redding Posted September 7, 2022 Report Share Posted September 7, 2022 Hi I have been forced to switch from S&B large rifle primers to Remington 9 1\2 Magnum Primers due to supply problems. The round is .308. My original load was 47 grains of RS52 with S & B large rifle primers which gave me good accuracy results with a Barnes 130 grain TTSX. Now I have to use Remington 9 1\2 Large Rifle Primers. My question please, is there any advice on powder charge weight using the same powder, same (Hornady) cases, I am thinking about safety.

John MH Posted September 7, 2022 Report Share Posted September 7, 2022 Difficult to say but I'd recommend reducing your charge to the minimum recommended in a Reloading Manual. Quote Link to comment Share on other sites More sharing options...
redding Posted September 9, 2022 Author Report Share Posted September 9, 2022 I developed a load that was printing ok. Problem now is out of 10 loaded rounds 4 misfired, remington 9 1\2 magnum large rifle primers, thats 40% Anyone else having issues with Remington primers. Just called a gun shop to enquire about alternatives, he has some Federal, I asked him about Remington primer problems and his comment was "bin them" This is a picture of the misfired rounds, obviously there is nothing wrong with the firing pin and they were seated as deep as they would go. Never had a misfire with S&B primers in 4 years! Quote Link to comment Share on other sites More sharing options...

Woodlander Posted September 18, 2022 Report Share Posted September 18, 2022 Federal are good primers, wouldn’t expect any issues with them. Quote Link to comment Share on other sites More sharing options...
