Peter K. Bowser –
#1-1/2 is an old designation mostly used by Remington. I haven’t seen where Winchester has used that. They should be your normal magnum small pistol primers usually used in .357 magnum loads.
Jose G. Cole –
Definitely a primer of choice for my .357 loads. Consistent performance and reliability. This primer appears to be a bit harder than the CCIs. Seats consistently. Provides lower standard deviation (SD) readings on chronographed loads than some of the other primers I’ve tried. A good performer!
Jimmy T. Vogan –
Winchester small pistol magnum primers work great for my 357 magnum. Have never had a misfire.
William A. Johnston –
100% reliable all the time. Consistent good fit in my 357 brass. This is all I have used for decades.
