I received a response from Talley manufacturing as well. My question was WHY they recommend against loctite, if it was a scope functional issue or if it was something else.
Talley: "we do this because generally people do not use the product as directed. If a little works, a lot must be better. I do not have a problem with proper usage"
Me: TY. Am I correct in understanding that the amount of loctite makes a difference? If so, what is the problem that using too much causes?
Talley: "Gums up the mounts and makes a mess. I cannot do exchanges once loctite is applied"
Once again, the reason cited for recommending agsint it--even after prodding--is not functional, it's more to do with customer service. Which is a big deal if your company spends a lot of time and energy saving customers from themselves, but its not the same as being an actual problem functionally.
I am still concluding that using loctite is safer than not using loctite (if you're someone the rings never come loose on you're no worse off, but if you happen to become someone for whom rings decide to loosen, you're still covered), and if the only reason any of these companies have to recommend agsint it is because it gums up screws, I'm 150% totally OK with cleaning my screws and buying a new set of screws once in a while if needed.
