I have to say that for it would be a hard choice between a Finnish MN, Yugo M48,Mauser 98, VZ24, No4 (MkI or II),Swiss 1911/K31 or a Springfield.
As I have all but the M48 its kinda hard sometimes to decide what I want to shoot more.
From my experience, if you can find a Finnish 91/30 theyre worth the extra coin as the Finn's worked over and turned them into a rifle that'll shoot, as well as an M39, those are straight AWESOME rifles and worth the prices on them. I have a couple Russian 91/30's that I use for blasting mil-surp ammo, but thats what theyre for right?
The Yugo M48 and the other Mauser variants are good rifles too. My favorite of all of them is the VZ24. The ones I've owned have been head and shoulders above all other 98 variants I've gotten experience with. And 8mm is still relatively cheap.
The Lee-Enfield No.4 is a great rifle, either straight or as a restoration since there are alot of them that've been butchered, I mean sporterized
, and its about the only turn bolt rifle you can get trigger happy with lol.
I've lucked into a Swiss 1911 recently 7.5X55 is a great round and coupled with the rifle, either a K31 or 1911 variant you cant go wrong.
And my favorite is a 1903 variant, you just cant go wrong with one. Theyre out there too, just dont jump on the first one you see, as with every other rifle everyone else mentioned, shop around ALOT andget what you want, not what the status quo recommends.
