Does anyone have a new edition of the Sierra bullet load data manual?
Mine's a few years old and doesn't have data for the 123gr Sierra Matchking bullet in 260 Remington.
If someone could look it up for me,I'd really appreciate it.I haven't found much on the net.
Powders that I'd like to use are
Reloader 15 or 19
I just need the min/max powder charge #'s
