Problems with the Leupolds? Many years with the same VX 3 scopes on the same guns (.300 Win Mag, 45-70 Browning and .308) I have never had a problem. My guess is any scope you put on you will have problems with. Are your scopes and mounts professionally mounted? (yes or no, no "ive been doing this for years").
Are you shooting quality ammo, staying with the same brand, Wt. and bulllet? Are you shooting from a proper rest? Are you treating your scopes like a precision piece of optics? Are you carrying your gun in a quality hard gun case? If the answer is yes to all of the above, you are bragging about your current scopes, not cursing them. But you will be cursing the next scopes also if you arent paying attention to the other details first.
