Accuracy problems with Ruger rifles? Not me. I have had 4 77MKII's. I gave the Ultralite 30.06 to one of my son-in-laws - is a good shooter. I still have a .308 stainless/syn which gives me 3/4" groups with Hornady 150 gr. SST factory ammo, a .308 RSI, and a 6.5X55 which shoot tight groups that I have not measured very precisely, or at least cannot remember right now.. I intend to shoot the RSI and Swede a lot more and reload more after I retire and have great expectations. After watching my friend shoot (5 shot, not 3 shot) .25 groups with his bone stock 77VT .25-06 (reloads), I have ordered a 77VT .308. To be honest, I think Ruger 77 MkII's are the "sleepers" amongst factory stock rifles - much better than most people realize.
Ruger's triggers have been much maligned and I have read 10# and 15# pull weights howled about on the internet. Mine all measured 6 to 6.5 lbs when I got them, and they were by no means terrible or unuseable. I happen to like Timney triggers, so mine all have Timney's set at 3# or slightly less, but the Ruger factory trigger can be touched up very easily and successfully. Some rifles benefit from some tweaking with the barrel channel - pressure at the tip or free-floating are common tweaks. The new Hawkeye trigger is said to be much improved, and the VT two stage trigger sure feels good to me as is.
In general, there is nothing about the Ruger design and construction that I don't like - even though I do think the trigger can be improved upon. Floor plate design, safety, bolt design, excellent scope ring system, wide selection of styles, chamberings, materials, and reasonably priced - I think the Ruger 77 MKII is far more than worth a little tweaking if needed.
I think read where Jon Sundra said that if he were designing a rifle, it would be the same as a Ruger 77. I pretty much agree with him.
