[QUOTE="J E Custom, post: 1836755, member: 2736"] You will have to check everything that could be the problem one thing at a time and I would start with the scope alignment. If you normally have good luck bore siting, trust it. Then try siting in at 50 to 75 meters adjusting the scope to center it. (The bullet should be at the top of it's trajectory and start dropping at `00 meters so It would be a little low at 100 meters) Any number of things could be causing this so you will just have to adjust around it. The recommendation about the site base holes being drilled off center or canted is not that uncommon. It could also be that the reticle is canted and with the difference in the scope center and the bore center, It could be the problem. If you get a good zero at 100 meters and go to 2 or 3 hundred meters if this is the problem the error will get worst as you adjust the scope reticle If it shoots good groups, there is nothing wrong with the barrel, just the scope alignment. After mounting the scope, try to find true center of the windage adjustment by going all the way left (Don't turn it tight against the stops) and then counting the clicks, go all the way right. Once you have the number of clicks, go back left half the number of clicks and you will have the optical center of the scope and it should be pointing near the bore site picture. If not, there is something wrong with the mounting alignment and it has to be compensated for with scope adjustments. Some times if you take a scope off another rifle it will probably be off because of the other rifle and the new rifle differences. Don't give up, you will figure it out. J E CUSTOM [/QUOTE]
