I know that compulsive disorder... I believe it's called exhaustive-propellant-brimming disorder... I used to suffer from it until I realized I could no longer convince myself that it killed things deader. But it lead to the next disorder which, as adding more powder didn't kill 'em any deader, then perhaps a larger bore and more lead is the answer to making an animal ultra-super-stone-cold-bucket-thoroughly-kicked DEAD. Haven't talked myself outta that mentality yet.
I have several CZ's and really haven't had any feed issues. Action is a bit rough but really didn't bother me. Actions are definitely smoother than the old BRNO's I have. I used to drive my mum nuts when I sat in front of the telly racking the action whilst watching hockey. I found the more you shoot the BRNO & CZ's the smoother the action gets.
Regarding the OP's question. The CZ 550 416 Rigby I have I bought 20+ yrs ago. It is the straight stock version. Haven't had an issue with it except it "jiggles the fillings" pretty good. Did a nice job on a "big tusker" groundhog that tried to defy a 400gr RN at 20yds
I purchased the same model for my DG hunt in South Africa a few years ago. Price point was a big concern and wanting a crf, hence the CZ 550 choice. It took a bit of polishing while watching hunting videos, trying to get as much info on DG hunting. One thing I found while reloading rounds, I used Hornady DGX 400 gr for practice and sighting in and they did not feed well, I think it was the profile of the bullet itself on the feed ramp. As i was not going to be using them for hunting it was not a big concern. I chose the Swift 400 gr A frame and 400 gr breakaway solids. they fed without any issue. Both the Hornady and Swift loaded rounds were the same C.O.L, for what its worth. Have fun and enjoy your new CZ
