Redding FL dies don't have a air bleed hole like RCBS dies do!
I got out the 264 Win. Mag. box of dies and brass to get that rifle going. I found the decapping pin gone from the RCBS box and a note saying to find it in the 7mm WSM box.
There was a Redding box right there for the 264 ready to use. I put the Redding FL die in the press instead and the first case got a big dent in its shoulder.
No air bleed hole!
I found the decap pin for the RCBS dies and put them to work.
No dents.
