Re: Optic for inside 300 yds
Those Remington 600's are a classic.
I couldn't find one, so I went for a Model <span style="font-style: italic">Seven</span> in the rare .300 RSAUM. Great lightweight and short barrel for mountain hunting where most shots are under 300 yards.
One of my favorite hunting scopes is the Leupold VX III, 2.5-8 x36mm with Duplex reticle. I have 4 of them on my bolt guns (.223, .243, .308, .300 RSUAM Mountain Rifle, and also 2 in the Mark 4 illuminated on AR-10's.
They are light, short, compact, good light transmission and color clarity and priced right at $399 most everywhere.
The Mark 4's are much more expensive than the VX-III's though.
I just ordered the new VX-6 2-12x42 FireDot and can't wait to try it. Good reviews so far. It's going on my Remington 700 Ti Mountain Rifle also in .300 RSAUM.
