My Browning A-bolt chambered in 7mm Rem Mag has had a Burris Signature 3x9-40 on it for 26yrs and is now serving duty on my fathers old Remington CDL 700 chambered in 7mm Rem Mag. In any case when it was time to replace it, I had completed nearly 2yrs of reading forums and reviews on the Burris Eliminator lll which prompted me to purchase one to install on my Browning 7mm. I have since used this rifle and scope combination for the past 3yrs off the bench at my local range which has target bunkers installed from 100yrds to 600yrds. Off the bench shooting Premium factory ammunition by Federal, Hornady, & Winchester. Shooting this ammunition from my rig has allowed me to hit every target on the range from under 1 1/2" groups on the 100yrd targets out through the range on 8" steel plates hitting each consecutively, even on windy days using the winds advice given in the scope during ranging. In addition to shooting from the bench I have hunted BEAR, COYOTE, MULE & WHITETAIL DEER, MOOSE, & ELK throughout ALBERTA CANADA in the fall with temperatures fluctuating between +10 F to well below -20 F. I have adjusted the ballistic coefficient on this scope for 5 different loads, made 100's of range requests through sleet, snow, & fog yet have not needed to replace the battery. Albeit, ranging targets in adverse conditions is certainly not absolutely fool proof, but it performs well enough to satifiy my expectations from a scope and rangefinder. This scope has served me very, very well & my only criticism is the optics are not as clear as I initially desired & that the remote activation switch introduced on previous models and on the newest Eliminator lll does not retrofit onto my older Eliminator lll.
