I was using Remington Thunderbolts .22lr. Maybe that's the problem.
Before I saw the rest of the thread I was going to say a good cleaning and change of ammo would be the first thing to try.
The remainder of the thread seems to have confirmed it.
Thunderbolt has been crap since about 2006 when they changed from the traditional "waxy" lube to a new shinny polymer coating, was an improvement when loading mags but a disaster when shooting
