I was at the range this past Sunday shooting a brand new VP9. Just got finished shooting 250 rds. of American Eagle 124gr. fmj with absolutely no issues. Figured I would finish out the day with running a bit of my normal carry round through it. I recently purchased this batch of Federal HST 124gr. and had fresh 50rd. boxes. I load up a full mag and proceed to fire the first round. Well.. it went pop instead of bang. Recoil was .22 like. I was sure I had a squib stuck in my barrel but starring at the target I had a hole in my new index card. I saw the slide cycle but barely. Case was still chambered. I cleared the gun and inspected it and the casing. All appeared good so I proceeded to finish the magazine the rest of that box and another 100 rds. The other 149 rds. worked as expected.
I know it happens and it could have been worse. All my actual carry ammo is case gauged or plunk tested in one of my HK barrels including the 150rds I fired. I am thankful this happened on the square range instead of real life. That could cause some real problems. I haven't contacted ATK and probably won't. Unfortunately I don't have the case lot # only the individual boxes are left.I thought hard about posting and may not be in the right spot (Mods please move if needed) but I figured it might be a possible bad batch floating around.
