Nothing I am saying is new to anyone who has used all of these.
The XTR3 Pro absolutely has better glass than MOST (There are some Kahles with very good glass, they are just rare) 624 and 525 Kahles. This is not really debatable. You can read the reviews from users here or listen to guys like Koshkin who tell you what i am telling you.
Kahles should be priced around $1500, not $3K plus based on their performance alone. Kahles is the premier sponsor of the PRS and the SKMR reticle is named after Shannon Kay.......Ya know the dude who owns PRS. They even lowered the MRSP of the 624 so it could make production class last year. All this being said, almost no one shoots this shit. The only people I see at matches with them, are sponsored Kahles guys. Anyone using their own money is shooting something else, be it a Tangent, Razor, ZCO or Mk5 since this is leupold country and about a half a dozen of the best shooters in the nation live here and are team leupy guys.
Kahles is a part of Swaro but they might as well be different brands. I have never seen ANY swaro product with as bad glass as most of the Kahles I have looked through.
Burris XTR3/Pro is a sub 2k scope that looks like a 2K scope.
Kahles is an over 3K scope that looks like a sub 2K scope
If you really want to piss some people off. A new Gen 3 razor costs less than a new 624 and will blow it away optically.
There is no place for the Kahles optics in todays world IMO. They don't do anything someone doesn't do Cheaper & Better.
