Spent the early morning hours today on the range

testing some new loads thru a 50 yr old varmint gun. My early 70s Ruger Mod 77 in 220 swift, still has the ability to shoot one hole groups. The problem lies with the 77 year old misfit on the trigger LOL. The best 5 shot group,at 100 yds, thru the chronograph, this morning.
