  1. Buddy Smith (verified owner) –

    I picked up a few hundred of these to try out and have found a really good load that works for me and my pistol. I wanted to share this for the next guy so it might help save some time and ammo. The following load works for me and my pistol and I suggest you work up your own load that is safe and works for you. With that said I found that 5gr. Of CFE 223 pistol with A CCI small magnum pistol primer, hammer 137gr. Bullets and a seating depth of 1.100 shoots very well. My 4” barrel shoots these at 1100-1120 FPS and has great groupings. Hope this helps and thanks Hammer for the great products!
