As I mentioned, I put a Timney in my Hawkeye. The stock trigger had been too heavy, so I got the spring replaced. It was fine like that. I just wanted to see what the Timney could do for me. It was better, but not by a lot.
The grandson's 308 tang safety has a wonderful trigger. Per his uncle, who gave him the rifle, the trigger is pure stock with no modifications at all.
My tang safety 220 Swift has the original trigger, though I had the pull lightened. It's great, but real light.
Dad's old tang safety Ultralight had an awful trigger. I guess 20 odd years of hunting in bad weather without ever cleaning any part of the rifle must have caused that. When new the trigger was fine.
Back to my 223 Hawkeye. It turned out that the basis of my accuracy problems was the Nikon Monarch 4-16 scope. I spent money to fix what a new scope would have fixed. The Nikon was also pretty new, but had a mildly wandering POI. About drove me crazy till I figured out what might be wrong. Oh, well...
