My new-to-me,10 year old Ruger has always shot so-so,for everyone who shot it. I had heard that if nothing else,a new hammer and trigger would work miracles. THEY DID Mounted my christmas present scope..Simmons .22mag..and headed to the range. Fired 1 fouling shot,and the next 9 chewed a nice ragged hole in the target.And this was with 'cheap' ammo..altho Blazers usually shoot pretty decent for me. Sorry,I got the trigger group on a trade,no idea what brand it is,but it sure helped. Next time out I'll get real serious and see if the group gets better.but heck,I'm still about this one ! the shots at the bottom are not part of the group..but might have been with the old trigger.
