I like my Prostaffs. Have them on a .223 Rem (my varmint rifle) and a .260 Rem (my deer rifle).
Make a little paper insert with the yardages for your pet load or ammo inside the lens cover (like Butler Creek) that fits inside the cap and is treated with waterproofing.
The other end of my deer scope I put a Tenebraex filter to prevent glare or shine. Because I try to get close and THEN shoot.
