I guess the only thing you have to make sure of is the bottom of the action contacting the stock (not the tang, the area immediately around the action screws). That will tell you if it is seated deep enough. There are several things you can do to see if this is happening. Coat the bottom of the action or the stock with something thin that will transfer to the other part to see if it's contacting. If everthing is making good contact and the action setup feeds the ammo correctly then I would say there is not too much pressure on the magazine shell. Above all.....if it checks out, go out and shoot it.
