Hello

Just need a second opinion here. Planning on taking a left handed short action with a 308 bolt face to a 7 saum. I go to midway and the only bolt face that seems suitable is a controlled round feed bolt face? Something change here? I took a 110 from 270 to 300 wm a few years back and just replaced the push feed for a mag pushfeed.

I know I may need to change the mag box and follower but any insight for the bolt head would be appreciated

Thanks
