Have about 300 or so left, loading up some with Barnes bullets for my M70 Winchester .270, 40-50% don’t fire, significant dent in primer. Fact I’ve loaded .270 then .243 with same batch from same 100 lot. Not 1 misfire with .243. Off to the Smith here in Kamloops and Steve Jennings said nope nothing wrong with .270. Even showed him dented rounds and his feeling was faulty primers... once I explained the above he said John, I’ve seen a few unexplainable things over the years and this happens to be another one with primers. Just happy I was at the range for misfires.... and only 300 left Ican live with replacing them with different brand. Last bunch I used I think were Federals. What about Mag pistol primers in my long guns? I’ve a ton of those as I don’t pack my .44 S&W 629 for work anymore... sigh let the permit to carry lapse years ago now, dang in retro spect.... oh well. Any suggestions on primers appreciated Fellas.
Thx j

NOT a good idea the cups are not as thick and they may pierce in a rifle due to the stronger firing pin spring.
