I'm getting super accuracy with many 25 and 30 grain bullets using H414 and WW760 powders and CCI450 primers. Berger's, Kindler Gold's, Nagel's, Hornady's, all have been well under an inch with the Berger's and Nagel's under 1/2". Shot two groups last night with the Berger 30 grain and the Nagel 30 grain T-000 that went 1/4" and 3/8" respectively.
