I don't believe I would have bagged my bull without it...
After a last minute need to change my hunting rifle, I ordered a custom turret for my Swarovski 5-25BT on my .270 just a few days before leaving on a Colorado elk hunt. Kenton amazed me by putting the turret in my hands within 36 hours based on the load information that I sent them. I did not have time to test it before leaving. On the second to last day of the season, I saw a 6x6 on a distant mountainside, and after watching it for a while, I realized that he wasn't coming any closer. I ranged him at 650 yards, adjusted my custom turret and fired. The bull took a few steps, so I fired again. He took a few more steps and fell. It took a long while to hike across to his location, but when I got there, I found 2 holes exactly where I aimed within 6" of each other. Based on this experience, I would highly recommend Kenton turrets. I don't believe I would have bagged my bull without it.
