Still tuning my "new" S&W Model 66 before taking it to the range. I think it probably has a couple thousand rounds put through it. It also had at least one catastrophic ammo failure, like a pierced primer or case failure, because there were blast marks in the area of the firing pin channel that could only be scraped off with a dental pick. "Had a blast, but made to last".

I'm pretty much done with the Ruger 10/22 takedown. It pretty much shoots the same, match-grade ammo or cats-and-dogs. A scope doesn't make much of a difference as far as group size goes, either. But it's now configured as a plinker with a Williams receiver sight (my eyes thank me), and can keep almost all the rounds in a scattered ten-shot group inside the ten ring at 25 yards.

The Ruger 10/22 target model will get a slight reprieve from ammo testing as I do a bit of experimenting with my CZ453 to see what it likes in ammo, and if it's as finicky a feeder as the Ruger. One combination of both Federal Champion and Ely Match produce outstanding results, while a variation of .00005" off of that produces ho-hum results.

This is the best group I've fired to date, even with the two "flyers". Ten shots, 25 yards, Ely Match sorted into .0385" rim thickness. I have not yet sized the Ely ammo because the bullets are coated with a thick lube, and I didn't want to disturb it. Sorting by rim thickness doesn't physically resize anything.

That .437" group comes at about 4x the cost of Federal ammo, but at least it produced one brag-able group so far. I roughly estimate that the Ely is about 2x more consistent than the Federal ammo. You gets what you pays for, if you're lucky.

Morning Win Mag - So the high priced ones do shoot better on average but at 4X cost it’s a no-brainer for informal shooting. IF I was a better shot I’d go for what won the day but keeping them on the two inch sticker at 25 yards is about my limit off hand. Kudos to small groups, flyers can be annoying. Which reminds me, buy more ammo and head to the range.
