7 SAUM, am I on the right track here?

[WhiteRubi]

warrbuk...correct. I'm looking at an Anti X that is cut specifically for the UM bottom metal

 

[Longtine88]

We have it covered, I think. So a new question. In a short action and the UM bottom metal and their mag, I can load to approximately 3.15"
I know, now, that is fine. So if i plan to mainly shoot 168 and 175, and MAYBE 180s, how do I address freebore when getting it chambered?

A .200 freebore will get the 180's at 3.130" coal.

I'm going medium with hawkins hunter
Dbm. If you are building a custom from scratch I can't see going short action. I mean you can make it work but why limit your coal.

Yup.

You'll be ok, but very tight. As far as freebore cut you'll just need to provide your gunsmith with a dummy round. I'm guessing you will probably want to end up with something closer to .180 as the .200 won't allow much flexibility because of mag space
