I used to shoot a lot of Ruger rifles. I've had both extremely good and extremely bad luck ... more variation / less consistency than with Remington.
I've had two Ruger 77 (mk IIs) in .338. The first one shot great after I replaced the factory plastic stock with a Ramline synthetic. With 210 grain X boat tails (moly coated) it'd shoot in the .3s. The second one I just traded off. It was the laminated/stainless configuration. Accuracy was acceptible out to 200 yards but something funny happened between there and 300 ... nice round groups suddenly strung horizontally in both directions.
I _realy_ liked the way that 2nd rifle felt. Compared to the Remington 700 LSS in .300 Win Mag which took it's place, the .338 was noticibly more comfortable to shoot in terms of felt recoil.
Replacement triggers are a bit of a problem but it's no big deal to get one that's of fair hunting quality. Not a BR competition trigger, but good enough. I put a Timney setup in mine which had both new trigger and sear along with some springs. I'm not a Timney fan, but their Ruger trigger is a noticible improvement over stock.
The previous 77 mk II I worked over using a combination of 77 mk II and 77/22 parts. It ain't officially approved, but so far as I can tell the two rifles use interchangable sears. I dropped a Volquartsen 77/22 "match" sear with the gold titanium nitride finish and a Dayton Traister M77 mk II trigger into the first Ruger .338, did a little stoning and fitting, and wound up with a 20 ounce trigger which I thought was a good balance, light enough for decent shooting, but not too light to handle with wet cold hands.
Anyways, for a .338, if I could get one that shot, the Ruger 77 is probably my favorite choice of rifles.
