Please remember that for many years Savage made only long actions, I have a 110fp in .308, that I bought new in 1994 that is a long action. I have 2 long actions that were 223 originally, one still is, the other is now a 300wtf.
However ejection is a weak point in these rifles. at this point I think I have tried all the usual remedies, so I am looking for more ideas.
