I have a short action magnum I bought about 6 years ago, 300 WSM with lilja barrel. The action is rough, not smooth like newer actions. However, the accuracy is good. With my own loads, I can get very tight groups. This is not an action ready to go, it requires work by a smith.
I wouldn't discount the action, talk to MRC, maybe improvements have been made. They have excellent customer service. It is a tough action, not meant to be a long range or bench gun, but is a great action for a hunting rig. If they do a little work on making the actions smoother, I would certainly buy another.
It has an integral recoil lug and controlled round feed. Very hard to find at this price....
