12GA rifle From Hell--

[hubel458]

Some newer slug ideas coming around. First is Brenneke,
a locked on base ounce slug in sabot at factory speed of
16-1700 or so in 3" plastic.Really go in our 3.5" loads.

Second is Federal Deep Penetrator, 1 oz, copper plated
and a harder lead alloy, than Federals regular slugs.

Third is Dupleks, steel slug riding on a plastic band,
penetrates very well. About 1 1/8 oz.

Seeing the slug base attached deal from Brenneke,
in a sabot I figured out the following.

The idea is the new BPI blue sabot, being undersize for
12ga, is a perfect fit in a 10ga bpi wadcup, The blue has no
cushion on it so it sits in cup ok and a roll crimp works.
Just shaved bottom edge corner and fits bottom ok.
In 32" heavy barrel NEF 10ga, and 10ga 3.5" plastic case,
gets over 2300 at less than mag shotgun pressures
with 440gr slug in blue sabot.I plan on in future to
make a 10ga with rifled barrel, which these would be best in.

If I can find thin wall 10ga wadcup the 12ga bpi AQ slug
would work even better, as it is for smooth bores....Ed

Here are pictures of the full bore Lee Key Slug
I had a guy cast. He took Lee Key mold and machined
it out to cast a .729" full bore slug. In picture
is a regular soft lead Foster style to compare with.
Slugs are hard alloy and can be speeded up ok.
In 2nd picture is two MRC 2 5/8" brass cases with
slugs in them. These slugs with those brass cases are
being tested first in rifled barrels in a guys 1887 WIN.
The slugs have real good shoulder to
roll crimp against when used in plastic cases.
These first ones are 500 gr. We are going to
work on another die to get the weight about 600gr,
that the brass case guys want to use.
Lee molds are not real high price so it isn't
a bad deal to get them and change them.Ed.
