I put a fixed 6x scope on my 35 Remington and a 3x9 on my .41 Mag. My theory on magnification is put as much as you can afford or stand on it. 6 or 9 power is pretty good for 100 yards. of course I put a 3x15x56 scope on my 17 HMR so I am all over the map when it comes to power. If I had all the money in the world I would put one of those15x55x52 night force scopes on everything I own. Oh well when I win the lottery those will be the first purchace orders to go out.
