      Hi Guys.

      Does anybody have a current ranking of rifle primers and their power?

      I’m working with a 375 Ruger and I’m getting some Hangfires.  I’m useing CCI Mag Rifle Primers with CFE223 and the 235 Speer bullet.  I can’t find and Fed 215s anywhere.  I was at a middle of the road powder charge, so I”m going to try to step up the powder and see if that helps.  If not, I’ll try switching to H4895.  I would like to use one of the modern powders so it would be less temperature sensitive.

      I have not used CFE223  –but thought it was best suited to the smaller cases

      I have used CCI reg and Mag primers in 7mm mag (60 plus g of powder) and not had a problem

      as well as using them in smaller cases —

      So I think it is the powder / case size / pressure combo giving you problems using  CFE223 in the 375

      I think you are on the right track switching powder

      another point is you will also get more rounds per Pound using a different powder

      Since I use a lot of surplus powders, I’ve pretty much switched to Winchester primers to help avoid inconsistent ignition. It’s not just the power, it’s how they ignite the powder. The Winchesters use aluminum powder to help ignite the powder. I haven’t heard of any others that do, but I haven’t heard much about the specifics of any, which I imagine are trade secrets.
