Playing around with some ideas for a build. Looking at either a 7mm SS or SAUM and heavier bullets with the 175gr EldX as my first choice bullet for hunting and want to seat the bt/shank junction of the bullet as close as possible to the neck shoulder junction. Ideally want to mag feed and be able to eject a loaded round. Will this be possible with Terminus Zeus action for SAUM or will I have to go the SS route and is it possible with the SS? What mags should I be looking at? I assume the Terminus would be suitable for hunting?
