"A really long shot would be 200 yards." In that circumstance, especially if an average shot distance is something like 50 to 100 yards..... then 4x maximum is ALL you ever need. Anything above that is an absolute waste of time - and it will, it most cases, be detrimental to accurate shooting. Most people go with far too much magnification (the ubiquitous 3 - 9 x whatever is mostly useless, if shooting at 200 yards or less....unless set for 3x or 4x.) You could use a 3 - 9x..... and simply use the higher settings as a "built in spotting scope", like many people do. 5x or above is only really useful if shooting beyond 300 - 350 yards....and 9x is completely ridiculous at less than 600 or more. I've seen legions of people trying to use 6x or even 9x at 150 yards.....and silently laughed my self silly, while watching them try to stabilize a rifle to get a clean shot. They never do....and invariably crank the adjustment down to 4x, or something like that. I've also seen lots of people miss shots on good animals, while playing with the magn. adjustment on their gee-whiz 6 - 24 x 50 super-duper "sniper" scopes. Where people get this concept that one must be able to count the hairs on the side of the animal....in order to shoot it accurately....I'll never know. Probably some stupid cr%p from the movies, I suppose.
Anyway, a 2.5 -7 x 32 would be a good all 'round compromise. A 1.5 - 4 x would be better. Of course, everyone has his/ her preferences. I would strongly advise throwing out the old idea that "more magnification is somehow better", though (it is a load of nonsense). I've found that, as a rule of thumb, one needs an apparent sight picture of no closer that 50 yards, for the best (and most comfortable) shooting. This would indicate approx. 4 x at 200 yards.....3 x at 150, etc. etc. I used to shoot a 2x on a .308 rifle, myself....and was as accurate from 0 to 250 yards as with ANY other setup I've ever used. Now, as I am older (and so are my eyes)....I use a fixed 4x. My maximum hunting distances are like yours - avg. shots at 100 yards, roughly - and a long shot would be 200 - 250.
