Clarence, I am amazed at the accuracy of the 4k Pro's ballistic calculator. Yesterday's sighting was done with the 6mm Remington and the 5-20x scope. Today I did the same with a different scope, the 3-14x model mounted on a Bergara bolt action .308. Results were the same. I sighted at 60 yards, then in menu told the scope to re-calibrate for 93 yards. Bingo. Same performance. The inner circle is 1".
In order for the ballistic calculator to work, certain variables have to be entered into the scope first, like bullet weight, ballistic coefficient of the bullet, velocity, scope height above bore and zero range. Once that is entered and saved, it's a simple matter to go into menu and reset the distance. The scope does the rest and positions the crosshair where it should be, so it's a dead on hold at any distance with no guess work as to trajectory of bullet hitting high or low. I love it. Granted i haven’t tried it beyond 100 yards, but for 30 yards up to 100 it’s right there.
Years ago I had the old X-Sight 2 scope mounted on an AR 6x45. I took that outfit on a hog hunt and put the ballistic calculator to use. It worked. The first night the guide had me sit in a ladder stand with a feeder at only 20 yards, set up for a bowhunter. I entered 20 yards and dropped a hog with a head shot. The following night I was in a different stand at 120 yards. I dropped two hogs with head shots with a dead on hold, no hold over or under. The 4k Pro scope is far superior to the X-Sight 2.
I used two rifles that night. The stainless is a Remington Sendero 7mm STW that took one hog during daylight hours, and the AR with the digital scope took the other two after dark.
Again, this isn't necessarily predator hunting, but the discussion is pertaining to the scope that will work great for bait site predator hunting.
