I could use the 3X9 scope that is on my 30-06, it's just that I might be faster to aim at close range through iron sights, all I have to do is put the rear sight back on and adjust it and it's good to go. 1X, that must be a very wide sight picture!
Last November Firearms deer season I set up in a pasture where some wheat had been planted, I sat in a bulldozer that had been left there for over a year. I had a doe only tag, and it's about 5:45 AM, still partly dark, and two deer walk by about 50 yards away. I had my 7 Mag, had three Core-Lokt 150's in the gun, and since my scope filters light, I could see cleanly through it, so I shot the bigger of the two. I could have just as well used a 30-30 right there in that open pasture. To this day, I still have that box of 150 grain Remington Core-Lokt, with a single round missing. Next year I'm invading the cedars. I'll get a nice little lever-action 30-30 to use for that.
