When I had a $150 scope on my muzzle-loader I missed several deer. Turned out my mounts went to crap and were letting the scope move around. Then when I got that fixed the scope went to crap and I missed 2 more deer. That is when I took the scope off and haven't missed since. I also have missed a longer shot chance on a deer a few years back when I accidentally breathed on my scope and fogged it up.
Simmons or Tasco?
Weaver, Leupold, Burris, Nikon, all good scopes along with others too numerous to mention.
I bought a 50 dollar chinese scope just on a lark at a "tool sale" in Victoria once. It has lighted reticule and didn't have that on a scope. It's been on my CVA wolf through several hundred rounds, now, since doing duties on an SKS. It's got good optics and hasn't broke. I'm pretty amazed at that. Could break any time, I guess. I'll put something else on it better if it does.
I've taken one deer with it so far.
To each his own. I've taken deer with irons. Did it just this year, but scopes are better, I'll admit that readily, and I don't mind spending money on a good optic. Bare in mind, too, I'm retired on a semi fixed income at the moment. But, the scope is more important than the rifle IMHO on a good rig. No need to get crazy, though. I knew an old German fellow, gone now, that would own NOTHING, but Schmidt and Bender. Well, I ain't that well off.
Would be nice, though, they were pretty awesome.
To each his own, though. I have two places to hunt, now. One is deep, dark woods and the other could allow for a 150 yard shot, though all, but one deer taken there over the years that I can think of were 100 yards or less. Scopes help in either situation. Of course, as I've said, when I hunted west Texas and the mountains of New Mexico, scopes were more a necessity than an option. I made a 370 yard cross canyon shot on a mulie once with my 7 mag which didn't even come with iron sights or holes to mount any. A Weatherby Supreme 3x9x44 sits atop that one. GREAT scope and the best optics of any of my scopes.
