Gunsmithing Magnum 700 action, what to build?

[cast1]

I've got a magnum boltface long action 700 on my hands. What should I build with it? I've thought about a 300 win mag, but have also considered a 30 nosler. What 30 cal, or other magnum would you guys do?

Thanks,
Shep

Go check out the Vintage Section... the thread on Mk13 Mod 0. There are still a few stocks available.

Just 'sayin that all the cool kids are building them

Whatever you build... sounds like a fun project!

Cheers,

Sirhr

I guess you call your choice of vendors. I have a particular setup we've found to work but I don't openly share it. Getting this cartridge to run correctly/safely took a little effort and a fair amount of money. I can spin one up for you easy if you like.

I should probably have specified that I would be doing the build. Chad is a genius and I appreciate his advice. I thought perhaps this was a commercially available spec reamer. This is a hobby for me and a livelihood for Chad. Far be it from me to expect him to give away what he's put sweat equity into. I'm leaning toward the 28 nosler after looking at it. Maybe I can get info on the mk248 in the future. Keep the input coming y'all.

have the same build in a 300win mag...loving the round. Plus I know a guy who shoots this stuff for the gov....I get a few boxes of the stuff that "fell off the truck"

Sorry for the slight derailment but is it a different reamer than the "normal" 300WinMag? I would assume (yes, I know what assume stands for) that it's a different freebore to accommodate the 220g MK's. Is there something I'm missing?

Mark 248 mod 1 like chad said. You should try to work something out with him. Chad whipped one up for me and holly fuck. Incredible. 230 bergers runnin 2960. Accurate as hell.

Lol chad would have to be willing to give away his trade secrets. I don't expect that. I wish I had something I could trade him for the info.
