TNW Aero carbine, 16" barrel, 10mm caliber.
I bought one of these 10mm carbines and like the way it handles and functions. I have a question about ballistics from the 16" barrel. I have a red dot mounted on the receiver and had it shooting to zero at 25 yards. I took it over to the 50 yard range and was surprised to see that it was shooting about 12 inches high and about 6 inches right. If I held my dot 12 inches below the center of the target and 6 inches to the left, they dropped right into the center rings. My initial thoughts were that if I am zeroed at 25 yards, I would be a little low at 50 yards but instead i'm way high?? Would I be better off zeroing the carbine at 50 yards and compensating at the 25 yard targets? I'm using 180 grain bullets. Thanks for any advice or information!
