Have found that if it is green, load american primers. They do not like the force fit of the oversize primers.
I use rem 209 but I also use fed 209----any primer works----feds are a little hotter---I'll bet that if you try any good primer -,you won't know the difference----JMO SJB
Been using Federals in my Remington hulls for many years. No problems, and you can cut the powder by a little.
Over the course of several years I loaded tens of thousands of Fiocchi 616 in Feds, Wins, and Rems of every sort and never had a single problem. And that was in three different 366's depending on the brand. Where I am the 616's are available and affordable. Never had any regrets turning to them exclusively.
I use Win 209. I have used CCI and Fed 209A. I have no problem with them. But remember that the Fed 209A are considered Magnum primers. I can always find win 209, but I can't always find the CCI. SO I stick with the Winchester version.
Locally the FIO 616 is about all that is available..... 3 stores sell CCI and Winchester. $40 a brick when they have them. 3 nearby clubs sell the FIO, $24 per thousand. I find with some STS or Nitro27 hulls one must use the drill bit trick to get full primer insertion..... Larry
