I just retired two of my rifles within the last year or so. One was built in 1956 and the other in 1957. They were hunted in all kinds of weather conditions. Spent a week in the field year after year and I will admit that I was maybe a little less than diligent about keeping them cleaned and wiped down.
Neither showed any sign of rust when they were relegated to the "keep for sentimental reasons" gun safe. So while stainless barrels may look "cool" to some, they really only solved a problem that the average hunter never experienced - even with "minimal care" a blued barrel will likely outlive you, so unless you plan on out and out abusing your rifle there is no "need" to get a stainless barrel - get one if you like the looks (and they do look sharp on a black stock), but don't pay the premium if your only concern is longevity.
The Weaver Kaspa is what comes on Savage (international) rifles that come scoped from factory. If you buy a scoped Savage in the US it's dressed with a Nikon scope - some weird export restriction doesn't let them export their rifles with a Japanese companies scopes (????).
The Kaspa isn't on packaged rifles because it's a "great scope", it's there because they buy them at a super volume discount and for the guy who hunts deer with his buddies for one week of the year, where beer drinking takes precedence over sitting a watch. If that's your style of hunting, then the Kaspa is "enough" scope.
Nikon makes a decent hunting scope if you are looking in the 200-300 dollar range stuff (and as of now, Nikon has adopted a "no fault" warranty - even if you run it over with your vehicle they will fix/replace it. I considered one but when I compared it side by side with a variety of models it lost out to a Burris.
If you are keeping your shots to 300 yards or less you have no need of one of the BDC reticles. Some don't like them because you get a "cluttered" view and there are countless designs (hash marks, circles, cascading dots that also cover windage etc) - again, that is personal choice. I would say that many of us (myself included) that have BDC reticles "don't" actually need them - but I think they look cool
You need to get into a place like Cabela's or a decently stocked local gun store where YOU can look through as many scopes that fall into your price range as possible. You may not like the reticle on one that 99 guys out of 100 say is the best scope on the market at that price. You can't shoot what someone else likes if you hate it no matter how good the reviews.
