Meroh - I had one of these I picked up new in 2022. I've owned several Weatherby and Howa centrefire rifles, so it should have been a home run. The specs on the M1100 are fantastic and Howa does know how to build great rifles.
Without a doubt, the worst 22 I've ever owned. And that includes dozens of Cooeys, Winchesters (old ones), Mossbergs (old ones), Savages, Marlins, Norincos, CZs, TOz, and Anschutz 22s (OK, just one Anschutz).
If you look at online reviews from that time, they all talk about feeding issues and poor accuracy. Mine had all of those issues in spades. I tried everything to get it to work well and had a bit of success, but I found even the Scorpio I had at the time was far superior in every functional way.
I sold it to a rimfire guru with full disclosure of all the issues, and let him test it as much as he wanted. He felt he could fix any of the issues. He's a very knowledgeable guy with lots of rimfire experience and talent. After a couple of months he let it go in a fit of disgust to a third owner, also with full disclosure. Apparently it got moved on shorty after that.
Maybe the newer ones have fixed those problems, which would be great. I have bought another Howa since this experience, but a centrefire.
I would be curious to hear if anyone has had a more positive experience with the M1100 too!
