I sort of have a general rule of thumb, if I am loading a charge of 60gr or less I use a standard rifle primer, if it's over 60gr then I switch to a magnum primer, my go to primers if I can get them are Remington 9 1/2 and 9 1/2M and 6 1/2 and 7 1/2 BR in my small rifles, but I have used federal and CCI and even Winchester over the years, to be honest I could never tell the difference between primer brands.
Anyway just my 2 cents worth, do a little experimenting and see what works.
