Ha, I don't worry about replacing 15 expensive scopess
i'm a born minimalist. Or at least I operated as one for the last forty years. I never bought any where near 15 rifles, so I avoided getting a good scope for all of them.
Look good companies seek improvements. I expect it. The question I ask myself is if the improvement made the old one absolutely obsolete. Leupold made some nice scopes ten and twenty years ago. I'll retest one Leupold in the early spring and decide then if mine needs replacement. Improvement never meant replacement , in my minimalist practice.
