I've a 338 Lapua that I finally shot this weekend. Maybe it's normal (though I'm sure it's not) but I noticed wen shooting that I pull the trigger and I hear the firing pin hit before monster bang. I reloaded my own rounds to sight it in with and it's the fist I've done for the 338 so maybe I jacked something up. Dunno. Lapua brass, 87 gr Magpro powder, federal primer, and 250 gr hornady bullet. Any ideas or insight? I've got a video I can post later where you can hear it but can't post it from my phone.
