Re: IOR 12-52x56 Terminator
I bought mine to shoot out to 2000 yds more or less.
The "wow" is the optic's clarity and contrast, it is excellent. I own IOR, Premier, Hensoldt and Nightforce currently, and have shot a friends Schmidt a good bit. This scope hangs with any of them optically. As to extra magnification, I generally shot long range previously to about 1000 yds and 15-20X was more than sufficient. But in building a .375, and looking to double that range, the extra magnification certainly can't hurt, especially in clearly seeing your target. If you want to dial back you have that option.
Bottom line, it is a well thought out and executed scope. It will get a lot more work in a couple of months.
