9mm "target" loads....

I have been shooting bullseye for many years....
Mostly .22 rimfire and .45 wadcutters.....
As I am aging, I would like to shooter softer loads. I used to shoot the S&W Model 52, but it was not as accurate as my .45. I later learned that the barrel was bad, and when the PC fixed the gun, it shot well. Meanwhile, I used the .45 and loved it. Inowhave a 952 longslide and would like to shoot it in bullseye.
anyone have some pet loads that are truly 'Accurate"....I need them to group 1" @ 25yds.
