I recently purchased a Remington 597 AAC-SD "tactical" 22 semi-auto rifle. It has a 16" threaded barrel(I installed an A2 flash hider). Great looking rifle, but not as accurate as I expected. Has anyone else had experience with this rifle? What ammo does it like? I have tried Winchester and Federal 36gr. h.p. ammo with mediocre results. It will drive nails with CCI subsonic, but will not cycle the action. I need some advice before I buy a bunch of 22 LR. Thanks

With my buddy's 597, he needs to clean the chamber about every 50 rounds with a cotton swab, or it won't cycle anything. That might be its problem with the CCI.

The subsonic CCI at 879 fps is too weak to cycle. The rifle cycles other bullets fine. The accuracy is not good enough though.

I own a 597 and it is very accurate but very unreliable.
There are two main causes for it unreliability, the magazines and the extractor.
The magazines are made of die-cast aluminum and are unfinished, they get dirty and crud-ed up from the ammo and also from powder residue. This causes the rounds to not strip off the mag consistently causing mis-feeds. One of the remedies I found was to clean the the mags periodically with a brass brush to polish them and remove any crude and oxidation. But this is a PITA!!!
The stock extractor is a cheep piece of stamped steel with a machined edge that wore out in about 600-800 rounds. It would hold onto the case for just a bit slowing the timing and then stove piping when the bolt closed. I replaced the extractor with a Volquartsen extractor and that made a huge difference.
When shooting decent ammo there is more consistency and I don't get as many stove pipes. However when I shoot bulk box ammo (Federal, Remington and Winchester) the rounds are not as consistent throwing the timing off causing more stove piping.
Since this gun is a POS I don't feel bad about messing around with it trying some different ideas out on it. So I replaced the recoil buffer with very hard one trying to slow the timing down. It has seemed to work.
Now I back to the crappy magazine feeding issues.
I hope I didn't ramble to bad.:o
