Went to Wally World to by grocs. and of course look at their ammo selection. Here's the oops, wow they had ammo. Thought I was buying 6 boxes 22WMR turns out they are 17 HMR. I noticed this a week later. Some stores I've seen posted no ammo return. I hope WW doesn't have an issue. I' ve been looking at the Fn 5.7 off and on and these rounds remind me of the FN's. If I can't take these back maybe someday a handgun will turn up with a very small muzzle that will shoot 'em. I should learn to read.
