I have 2 Burris, a 2X and a 3X with a adjustable AO. It has been on my Contender, 357 Max, 223 and 45-70. It's been trouble free, and it's a old scope, had it for 30 years or so. Have 3 Buris II Fullfields, they have been fine too.Shot a nice doe with my 15" Encore 7mm-08 the other evening with the 2x Burris on it. Had weird results, 139 grain Hornady blew a fist size hole on exit on far side, high up in rib cage, but found bullet just under skin near entry wound??? The deer was walking normally when I shot her at 80 yards, but I don't see how the bullet ended up where it did unless it had been shot before?Will know more after I butcher it on out.
Right now, hunting with my Encore 7mm-08 rifle with Bushnell 3200 3x9 with rain guard.
I use Nikon, Bushnell, Weaver, Burris, Buckmaster, Simmons, and Mueller, never had a failure with any of them.
