I posted a little info on the tri-ball thread, but don't want to hog it,
but yet we are group of experimenters want to pass on the years of
info and pictures to all gun nuts around the net.
My name is Ed Hubel and over the years I and others have worked to continue
development of the 12ga From Hell and other big bores, and have posted info
all around the net about our research and many ideas we have implemented for
12ga,10ga,8ga,4ga,28ga,20ga,16ga, and my 585HE and 700HE wildcat cases.....
The idea for the 12ga FH, and the first gun built for it,
was Rob Garnicks on the AR Forums. Then I and others joined in and set up a big variety
of guns for the case. First case a brass case 3.85" long, made from BMG brass expanded
out to take 12ga .729" dia slugs and a 12ga size rim added on. Also we get turned cases
from Rocky Mtn Cart of that length and shorter. Many guys used 3.5" cases
so that they could shoot 3.5" plastic also. Although our long chamber
will shoot any of the shorter cases.
Here are pictures, the first showing long brass 12ga FH case with
regular 12ga case. Other various 12ga FH guns are next,1887 with heavy barrel,
Nef Ultra heavy barrel with length added, Sav 210 bolt gun with heavy barrel,
Nef 8ga made by boring out heavy barrel 10ga,A FBW falling block in my 585HE belted case.
.And we also worked with 8ga,4ga, in falling blocks, 20ga,16ga in break actions, and
my wildcat 585HE,700HE in bolt actions, and more..Next picture is our big cartridges
from 2 bore on down, in order-2bore- 4ga- 8ga- 10ga- 12ga FH- 700HE--700H 3.25- 30-06..
The next picture is the 4bore falling block we built Our design. Our 4bore is 1 inch bore.
We also helped in getting the size built into the MRC PH action to fit our
cases like the 700H 3.25" shown in next picture.Next picture is an 8bore single
shot bolt gun a guy on another forum built from scratch..Last is a 8ga falling block
we built on same design as our 4bore falling block...Ed
