See my post from last night under "range reports." Had multiple failures to fire due to hard primers WITH GOLDEN SABRES. Not sure how old the box was...could have been 5 years but suspect much less. These occurred in my new Covert but I then switched to my older R9S and experienced the same problem. If you wish to carry Sabres, would recommend firing part of the box through your R9 to be sure about the primers.
