Re: mauser 98
Bummer on the dies. Suggestion: If you have to have dies made go ahead and get them done by one of the recommended smiths here who will match them to your chamber. Might as well do it very right if you have to do it to in order to use the rifle. Also will help to keep the brass life up.
Have you had the barrel inspected already ( rifling, throat, rust/pitting, etc)? Only reason I ask is because I bought a Mauser once and found out the barrel was all jacked up. Ended up going to another caliber before I got too far into components and dies thank goodness. May be good insurance to get the trigger installed and everything inspected before you go too far with the dies, etc.
