Rem. 600?
If the price is right you need to buy it. I bought a 600 in the mid 70's.
It was in 6mm Rem. For a short barreled rifle it was extremely accurate
out to about 300yds. It is the only rifle that I have ever owned for which I have "seller's(trader's) remorse". The trigger problem can be solved with an aftermarket if necessary.
GOOD LUCK and GOOD SHOOTING!!!
