I've been using CCI's and they are just fine but I've not found them at a reasonable price. How about Wolf, Tula or S&B or any other brands? I've used S&B and Wolf in my pistol rounds just fine. Are there any brands to stay away from?
I use the Tula LR Magnum Primers to load jacketed full house loads for 375 H&H, 416 Rigby & 458 WM. I have had 100% success with these primers. I haven't tried any of the other Tula primers or the S&B or Wolf primers.
Winchester primers have always performed well for me. They provide consistent ignition from batch to batch in all calibers that I reload and have never let me down. Their large rifle primers are all I use for my 45-70 reloading.
