Testing Rocky Mtn cases in NEF.Got 1850 fps
with 125 gr AA 1680 and 132gr of RE-7.
Cases are 2.9 after 3 firings. AA 1680
load had .135 card wad and 2 1/2 in lubed felt
wads, and RE-7 load had same card and
a 1/2 and a 1/4 lubed wad. Re-7 less dense.
Base expansion ahead of thick base was
.002 to .003 and resized without huge effort.
The base is .300 thick, case has shotgun primers. By the way I put primers in with
bmg primer post. Work good. Now will cut back
some cases for the 87 levergun.About same
loads used in NEF minus wads should do.
Will get little less velocity in 20 in bbl.
But I will have loads figured out for
a bunch of guys here and in Australia.
I also feel now that have I found loads that
get velocity without a huge expansion, to
the turned cases that good low base plastic
will do the same velocity, in strong alloy
barreled guns. Ed
