Re: SFP or the FFP for big game rifle hunting
You bring up a good point and it's something each individual needs to take a look at. I call it target clutter. At long distance and high magnification how much info does one want to sort through?
My experience is while walking or close range stalking low to mid magnification is set. Ranging is seldom used on quick target acquisition on fleeting game.
High magnification at longer distances would be used after one has glassed and determined distance to target and has compensated for atmospheric conditions.
The op made a point to mention that his scope would be used for hunting up to 600 yards. I agree with the Leupold w/bdc, or any other high quality scope with custom turrents would be adequate.
I'm of the opinion one should buy a high quality scope once as in the future rifles can be switched out under good glass. Too many times we see owners switching up glass (check the f/s forums of this site, snipershide or optics talk and one can find all sorts of recent mid to mid-high glass being swaped out or being offed.
Remember, with continued development of warfare and high-end sporting glass there is a steady stream of last years latest-greatest available. Much of this glass is little used, high quality and can be purchased for a fair price if one is patient.
