All guns can be different. I was shooting my Black Diamond XR today and the first shot was 2" higher then the rest. Now that might not sound like a lot, but when you figure at 50 yards your already 2" high, then add 2 more inches, you better be a little careful where you aim for that first shot.

To make sure I checked it at all the different ranges. Of course once it is dirty and I swab between shots, it behaves perferct. So I think I will just fowl the barrel if I decide to use it tomorrow instead of the Wolverine.
