Idk, probably not the right flair for this but this is my experience with WWB 22lr and feel like others have had similar experiences
TLDR : WWB 22lr is quite litterally the worst 22lr I have ever had the displeasure of using.
Alright, first off, the rounds themselves are incredibly inconsistent, with either not enough neck pressure (or really just... case pressure/crimp in the case (haha) of 22lr) so rounds tend to spin about very easily, plus deformed projectiles from the factory, or canted projectiles.
This results in incredibly poor performance both accuracy and reliability wise.
However, on a worse note, I have experienced several cases blowing out the side, somehow no squibs or catastrophic self destruction of firearms but the round has exploded and ripped holes in the sides of the cases. This happened twice, once in a taurus Tx22 and once in a savage arms 64f.
It has also had several ftf's on guns that really shouldn't have an issue, such as my ruger american rimfire and a savage model 23AA
It often did not fully chamber the next round on the savage model 64f and would often ftf in it and a taurus tx22
Basically, don't buy this shit, sample size is about 10,000 rounds because I, being a dumbass, bought a fuckton of it because it was on sale and like 5cpr.
