I've used small pistol magnum primers for .357 in the past. But now with none in site my only option is the std primers. I have CCI no. 500, and Winchester WSP. How do you think it might affect the the way it shoots? I'm loading up some Hornady 140 gr. XTP's with 16.6 grains of H110. How much difference do you think there will be between the ones I've loaded with magnum primers, and the ones with std. primers? Thanks.
