I've spent much of the evening reading what I could find on fixed and variable scopes.  My focus is the 6x and below range, primarily because most of my shooting will be off hand and  even when supported, still likely at ranges less than 400 yds.  I read a great deal of debate where seemingly knowledgeable fellows state that the 6x42 is a wonderfully bright and crisp scope (the FX Loopy seems to have a good following, and once in a rare moment, somebody pops in saying the SB smokes it - and of course, then the pizng contests begin).  Often times, the question arises why the 6x42 should be so fine vs for example a 3-12 x gazillion scope, dialed back to 6x.  It is a good question.  I don't know, only speculation and reasoning.  My guess is that there are fewer lenses / fewer air / glass interfaces in the fixed scope thus much lower losses in transmission and fewer distortion effects.   Now that's a guess, does any body actually know ?  While we are here - I'm considering running the SnB 6x42 along with a T1 in an offset LaRue mount.  Am I about to spend a lot of money doing something stupid here?  thanks in advance for your comments, sorry for the monologue.

This topic has been covered recently. A fixed power scope optics appear better and are better $$$$ spent for seeing at the same power due to the reasons you give above. Today these diffrences are not so great due to technological improvements.
Why limit yourself??? A 4-12 or 6-120 would serve you better for those 400yd shots.

Thank you.  I'm sorry - I attempted , repeatedly, to search this topic.  Apparently I don't know the right key words to find the hit.  

A 4-12 or a 6-20 would, characteristically, add substantial weight.  Also, anything more than 6x off / hand is wasted on me.  Rather like the reason most binos are maximum useful at 8x - just too much shake.  Now I realize the SB will weigh a tonne , but I'm prepared to suffer that for what I anticipate will be a forever purchase.  One of the more frequent and apparently respected posters here called the 6x42 "optically perfect".  I thought that was rather challenging statement , rather unattainable, but taken in the spirit it was intended, a great endorsement.

Plus - the T1 offset was made to look around an ACOG.  Big objective bells are just going to generate clearance issues.  On the fence between the FX3 and the SB - 6x42

Saw it.  Quite unimpressive IMO. Very narrow FOV.  Loopie at 17, SB at 21, and this SS scope at 13?   The 8x S&B has a wider FOV.  Don't know who spec'd out their scopes - but ...  I'll pass, without even a second glance.

This one will out glass the Leupold by a bit which will put you closer to the S&B while still being affordable.  http://swfa.com/IOR-6x42-Hunting-30mm-Rifle-Scope-P1843.aspx

Thank you for that suggestion.  I had overlooked it completely.  Excellent suggestion.

I don't foresee the future that well, but I am sure some of them will be.  I believe the well known rule of thumb 1x per 100  yds - applies to a very good marksman.  In my case, I think 1x per 70 yds is a better rule for my skill level.  The conquest is a nice scope, I have the low power variable (although quite large, it is very bright and sharp).  I'm looking for an upgrade though - S&B, but maybe the IOR which looks to be interesting as well.  Thanks.

Sorry - last one , but I should credit the management out of respect.  I ordered the S&B from SWFA.  Thank you for hosting this forum.

I suspect it is a typo.  The field of view of the 6x42 S.S. should be around 20feet at 100 yards.  I will check when I get it next week.

Would be a shame to have lost competitive selections on that basis, good to get corrected.  I've already ordered the s/b.  I believe you once called it "optically perfect" , so I've got extremely high expectations having read your opinions quite extensively (not to impart any responsibility to you for my purchase decisions, just that I usually enjoy your critical process.

S&B 6x42 is a superb scope.  The optical formula is well worked out and has been optimized over the years.
