Exactly. The problem is idiots who go into mechanisms that they know NOTHING about.
I cannot count the amount of maladjusted triggers I have seen. Just last week I had a Winchester Model 70 that would drop the firing pin just as the bolt handle snugged down. Have seen Rugers and Savages messed with that do the same thing. And Sakos and Brownings, Mausers etc. ad nauseam.
You bring up Rugers and I have to say thats one trigger I don’t like. I’m a big fan of the old tang safety Model 77’s but I’ve yet to be able to adjust the trigger to my liking, theres always too much travel. The ones that are not safe queens all have Timney Triggers installed. Bed them, float them and put in a good trigger and they’ll shoot with any factory rifle. My old 22-250 has been riding the ranch for many years. All my #1’s and #3’s still have factory triggers.
I hear you. But by having that 9 pound lawyer hanging off the trigger of the 700 it invited tinkering. They can be adjusted fairly easily, but you need to use a snap cap to check for possible malfunctions. Then, as I did, seal the screws with a clear nail polish.
