Re: scope selection : 7mm
Don't settle. I've shot a 7mm Rem Mag for 30+ years. The first 10+ years, I used a $39 Bushnell Banner and it was FAR worse than your Redfield. I took many nice Muley's with that cheap scope, including a 34.5" Buck at 875yds.
I'd say, put the redfield on there and see what the rifle will do. Set a little $$ aside for a few months and get THE scope you want. I currently use a Leupold 4.5x14x40 on the 7mm.
I like the lowest mounts possible, as it helps me maintain consistent form, that's why I don't use the larger objective scopes on my walk/stalk rifles.
Hope this helps,
If some is good and more is better, then too much is just right.
