The crimp is necessary to get this to work correctly. It is all the way over the driving band. I tried a simple fold and velocity was only 712fps. My uncle shot handgun silhouette for years. He actually taught us this. He used the same bullet in 44 magnums usually with unique seated deep and crimped over the band. In some guns that won't get satisfactory results crimped in the groove you can deep seat them and reduce the powder charge and the instantly start shooting. My target velocity was 850fps. I reduced the powder charge and worked back up till the chrony showed 852 fps. Single digit ES. Very mild compared to shooting the Skeeter load in a Charter.

I was a handgun hunter, when handgun wasn't cool.....
