Never fails: Every time I bring the shotgun, I see elk; every time I bring the rifle, I see grouse.
Every time I've tried a combination gun in the last 40 years it screws me up somehow. LOL
Couple days ago I went grouse hunting but it's deer season so I took the BRNO 22HP/12 gauge. Pouring rain.
I don't shoot 12 gauge for grouse but I wanted to be able to shoot a deer if I saw one, dammit. How do you miss a broadside buck at 75 yards 22 HP that shoots great and a grouse sitting on a limb with a 12 gauge? So, I missed a buck and a grouse. That's pretty much my experience with every combo gun I've ever tried. Misfires, oh and I shot a nice blacktail with #6 shot once. One disaster after another.
I'm thinking about giving up on the multi-purpose gun altogether and shooting grouse with the .284 or 7 mag from now one.
