I have two purchased two T1X's now, and they both have shot < 1" groups at 100 yards with match ammo. Both my T1X's have exhibited issues where the spent casing gets stuck in the action.. like it will pull out but it doesn't eject out. Both of my T1X's have had to adjust the ejector spring.
This is done by unscrewing the mag well, unscrewing the spring, and slightly bending it so that it's a bit more pointier where it's pushing the brass out. This little 5 minute job has solved the issue on both of my T1X's and I haven't had a problem since.
My new T1X has had the vertical round happen once, in 500 rounds. Not sure why it happened, but even after removing that round, it looks like the magazine follower spring was off, and all rounds in the magazine were pointing more vertical. I had to take out all the rounds and reload the magazine. I think the vertical issue is with sloppy loading of the magazine, or something off with the magazine. But that only happened once in 500 rounds.
On my older T1X, I have had it happen once in 5000 rounds. And it was a friend shooting the rifle so not sure how he loaded the magazine.
It is a finicky rifle to get setup right to be really honest, but once setup, no issues in thousands of rounds... Out of the box shooting sub 1" groups at 100 yards for $470 is a pretty damn good deal.
As of today, I still say
If you have $500 - Get a T1X. Get a $25 stock pad from Amazon. Good to go.
If you have $900 - Get a T1X w/ a Bravo.
If you have $1100 - Get a B14R with a new Trigger
If you have $1800 - Get the MPA BA22
If you have $2400 - Get a V22.
