Tasco world class 3-9x40. Dad bought one for my sisters .308 and we were both very impressed with the optics. In my eyes slightly better than the 3-9x40 varix2 leupold we each had on our 300 win mags at the time. So we bought four more. Dad still has one on a 7mm-08, and i have one on a 10/22. In less than two years three out of the five scopes were trashed due to recoil. A .308, 7 rem mag, and a 30.06 did them in. This was about four years ago, and the two others are fine to this day. I think dad is gonna switch to leupold on the 7-08, and ill just keep shooting the .22 until it breaks. Who knows maybe it will last forever. I dont have any confidence in them, id never risk one on a big game rifle again. Im sticking with leupold now, durability and confidence in your gear ranks pretty high on my list.
