The Great Thunder dud will it even go off test

Glad to hear the results. 500 rounds without a FTF doesn't surprise me. I noticed decades ago that the HUGE majority of rimfire FTFs were due to an issue with the GUN (usually light strikes or poorly shaped/positioned firing pin tips), not the ammo.

I went with the 5-10 based on my bulk experience with Winchester ammo. I’ve never had too many problems with Remington firing in a rifle though. Most cases were over 15 years old when they did fail. And most of those worked fine with a turn and restrike. I think a lot of rimfire misfires are due to dirty firing pins from the wax and powder residue.
