Toes,
I have never discussed the issue of relative strength of the two mounting systems with anyone from Leupold, but I have in the last couple of years with the top guys from Badger and Swarovski, plus with some military and LE armorers that I really respect. Some of these armorers work with both styles daily, and their knowledge is what I particular value since they handle more equipment than most gunshops could imagine.
Metal to metal contact is made when I torque the sideplates on my Badgers by tightening a 1/2 nut. How can that compare to forcing (twisting) a steel dovetail into a steel cone so that metal to metal friction alone will hold it in place. Even if you only twist the ring in once you have probably scratched metal away - ever notice how much easier they get to install if they have been removed and replaced several times?
Besides bending a set of Redfield style rings during a hunt, and seeing them self-destruct when I remove the rings from the dovetails (as in when switching from a 1" to 30mm set of rings) I would never claim to having as extensive knowledge as many of the factory guys. I am fortunate to talk to individuals from several major scope companies fairly regularly, usually when I have some dumb question that they always answer. I have some good contacts at Leupold and will discuss this with them when I can. From a sales viewpoint, what your letter states is the ideal position. Who is going to state that one of their products is inferior to another in the same product line?
There was a point in time when I figured a scope mount is a scope mount, doesn't really matter who designed or made it or whether it is made of steel or aluminum. I have changed that opinion based on personal use, and from the saticefaction that I get when I know that my mounts are as good as the scope and rifle.
My hunts span a pretty wide range of species and types of activities, from the tailgate that you mentioned to horses, canoes and lots of walking. If the weight of my Badgers ever becomes an issue I will take up golf
Bottom line here is that I believe that there is a significant difference between the inherent strength of Weaver style tactical mounts (Badgers/MK4's) and the Redfield design as made and sold by Burris, Leupold, Millett, etc. Guys like Marty Bordson can go into the engineering technical stuff to explain why this is so, I don't really give a ****, common sense tells me that it is a fact. If this was not reality, why are they universally used by the military and most LE.
Other bottom line is that a bunch of guys have convinced themselves that Dual Dovetails are just as good or better than tacticals, plus they are way cheaper. These guys simply will not spend the money, nor have they ever used tacticals (fact is tacticals are **** expensive because you really should buy a 70$ Seekonk 65 in/lb snap wrench for torqueing the suckers on with, plus either buy a torque screwdriver or get someone who has one to install the little screws on the ring caps). These are also the guys who don't like how "heavy" those mounts are.
I have no doubt that most users of Dual Dovetails will get good service from them. I see 19 dollar aluminum Tascos at the range all the time and those guys are saticefied too. But I have never heard of Dual Dovetails on Marine Corps sniper rifles, must be some reason for that...
Toes, as you can see, I have a pretty strong opinion on this. I bit the bullet and switched my hunting rifles to Nears and Badgers so that I never have to worry about my mounts letting me down again.
I would be very interested to hear S1's comments on the relative strength of the Weaver/tactical design vs the Redfield mounting system.
