We have a mauser mod 98 in 308 nato we want to convert.But what calibers can we convert to we don't mind going wildcat or normal calibers all input is good as far as gun goes i have 3 all together this is the only one that is being costumized

Get a brand new 7mmx57 19" replacement barrel from Sarco for $35.00.

You can convert to any caliber from .170" to about .510" and use any case up to the Jeffery- or RUM-size. Anything over .458" will need to be more or less straight walled, meaning rimmed or belted, e.g. 50-110. There are conversions done on the Rigby case, the big Weatherby and the Lazzeroni likely, but there's a bunch of smiths out there who don't recommend a case that large for the 98 Mauser. The cartridge can easily be 3.34" long with minor feed work (which for the Jeffery or RUM would mean trimming), and a good smith can aparrently get you 3.6" if you really want it, though if it were me I'd get a long action to start with for that sort of thing.
So, as far as chamberings, you can have anything you can find on the 308 case, anything on the 30-06 case, anything on the 458 Win Mag case, Dakota's short line (270-375) and the 416 and 458 versions such as the Howell and Vincent Short, resp. There's the 376 Steyr and its wildcats, the 280 Ross and it's wildcats, 284 Winchester and its wildcats, and any WSM or wildcat thereof... that's about it. Other than that you're SOL. Sorry.

ok what are the choices with using 308 case?

.260 Rem, 7mm-08, .243 Win, .358 Win, etc.....pretty much anything with a 0.473 case head will work.

I have a 6.5x55, 7x57 308 and30-06 all on 98s. It depends what you plan to shoot. If something the size of elk or larger, I'd go 9.3x62. If up and including an occasional elk hunt, I'd leave it alone or rebore, not barrel to 30-06. capt david

Ok ! If you didn't go for the 7mmx57 how about a 22-250 or perhaps a 6.5X55? roger

well my comp been down so i haven't replied early but i really like the idea of 22-250 i need a varmit rifle

Whoa! now, be very carefull, you cannot rechamber a .308 Win. to a 30-06 unless you set the barrel back a good deal..You can re-barrel to about any caliber..

You can rechamber to a 284 for instance as it will clean up the .308 chamber or you can rechamber to an Improved 30-06, 35 Whelen or 338-06 improved...

Always check and compare chamber specs before running a reamer in a chamber and remember turning a barrel back always screws up the bedding in the barrel channal...Consult a good gunsmith and then proceed.
