12GA rifle From Hell--

[hubel458]

I found some 4bore plastic cases, 4 inches long, red
colored, looking like an oversize 12ga Activ case, They are all
plastic without a steel insert in the base like Activ cases
have. No markings. I understand they are Fiocchi.
They are the size for the 4bores that are about
.950 inch bore. They are suitable for shot loads of moderate
pressures. Guys loading them say they stretch out after
a few loads. And they use about 3 oz shot.
I will test them with a light buckshot loads
of nine 45cal buckshot, 140 grains each.
Total 1260gr, a little less than three ounces.
In picture are plastic cases with brass ones
and 3.3" 8ga.Ed

When I made the 16ga FH, shown earlier in this thread,
I had couple bmg cases that were partly worked down, and not
yet expanded to 16ga mouth size. With a rim on it bigger than the
base which was .770". Well, I've had guys ask if I would ever
have bottlenecked cartridge. This led me to a way to do one.
I made rim .770, left shoulder diameter, swage case sides straight,
and expanded neck for 585" size. Cut the case to 3.7" length, and
we have 585 Hubel Super Magnum, HSM. This will be my only
bottle necked wildcat. I can make the mag box on the MRC PH
long to feed case..Good for over 16,000 ft lbs, Regular 14,000 ft lbs.
Will that put trex in small letters.....Pictured with 505 Gibbs to which
it has nearly identical larger shape and good side taper for easy
extraction, with heavy loads.And I can make cases like I do with
my 700HE.Case hold 250gr ball powder under bullet.
It'll work in FBW Model L..ED
