They may not be the newest technology, but they sure work. I run three of these on a 264, 257 wby, and a 340 wby. I have taken 1 antelope at over 800 with the 257 and 2 elk at over 4 and 500 with the 340. Scoped and sighted in the 264 and haven't shot it since. What is this one set up for as far as calibers?
