22-204 with 40gr NBT's at 3950fps out of 22" sporter barrel, great wildcat simple neck up, no fireforming, no custom dies, great brass and you don't have to set back a 223 barrel to rechamber.
6mm-204 with 55gr NBT Lead Frees for those non-toxic areas, uses the same die as the 22-204 with the expander ball and bushings changed out. Rechamberred a 6x47 Rem barrel with the 22-204 reamer with a 6mm pilot
25-204 with 100gr Partitions at 2850 fps, matches ballistics of the original 250 Sav and 257 Roberts, my deer rifle. I had a custom die made as I built it the year after the 204 Ruger was released and Redding wasn't making the 204 Ruger Type S bushing die yet. I have used the Redding die to reload this with correct bushing and expander ball. I did have to open the die a little for the 25 cal neck.
22-250 and 35 Whelen, they were still wildcats when I started shooting, they built their reputation as wildcats.
I should get my 20 Practicle on tuesday, Thank You Ritch
