Project .450 Marlin KAR98

[Logan Lake Mike]

I have plans to build a .450 Marlin on a bolt action, and today picked up a small-ring KAR98 Mauser manufactured at the AMBERG arsenal in 1909. The action needs to be cleaned up but it looks sound and feels smooth. Are there any heat-treating issues with this early Mauser that may cause problems?

Should do fine I think. However, most people go after 11mm mausers and build 45 caliber rifle...

There is a .458x2" reamer in the EE, would be a great big bore Mauser project round.

I thought about the .458x2" ....it is nearly identical to the .450 Marlin ballistic-wise. However, with availability of .450 factory brass I won't have to form cases from other magnum brass. Mind not totally made up tho'. Thanks.

With a 450 marlin, that is the only source of brass--with a .458 x 2" you can make brass our of most any belted mag ammo.

Thanks for your input, guys, I'm now leaning toward recommended .458x2". Will discuss further with gunsmith. Mike
