Thank you sir. Your added suggestions are very good. Using Federal Primers the way to go if reloading and the primer strike has been lightened to any extent. If you are using the newer S&Ws with the floating firing pins,(MIM guns) can even get better results in comparison to the older hammers with the integral pivoting pin. Some have added a small spring to the older hammers like the N frame hammers for even more consistent ignition on some of the harder primers. I know some of the reloading tool makers say don't use Federal Primer for liability reasons(CYA), but have never really heard of any real problems. I have been using Dillon for years and use Federal all the time for .38s and Winchester for 9mm. Remigton and CCI the hardest with Winchester and S&B next(my opinion)Making sure the primer seated right and bottoms out in cup important too.
Test and experiment and determine what will work best. Some advocate a "hard" strike for better and consistent accuracy performance.You be the judge on that.
