Went to the range today to try out a 30-06 rifle, and while there, fired the 15-22, as well, just to check reliability of the little 22.
In order:
25 rounds Blazer, no issues.
25 rounds Winchester Super X Hollow Points, no issues.
25 rounds 550 Federal Bulk, 2 FTEs.
25 rounds Winchester Super X Round Nose, no issues.
25 rounds Winchester 333 bulk, no issues.
25 rounds American Eagle, no issues.
25 rounds Blazer, no issues.
25 rounds Winchester Super X Hollow Points, no issues.
Today's rage trip mirrors my experience with the 15-22 and the ammo I have. The gun really is not a picky eater, but the Federal 550 Bulk Pack is the least reliable ammo for my gun. An average failure rate of 10% is what it produces for my 15-22. Considering I have about 3000 rounds left of the 4950 rounds I scored on Thanksgiving, I think I will live with it!
