isn´t the K98 the base for most bolt action hunting rifles today?
The design, with modifications, yes. The actual gun, no. Most modern hunting rifles don't have claw extractors or static ejectors, not that this isn't a desirable feature on a Mauser, it is, I'm just sayin'. You will find sporting guns with "controlled round feed" advertising the point, though I can take it or leave it. I guess it's a good feature for a dangerous game gun, but I've never had a problem with my Remingtons feeding. Some bolt guns use 3 lugs and 60 degree bolt throws for a little more speed (Browning A bolt). But, they are all on the original Mauser pattern much as most semi auto pistols, while they might not resemble the 1911, use John Brownings locked breech idea in one way or the other.
Sporterizing military bolt guns used to be popular 50 years ago because you could pick up a K98 mail order in VG condition for 25 bucks or less and modify it cheaper than buying an equivalently good sporting arm. Back then, gunsmiths worked pretty cheap, too. Those days are over. You can buy a Remington 700 cheaper than you can buy a K98 and turn the bolt, drill and tap,mod the stock, etc. Savages are excellent sporting rifles, very accurate, and can be had for cheaper than a decent surplus K98 BEFORE the mods. There is no longer an economic reason to sporterize a military gun, not when such quality sporting rifles can be had for such a reasonable price.
And, hell, if I can shoot game with a friggin' handgun, a black powder Hawken rifle, and even practicing up with my re-curve bow, though I haven't shot game with it, why couldn't I use my Mauser or my Hakim in 8x57 if I wanted to? I've used a LOT less caliber/weapon to kill deer and hogs.
