You can build with a flat rear long action, but I am willing to bet that you will have a better time feeding with a newer long action that has a centerfeed magazine box.
The only hindrance of the flat rear actions are that they were only made with staggerfeed type magazines and that sometimes the flat area is not perfectly true with the round front area and sometimes makes scope mounting an issue unless you are planning to bed a 1pc scope mount or are planning to use Burris Sig Zee rings with the adjustable inserts.
