i have shot lots of those bullets. and while they are a little dirty, there have been few ftf's. and nothing even remotely like what happened to you. for which i am happy. i have decided to buy winchester 555's prior to this post, not because of the ammo itself, just for whatever reason, my rifle likes the winchester better. i get groups that are about 30% smaller with the winchester bulk. i only have one partial box left of the Remington 525's, and i did check the lot number, and thankfully it is different. i have had some issued with 22 ammo over the years. split cases were the worst, but that was 20+ year old CCI mini mags. but on something that old, and not stored in an ammo can, you have to figure on having some trouble. i am glad you are not hurt! that is the most important thing. but things like this are one of the reasons i will not buy a cheap 22 firearm for my kids. i do not want them to have to live their lives without an eye. its weird, that the only rifle i own that i wear glasses while shooting is my 22. i have on problem shooting any of the center fires with naked eyes, but i have had enough junk come out of rimfires, that i always were glasses while shooting them.
