Rost495, CCI 41 small rifle military primers. Don't know if their a new product or not, have never seen them before. Have had the SS109 bullets for years, finally getting around to loading them up. Did a little internet research as can't find any date in my manuals for them. Results were confusing, had H335 set aside, but my research suggested that may not be a good powder with that bullet so bought the BLC-2. Did a little more looking and now can't make up my mind, was hoping someone had used either with good results.
