Guys,

I am getting pressure signs way too early in my 460. I admit to being new to the cartridge, but haven't run into this before in reloading.

Here's the story:
Hornady 240gr xtp mag. Starline brass. WW296 powder. Fed 215 primer. I'm running to way too much pressure half way up the load data scale. I am assuming it is the Fed. primer. It may be too hot. Has anybody else tried the primer?

Thanks
