Original Remington Mountain Rifles, Original Rem Classics, Rem 7, "Winchester", Ruger 77, Especially Hawkeye, "JM".
The most collectable are those the least manufactured or desired when they were made.
A lot of truth to the last part of that statement - look at some of the older rifles - anything in .30-06 is typically the least desired nowadays while the odd chamberings command premiums. Things like Ruger’s new Super Redhawk in .22 Hornet will likely be sought after in 20-30 years - unless there is a market I’m not seeing? Made some good “investments” with odd balls over the years.
