I guess I am lucky like Coyote Hunter. I have three 77's that I have shot and all are around an inch or better from the bench (2 .308s and a 6.5 Swede). I am a hunter and an inch is better than I can shoot in the field, so I don't take the accuracy issue any further. Maybe I could tweak some more out of them - don't know, maybe I'll try someday. I am happy the way they are. As far as triggers go, I like about 3#and crisp. I have installed $60 Timneys in my model 77s and adjusted them to 3#. I have a new model 77 that I have not yet fired or installed aTimney. I checked it today with my two trigger pull gauges. It is 6# not 10#. I never kept records, don't know if I even checked my others before installing Timneys, but this one feels about the same so the reference to a 10# trigger, in my experience, is an exaggeration. The trigger pull is not really that bad on this rifle either, just heavier than I like. I have been shooting and hunting for over 50 years and I have dealt with triggers that have been much worse. I don't like a bad trigger, so when I can, I work on them or exchange triggers. A good trigger is a joy and does contribute to better accuracy, but I could do very well for the rest of my days with the stock 6# trigger that exists on my newest model 77 and won't lose any game because of it. Certainly benchrest shooters (and me, when I shoot at targets), would rather have a lighter trigger but to condemn the Ruger is in my mind, not entirely fair. I really do have other guns (like a bolt action 12 ga. slug gun) that are far, far, worse. I get inch and half groups with Federal Barnes sabots with it consistently, and have taken many deer with it, so triggers don't make or break a gun for me. (If there was any way to improve that slug gun trigger I would - but I'll live with it otherwise because it is a shooter.)
To mix Mini 14's, #1s, and 10/22s into a comparison that is related to 77's and Tikkas is to me quite a stretch. The Mini 14s and the 10/22 carbines were never intended to be target guns. Some shoot far better than their reputation, but I believe they generally live up to reasonable expectations. The target model Ruger rifles I have owned, used or seen have in my experience, lived up to expectations. I have a Target 77/22 and a Terget 10/22 both shoot with anything in their class. On the 77/22 I put in a target sear - wasn't bad to begin with, but very nice now, and the Target 10/22 is fine as is. On my 10/22 carbines and other rifle, I install a target hammer - nice improvement. My 10/22s shoot to my expectations, I enjoy them.
I said it before - I look at all design features in a rifle, not just the trigger, and I like the engineering in a Ruger 77 MKII. The Ruger's styling, fit, and finish is fine with me as well. To me the Ruger is well worth the little effort to improve the trigger. The only service issue I ever had with Ruger (on a Blackhawk revolver) I found their service to be excellent. I like my Rugers very much, and feel no need to disparage any other brands or opinions.
