I am using standard fed210 primers in my 460 loads but I am using Alliant 2400 for my powder. My 460 is a TC encore barrel however and my TC has a beefed up hammer spring. I have had some light strike issues with cci 500 primers in my Taurus 357. I have also heard that cci primers are harder to strike. I plan on getting some different primers for my 357 loads and trying that.
