I like the older 77 rifles, always have but the triggers were never good and I HATE the internal magazines. Dropping shells everywhere…
The trick to making my 308 shoot right was a Timney trigger.
My old tang safety M77 has had the trigger worked on by a gunsmith and it's good at about a 3 lb pull
I put a timney on my M77 Hawkeye and it's fantastic right at 2 lbs. Unless you're good with a metal file do not attempt to install this trigger on your own.
