Some 8ga experimenting and info. The 8ga chambers
I have are set up to fire the regular 8ga
size cases, and also REM kiln cases with bases
turned smaller, where the extra short basecup
is formed over the inside cup.Just reduce to the
diameter that it chambers ok and regular case
doesn't expand very much fired in same chamber.
This idea came from UK 8ga hunters that found
it was easier to get kiln cases. Now the other
case in 8ga available is the WIN kiln case and
ones I've seen are only single thickness basecup,
but they have the step formed in them to match
the kiln case belt size. Now you can't turn them
down any to fit my chamber, BUT you can swage
them down .012" in a die with a lttle lube on the
basecup. Examining them they do expand much more
than the doubled up REMs.I fired REMs 4-5 times
with bases expanding .002", the WIN I did
expanded .005" in one shot. I will use
heavier built REMs as they are 70cents
primed and good for 4-5 shots, hairy loads.Ed
