Hey guys, total newbie here when it comes to a specialty handgun. I would like to either build or buy one in a 7 wsm. Was just wondering what my options are ....build on a xp100 or would a guy be able to do something off a savage action, whether it be a short or long action. I do have a left hand long action sitting around and I would be able to load the wsm really long. I am looking at loading the 162 Amax or 180 Berger. Not sure what velocities I would be reaching but will use this for longrange deer and antelope. Thanks a bunch guys!
