| I wonder if they taught Marines that bit about the distance between the rings affecting zero. I think your approach makes sense--and it wouldn't surprise me if individual troops did the same! | ||||||

For reference, the above message is a reply to a message where: I find myself thinking about the difficulties a Marine sniper in WWII would have keeping his Unertl scope adjusted in combat, wondering if they had wooden boxes to carry them around in. I really don't know if they stored or transported their rifles in gun boxes but I believe they treated them like a part of their body while they carried them. I have accidently bumped my scope tube hard enough to move it against the horizontal and vertical adjustment springs and the springs recenter it instantly and it seems to go back to exactly where it was. The first time I did it I thought I would have to go back to square one and sight the gun in again like you do when you take a scope off a rifle and put it back on. I was surprised to find it was still zeroed. I'm careful to minimize that kind of contact but, so far, it hasn't ever changed the zero. Another odd thing I've read about these scopes is that the distance between the mounts affects the value of each click of adjustment. If they are 5 inches apart each click equals 1 MOA. If they are 7.5 inches apart each click equals a quarter of an MOA. It's just geometry I guess, but I found it odd. In real life I just make whatever clicks are necessary to zero the scope at a new shooting distance. |
