Wyr is on the money about the Mausers.
Mauser prices, at least here where I'm at, are a lot like Mosins in prices.
You can find some as cheap as $50 all the way to $150-200 depending on the country of origin (rarity, etc.) and the overall condition.
Unless you go with milsurp ammo 6.5 X 55 and 8MM ammo can get a little pricey (as compared to, say, 7.62 X 39, .223, 7.62 X 54R, etc.).
But, like Mosins, they are a blast to shoot and about as addictive.
The K98 (or sometimes called just 98) is considered the work horse of the Mausers.
The 48 and 48A (little brothers of the K98) are a fine, fine weapon with the 48A 'generally' being in better condition than the 48.....difference in the 48 and 48A being the A has a stamped magazine floor plate and trigger guard......which is no real biggey.
The Swedes are becoming increasingly harder to find so if you run across one in good shape at a good price (I paid $219.....pristene) I suggest you grab it.
I don't know the specifics why the Swede has problems on slightly beefed up ammo since Swedish steel was considered, back then, to be some of th world's finest steel.
I don't know if it's chamber and barrel thickness, a difference in bolt design or what.
The Mausers, as with many older mil type bolt actions shoot high at 100-150 yards but an over sized front sight blank can be had from Brownells and then filed down to zero which I've done with great success.
If you didn't catch an earlier thread the Swede round is near that of a .270 with the ballistics of a 30.06.
