If he means the .17 Winchester Super Mag he did get in the right sub-forum here. Rimfire and smallbore would correctly describe that cartridge. As far as knowing if it has been discontinued, I have no idea.i think that you missed that shot by a couple of feet and put it into the wrong group... adjust your scope sir!
Nope I have had bmags for 3 or 4 years.Alive and well. Savage B-Mag just came out this year.
Not real sure what your information has to do with .17WSM, as the OP originally posted. ????one thing that surprised me last week is i went into sodak sports in aberdeen sd and they had 10 boxes of 17 hornet and runnings had 4 boxes.. bought them all.. sodak always has good stuff.. 25 bucks a box
