Remington makes some really bad bulk .22 ammo, it's really shameful that they put out such a lousy product. Thunderbolt is dirty, not very accurate, and not very consistent, Golden Bullet the same. That said, I got a few buckets of Golden Bullets during the shortage to keep my son on the trigger, as well as Thunderbolts that I've had for a while, and we have not experienced that rate of duds, not even close... Just a guess, but maybe one dud every couple/few hundred rounds, maybe...
I mainly shoot CCI standard velocity, Aguilla, and Federal, and have had good results. For competition I've had great luck with Eley Tennex and Match, and even Wolf. I bought a case of Wolf years ago, and it is very consistent and accurate. At the time, it was a great value, but much more expensive these days...
For less expensive fodder, Blazer and Federals have been very good... The Blazer has been surprisingly good in many of my rifles. I know some people don't care for it, but this cheap (had bought a bunch prior to the "Great Shortage") Blazer really performs well for me, maybe I got a good lot of it...? Winchester Wildcats have been not so great (but better than Remington), and Winchester Super X and Target has been ok. As always, YMMV.
