What have you used that you had problems with?A good powder for the Ruger 204 that is temp resistance
How do you like the AR match primers? I picked some up last year from someone and haven’t tried it in 204. Only been using 7 1/2 and 205mStarted out with 10X, then IMR8208, and now trying VV N133. All with 40 grain bullets
Switched from Remington 7 1/2 primers to the new Federal GM205 Match AR primer for my 204 Ruger.
