Yes, thanks for posting, lets us know how the new material works out.
Hahaha. All that gack I posted for "just an o-ring". Your comment about the teflon is what got me to searching the different materials ... that and the rather high cost to get more than one of Remington's. Honestly though, unless there is an obvious shortcoming from any of them or a quick failure, it will likely be some time before I see any difference. In some searching online, a lot of guys just go to the plumbing section of their hardware store and find one that fits. And they recommend that to others in their forums, so even plain rubber ones must work for at least a little while. I figure I just purchased more than a lifetime supply of o-rings for this gun. I hunt in Texas and it doesn't get as cold, usually, as it does in your neck of the woods in Pa. My 7600 35 Whelen, by the way, came from Pa. I bought it on Gunbroker. Vintage 1988 according to Remington.
