Dating my remington 1100
But you have to ask for them as most will stock/sell you a natural rubber or butyl o-ring.
There are many elastomeric compounds that are impervious to petroleum based lubricants, including Viton which is what is most widely recommended and sold for 1100s/11-87s. Neoprene is available from industrial suppliers, but who needs 50?
I never had the initiative to learn much about them though! My friend had a large amount of Winchester/Federal, 2 and 3/4 inch shells and that's what I have been using (I'm about to buy some Remington). The Magnum part i'm kind of scratching my head at, I could find these rounds when people talk about them online, but never actually found any in person or online.
This is something that I will NEVER get rid of, it's more important to me because of who's it was, rather than what it is. So I will know for sure, i'll also buy some Remington shells, along with bringing the Winchester/Federal rounds, to see if that makes any difference as well. Always happy to be apart of a good working Forums such as The Firing Line.The other reasons you mention have no basis in fact Do NOT get any lube on the O-ring, they brass pistons are designed to run dry."If it rattles, it's a Remington" is the old saying Thanks for all the input guys!but ok - before we tire this young fella out ...we'll agree to disagree...Magnum versions have 1 gas port versus two, if it is the slightest bit dirty, that explains your ejection issues.
