Hello,
I have a SW 500 mag with a 4" bbl. My handloads misfire fairly frequently. When I say misfire, I mean that the primer is fully contacted and dented and there is no detonation of any kind. No hangfires either.
I understand that there is confusion about large rifle vs. magnum pistol primers, but I have both types of brass and have fully experimented with both types of primers. It makes no difference. I have taken great care to clean the primer pockets, allowing for maximum primer seating depth, but this doesn't seem to make a difference either.
At first I thought there were issues as follows:
1. The primers are not appropriate for this load. However, I've experimented with Winchester and Remington primers in all combinations and it doesn't make a difference. I have not tried other brands though, mainly because I have zero misfires with any of my other handloads.
2. There is a defect with the gun. However, it shoots factory ammo just fine.
I have been reloading for 20+ years and I reload for 15 different calibers across all types of actions and systems. I don't think I'm an expert, but I'm pretty experienced. My other handloads work great, so I'm really at a loss!
Has anyone experienced this issue with their 500 mag, and found a resolution? I am being driven mad by this! I simply can't figure out what the heck is going on!!
Any help or insight would be appreciated. Thanks.
