Exactly the reasoning of my advice. If he can put all of them on paper off sticks at 100 yards I couldn't care less if they crossed and when.
Knowing where they cross is somewhat worthless trivia. It is trivia you discover while getting a load to regulate the sights but it isn't a goal of the process, just something learned by the process.
How big a group, four shots, two from each barrel, are you making at 50 and 100 yards shooting off sticks?
I've got some groups that are well within 2" for 4 shots from both barrels, however they are crossed. I get what your saying, I often argue with myself what does it matter which barrel it came out of if the point of impacts are relatively tight. Would an elephant be any less dead from a bullet that crossed over it's intended point of impact, of course not.
Here are my points, or the factors contributing to my unhappiness with the results I'm getting.
1. I paid a lot of money for this double, just shy of 30K.
2. I paid extra to have this double regulated to 90 meters.
3. Crossing to me just isn't right, and not a sight of a proper build.
4. You never no how far you need to shoot, and naturally with crossing issues it only compounds with distance.
I completely understand we all generally intend to shoot our big game animals at relatively close distances, but sometimes the terrain only allows so much distance to be covered. I certainly would rather have the option to shoot out to 100 or 150 yards if I needed to.
