Re: How much (scope) power for 600 yd shooting?
14x-15x is plenty magnification for your needs.
I use 3.5x15 Nightforces on my heavy rifles and have shot them out to nearly a mile. I have a 4.5x14x40 Leupold on my 7mm Rem Mag and have had no problem out to 800yds+ (furthest I've shot it).
If some is good and more is better, then too much is just right.
My mind is a raging torrent, flooded with rivulets of thought, cascading into a waterfall of creative alternatives
