Wow, you must see some pretty awesome vehicles from time to time then! I would love to see some pictures I'm cleaning my car this week and I won some 14 inch steels on eBay too, so I will take some pictures of mine soon
Oldest I've worked on was a '29 Buick, had to figure out wiring and repair a headlight switch. Lots of Beetles and vans, though the Beetles have been going away. I'm building a 40hp 1200cc Beetle engine right now, while a 2L van engine is also apart waiting for another case. I can do 60-year-old engine rebuilds one day, and figure out electrical gremlins in a brand new car the next day, I'm never bored!
Oh wow! That was going to be my one question, if you used that stock 10rnd mag. I was thinking you were loading some aftermarket high capacity mag. What a pain in the fingers. The 10/22 is one of my favorite guns I own to shoot. It's really fun and quite accurate.
My dad has one of those 25rnd magazines, but it was all plastic and quite worn so I didn't want to chance it. I brought it with me, but never loaded it.
There were 10 other 10/22's there today according to the range officer, all completely different. The one I'm using is an old carbine with a little scope, one of the range officers said it was nice to see someone using an old basic one for a change, lol. I did alright for my first time shooting rifle in easily 10 years (shotgun in that time), once I got used to the scope not being on center I could group ~1.5" diameter at 25yds.
I hear that on the dirty remmington ammo. I do have to give them credit where it is due. I got about a thousand rounds from my dad after that ammo went through a flood and was underwater for about 3 weeks or so. Not one missfire, jam, or anything from a Marlin semi-auto rifle. All of it was .22LR.
I'm surprised you didn't have issues. All of my Remington bullets spun in their casings. I Googled it before using any of them, apparently it's common and doesn't affect them (other than the mess). Yours must not have been loose and allowed water to get in! The only misfire I had today was a Philippine-made Ruko from probably the 90's, a few other Ruko's were lame but only the one misfire.
The Thunderbolts shot a lot straighter and more consistent than the old stuff I started with, but it was still not great. I just finished cleaning the crap out of the everywhere, even the trigger assembly was full of grits. The shooting table was covered in powder from the Remingtons, it was rather ridiculous.
