Theres a lot of people including me with Remington 597 that have problems with jamming, some ammo jamming 70% of the time.
My mates Ruger is more reliable but I find the Remington more accurate, more ergonomic and nicer looking and a million times better trigger.
Most people say the Remingtons problem is the magazine, but I don't think I fully believe that as most of my jams are FTE, and supposedly you can fix it with a Volsquaren ejector.
I personally still prefer the Remington to the ruger, mine does function pretty well with Winchester Power Points which is made in Australia I dont know the exact figures of jamming but its pretty good, and strangely its the most reliable with winchester subsonic ammo.
But I think a bolt action is better, I end up using dads Norinco more and I plan on getting myself a CZ 452. The only real advantage with a semi I see is the ability to waste ammo quickly, which I guess ain't exactly a good thing but nothings good these days
Oh and I don't know what the rugers like to clean but my Remington is a pain if you completely take the bolt right out, the stupid springs on the two rails are a mission to get back on, it is possible. I dont think im a very good Remington sales person am I, Id defiantly get an AK47.
Oh wait this thread hasn't gotten into that yet
