First off, that Sedgely Springfield is a nice rifle! That is a style of rifle I really like.
I too favor optical sights just because I can no longer see irons well and they can add about twenty minutes to each end of the day. I am also a fan of low power scopes and in fact, I really like the old Weaver K2.5's. However, I have come to appreciate higher powered scopes for the opportunity they afford for that "last second" check before you shoot. For most species, we are no longer able to simply hunt meat and it makes sense to be able to double check for point count before firing. A couple of years back I had hunted pretty hard all day and finally managed to see the elk in heavy timber before they saw. By the time I picked the bull out though, he had seen me as well. So there I was, frozen in place, watching that bull through my K3 and trying to verify six points. I had forgotten my binooculars and it's not certain I would have had the opportunity to look through them in any case. Standing still, I wasn't a serious threat but if I'd moved, they might have spooked. I stood like that for twenty minutes and that bull never turned his head enough for me to be able to count. If I had been using a higherpowered variable, I might have been able to see well enough to verify what I was morally certain was a six point bull. Instead, I stood there until it was too dark to count points without a spotlight and passed on my elk for that year.
Still, I like the looks and rugged reliability of a low powered, compact, ruggedly mounted scope. I still have that K3 on that rifle but I carry an 8X monocular in my jacket pocket and hope I get the chance to use it.
For real closeup shots, sights of any kind are superfluous and a large front bead is all that is required out to 50 yards and even beyond that providing the stock fits and you practice with it a bit. I am able to shoot 3 to 4 inch groups, offhand, at 50 yds with my 35 Whelen using only a front bead. Good enough to take most game, in a pinch. Practice is the most important part of the equation. GD
