Gents: I own a Smith & Wesson .460 XVR (bought from Cabosandinh) which will also chamber the .454 Casull. I put a Nikon Force XR BDC 2.5 - 8X scope on it. I have shot it on 4 occasions, using the .454 round, and I keep hitting the target low. Per the tech specs, for every click on the scope adjustment, it's supposed to move the point of impact 1/4 inches at 100 yds. The problem is that when I make adjustments to the scope, I keep hitting the target low. It seems that no matter how many clicks I apply, I keep hitting the target in the same spot: Low. In other words, adjusting the scope is having no impact on where the bullet strikes. As of right now, I have maxed out the upward adjustment on the Nikon, and the bullets are hitting about 8" low at 100 yds. I know someone who had a similar problem with his .44 mag. He took a rubber mallet and applied some 'love kisses' to his scope. After that, he was able to get the scope to respond properly. I haven't applied any 'love kisses' to my scope; I guess if it is 'stuck', I'm surprised that the recoil from the .454 hasn't loosened it up. I contacted Nikon, and I got the standard boiler-plate reply of, 'Send it in for servicing'. I'm reluctant to do this because of the general hassle, plus the fact that I'll have to remount the scope and shoot it in all over again. That ammo isn't cheap! Any suggestions?
