Howdy guys,

I am wondering if I am properly crimping my heavy .357 Magnum loads (158gr bullet + 17 grains of Lil'Gun around 1540fps). I am a fairly green reloader and I still am figuring out how much crimp I need to apply. Here are some pictures of my crimp jobs as I just want some validation that I am doing it right. Also I am using a Lee .357 crimper.

Now I know I am using two different bullets (Speer 158 plinker + 158 Hornady XTP) to find an answer but both these rounds have two different crimps.

Thanks.
