For me, the biggest advantage to having some kind of 22LR barreled action that you can drop in Remington 700 stocks/chassis is the ability to show up to an NRL22 or PRS22 match and get some cheaper, easier reps in on stages that are hard to practice on your own. Things like large props, or if your local ranges don't allow positional at all, then ANY props. It also cuts out the reloading aspect if that becomes a huge time suck.
It's been a year or more, but at least on the NRL22 side, the longest shots were around 150 and the targets out there were large enough that regular SK Rifle Match out of a Bergara B14R could hang, no problem. When you get into the ranges at NRL22X (and although I've never been, I see that PRS22 also goes out to 300ish yards) then yep, you'll have issues solely due to mechanical accuracy of even nice match 22LR, and that stopped being fun and started to look real expensive to me.
If you can set up props at your range, or your range just has them out for you to use, and are looking for a practice rig? .223 seems like the easy button.
I'm fourtunate to live in a part of the country where there's a centerfire match almost literally every weekend, and the NRL22 match that's close is only once a month and got real popular, so I haven't been in a while.
