With all the cold and wind lately I started to get my reloading done for summer. First thing to do is load the bucket of 9mm. This is a mix of range brass . Using my 356402/ 4.2/231 load with Tula primers. That darn s&b brass will jam up the 550b most of the time as the primer will not seat flush or just get started in. This wastes a primer and jams up the works!Clint
