and sight in distance, but the point is still the same.) Niether was this far off, however they grouped much better and didn't have nearly the drop. I think if the lightfields would have grouped better out of my gun things would not have been that bad. I think if you did this with a rifle that shot better with the lightfields your results would be better. It is the same way with archery. You can set your windage at 20 yards, but when you move to farther distances you need to tweak the sights or rest to fine tune it. When you move back up to 20 it will still be the same. I always fine tune my sight at the farthest distance I can group well.

I don't think this gun recoils any harder than my muzzle loader or most centerfires I have shot, so I don't see why it should be shot any different. And I was taught that pulling the butt into your shoulder was improper shooting form and actually increases felt recoil because you are not relaxed while you are shooting. I have found it to be true for myself. I know a lot of shooters that would dissagree with you about holding the forearm down and pulling the gun tight into your shoulder. You should not try to control the muzzle. You should let it do what it wants when it fires. The bullet is gone before the muzzle flips. Proper form and follow thru is just as important with rifles and handguns as it is with archery in my opinion. If that system works well for you though that's great, however I shoot much better the way I was trained to shoot. Not that I don't apreciate the advice, we will just have to agree to dissagree on shooting styles.

And I haven't shot a rifle yet that impacted different with a bipod vrs a rest. I won't be using the bipod on this gun for deer though. I just put it on there because I thought it looked neat. I shoot from a blind with a large window sill I use as a rest. I've been thinking about getting the same rifle in .243 or something and wanted to see what it would look like with it on there. I did shoot a few times at 100 yards with the bipod though and it impacted in the same spot, as does my inline with the same bipod. I have never had a problem with impact points shifting from one type of rest to another as long as the shot was executed properly.
