Scope dope — I hope! Part 2

Part 1

This report is for blog reader David Enoch and for several other readers who asked for it after he did. When I did the first report on the main cause of scope problems, which is the scope being adjusted either too high or too far to the right, David asked me to explain how to correct the situation.

There are several ways to correct this situation, and today I’ll explain the easiest one, which is also the one most often attempted by shooters: Shimming.

Important fact!
The problem we’re trying to correct here is that the scope does not adjust high enough to get the pellet to hit the aim point. Here’s a very important point about that. Many times, the scope will have been adjusted beyond its upper limit, and the pellet will still be striking low. So, if the shooter shims the scope like I’m about to show you, he may discover that the problem has not been fixed. That’s because the scope was adjusted way too high in the adjustment range. Even though he’s corrected the angle a little, he hasn’t corrected it far enough.

Scope dope — I hope! Part 1

I recently said that, with all the new readers of this blog coming from the firearms world, I need to concentrate on the fundamentals. Today will be such a report.

I was at the range on Tuesday and watched a familiar problem play out. Only this time it happened to a firearm owner rather than an airgunner, and I believe that is why it was such a problem. Airgunners are conditioned early that their scopes don’t look where the barrel of the gun points. Not so for firearms shooters. They seem to take it for granted that the barrel is in alignment with the axis of the scope — which is almost never is.
