I have used just about every kind of primer made and have had best luck with CCI BR primers in most of my rifles but when using a different primer you have to taylor the load some primers are a little hotter than some. So when primers were hard to get when nobama took over had to buy what I could find.
So Guys when changing primers work up your loads some times .5 to 1.0 grs. of powder will make a difference also you might want to change bullets. JMO
