I had a Ruger M77 270 with the tang safety. It was a very good rifle but the trigger, like yours, needed some help. The last M77 i got in I ended up changing out springs and honing/polishing the internals to fix the trigger pull but it was a slow, tedious process.I like Ruger's! I have an old tang safety 30-06 that I have had great history with but the trigger needs help. I'll check out Wolf springs when the knee surgery is over and I can get around.
Our weather just started to turn to ice pellets and some snow flakes just started falling right before it got too dark to see.
I hope you have a great hunt stdt7mag.
