Re: U.S optics 10 x mil dot too much fo a rem 40x?
It'll work, but definitely far from ideal.
You're not going to be able to really test that 40X with a 10 power scope. The mildot is worthless for this setup, nothing to holdover for at 50 yards.
The proper scope for a 40X in benchrest is a fixed 35/40/45 power Leupold Competition series with a fine target reticle.
It'll cost a heck of a lot less and be infinitely more appropriate.
But hey, if you want to put an ACOG on your 50 BMG Barrett, waste that money.
Works? Yah.
