Roy I have only shot this rifle to 1000 yards on two different occasions. Well actually my wife was at the wheel one time.
Here are some numbers.
MV according to exbal is 2773 with a 107 SMK and a BC of .527 This is over a moderate load of RL15.
Velocity at 1000 is 1466 so she is still super sonic but the energy is down to 510.
My zero is at 140 yards ( i did this because I shoot ittle gophers and I like the point blank tradgectory with this zero)
Come up is 29.25 for 1000 yds here at the house at 4000 ft.
Wind at 1000. With a 5 mph full value you need 3 moa and with a 10 mph full value 7 moa.
I have taken a yote facing me at 653 yards and the bullet exited under his tail with a 1 1/2" exit. I was impressed with this and plan to take a speed goat out to 700 with it this fall.
I installed a JP brake with the thought I wanted to see gopher hits at closer range. It works and makes shooting varmints a hoot. My wife is just starting to shoot. I dialed her in and turned her loose on the 1000 yard target one calm evening. She fired 3 shots at the 2 1/2 " orange dot. One was a hit the other two were about 3 3/4" off.
Note: I had posted the load wrong...!! it is with RL-15 not 19 I changed it now.
