Thanks for all the great replies everyone!
The Mosins and the K31's are two choices that I can readily agree with. I own one of each and they both consistently end up in the rotation of range trip guns. The K31 in particular has become my precision rifle of choice. Two weeks ago I shot a .324" group with my handloads at 100 yards. I have less than $250.00 invested in that rifle, that covers the rifle, the scope, and the scope mount, it shoots so well I can hardly believe it.
I can also agree VERY strongly agree with the Llama 1911 clones being a good bargain. The second handgun I ever purchased was a gorgeous blued Llama 1911 in 9MM. I bought that pistol 14 years ago and paid $200.00 for it. I still have it today. It is accurate, pretty, reliable, heck I just love it!
As others have already mentioned Marlin Model 60's are another one that is completely underrated. The very FIRST firearm I ever owned was a Model 60. It was a Christmas gift from my parents when I was 15. This Christmas will make 19 years since I unwrapped that Model 60. I still love it just as much today as I did on that Christmas morning. For a lot of years I kept track of how many rounds I put through that rifle. I stopped at 30K, and that was 8 years ago!!!! Two years ago the bolt hold open broke. I bought the replacement parts but haven't put them in yet. I think maybe I'll fix it soon and start shooting it again.
Maybe .22 rifles are the best bang for the buck? Who knows!
Keep 'em coming everyone.
