well if it does get stuck bad put it in the freezer overnight doug,l have been using jb weld for bedding rifles for years its the same basically as devcon, impervious to all solvents and oils,try putting a light coat of vaseline everywhere on the action and then use one large piece of saran wrap around it and carefully put the action into the stock and it will give you a great finish.
You will have no problem going out to 700yds+ with a 154gr SST out of that short magnum. use what ever you want and go for it. Only thing to consider with the lighter bullets (120gr, etc) is impact vel.
As long as impact vel is under 2800fps, almost all softpoint bullets are going to work. If going for super speeds, you are going to need a Barnes X or Partition. The SST are quite a durable bullet but I would not expect them to hold together if impact vel is much over 3000fps.
Jerry, Did you read OCT. issue of Shooting Times, the one where they tested all the 180gr bullets? I remember the SST fired at 3000fps retained I think it was 76%, with no core separation or anything like that, pretty impressed I was, basically the same weight as the Scirocco, not to bad for a nonbonded bullet. Maybe the 7mm would behave differently though, I don't know. [img]images/icons/wink.gif[/img] Jay
