Results of RE-15 testing in plastic cases.
600 gr hardened Dixie slug and 10gr
of Blue dot starter powder in both lengths.
In Nef, 3 inch case is about 2.6 crimped,
and 120 gr RE-15 max load. In 1887, 2.75 inch
cases are about 2.35 crimped, 110 gr RE-15
max load. In 2.75 case thats all it will
hold,with card wad, in longer make up space with wads.The reason I'm checking plastic is so many shotgun reloading guys want more power for big game, and they are set up to
load plastic. With starter powder- a caution.
You must put starter in keeping case level,and the powder put in on top, must be put in slow
so as not to push it away from primer.
Greg Sappington clued me in on another powder that may do the job without starter powder
and be slow enough to get velocities up
without to much pressure. It's IMR SR-4759.
Will have some in couple days.I made contact
to get some of these loads pressure tested,
to check my pressure calculations..Ed.
