I think having the standard 98 large ring and medium Yugo versions would cover most cases. Small ring Mausers haven't been made for a long time, usually don't take a scope base well and are unlikely to come up as new sporterizing project. And magnum systems are too precious and rare to not custom stock.
I used to love being able to hit hard at 1000 yards. As I get older I find hitting a mini ram at 200 yards with the 22 oddly more satisfying.
