Here is pic of the finished breech block model
for the scaleup action.You can see hammer
and trigger mounted in the rear of the
block.Ed

Another experiment in shotgun/rifle realm is
28GA From Hell. 28ga is .550 bore and with 550Mag
barrels & bullets being made it is a natural. Have one
on bolt gun ready to chamber.Chamber still
will fire shorter cases..Ed

Tested AA2015- VV N130- Norma200- in plastic cases with small primers. They don't fire
dependably. Sqibs and misfires. Have
VV N110 ordered to test.Have had inquiries
about getting our cases shortened for strength
and they want to put in small primer.
They can be adapted with bushing. Ok but
must use 4759 or fast shotgun powders,
if they are used by themselves. Any slower powders, a fast shotgun starter powder
is needed. My testing shows RE-15 with 10gr
of Blue Dot starter is best of all we tested
in slower powders for shorter cases.Ed

Here is picture of the first falling block
model of aluminum, with a roughed out
stock to see how it looks. Action is a
rough model. It shoulders nice, and
lever is inlet into pistol grip,
so you can't get banged up
fingers with the big cartridges it is designed
for, like levers that stick down at the
guard.Ed

Now on this action you can use a older style
straight grip stock, as lever can easily
be straightened. Ed

Here is pic of action model with lever open
and the breech block down. Also the action
will have a slot in the rtop rear for a
top tang of whatever length you need.Ed

Info about the toggle link. It is up inside
the breech block, and quite short,and that
allows the overall height of the action to
be relatively compact, for the huge
cases we plan on using.But yet the top
part of the breechblock is solid for
great strength.Ed

Asked about using 900 gr saboted bullets in
3" plastic cases in regular barrels with
4759 or RL-15 and starter powder.
With bullets that heavy you'd have too
high of pressures with 4759
for plastic cases. Possibly could do
it with RL-15 and starter
powder in plastic, but only
in heavy barreled like NEF.

But the 600 gr Dixie is still the best for
most uses in plastic.

A NEF and brass RMC cases would handle 900 gr
Saboted bullet with RL-15 and starter powder. Start
at 80 gr Rl-15 and go up if cases don't expand to much to resize.Ed

Here is pic of a double that I will put
barrels in, monoblock style, using the breech
section for the monoblock. This one will be
for 28GA FH. May get another same size for
my 510HE. I will be able to run full pressures
with these.....I am trying to find a bigger,
heavier one to put 12GA FH in. I want
heavier one so as to run pressures like my
Savage as a minimum.Ed.

I was looking at an 8ga single on
GB, that looked heavy enough to put
a barrel in for 12ga or 700HE. They
wanted much more than it cost
new.It was a real heavy
Spanish single. If I found an extra,
or the 8ga Tonolini double, I might
leave it 8ga, as I could make a few
cases by reworking 20mm Suzy brass,
can be done without adding rim,which would
be super strong cases like our 12ga FH.Ed

Had question about locking RMC cases onto
lead slugs, as they don't crimp into the
grooves well as sharp bend works thick
mouth. First I resize tight and slightly bell
mouth.Insert slugs which take a little pressure.
Then I use a die with slightly more
taper and swage the mouth into slug, like
the fit you get with bottleneck cases.
Same deal works with our long cases made
from BMG brass.Ed

Preliminary testing with VV N-110 powder shows
it works with small primers like the 4759 powder,
in plastic cases. Perfect ignition on first
bunch of loads with 600gr slugs.Ed

Looking good, lots of great ideas brewing there it seems. The 28GAFH really looks like a neat program as well. I'm just waiting for you to get all the details worked out and start offering some plans. I'm a machinest and could easily build a gun from scratch, but don't have time for al the mockup and experimenting, trial and error so I'd have to have a proven set of plans to build off of.

Keep up the good work, you always get the gears in my head rolling when you post more progress.

George :)

More VV N-110 testing that we got done.
Starting loads are 60 gr min like 4759 for good
ignition,600gr slug. In 2 & 3/4" plastic full load is 75gr
with card and 1/4" cushion wad.In Nef 24" bbl 1700fps.
In 3" plastic 87gr, card and 3/8" wad, 1800 plus.
In RMC brass case. 100gr, card and 1/2 wad 1900 plus.
All running same safe pressures as 4759 lab tested.
So that is two powders that are slower than shotgun
powders, and much safer to work with for regular
primers, giving at least 20% more velocity. Ed

Testing soft buckhammer vs hard Dixie. Dixie 600 gr,
Buckhammer from factory hull 640gr with locked on wad,both
out of Savage at 2300. Dixie went through 2 -1/8" steel
sheets and on through two more 3 feet away.Buckhammer
went through first two with same round hole, but made
a bunch of dents and one cockeyed hole 3 ft away.Ed

Along with the two slower than shotgun powders, IMR 4759
and VV N110 that ignite reliably with shotgun primers,
that are easier to load for slugs, in heavy bbl can
get 20% plus more velocity, I've found another. It is
IMR 7383 $3 a lb surplus. Tested plastic 3" cases, perfect ignition with regular primers. 8 types of cases,600gr slug
starting load 100gr. Full load 140gr giving 1800 fps plus
in 24" bbl NEF.With loads halfway between start and full
didn't even have to resize to shoot again.Full load just has
a card wad under slug in 3" plastic.Wad just tight on
charge, as no extreme compression of powder needed.
Will do heavier slugs and
RMC brass cases. Ed

Tested 7383 with 730gr Dixie, 130gr gets 1650 plus fps
in NEF 24" bbl. Used 3" plastic cases. Same low expansion
as 7383 the 600gr loads and the 4759 lab tested loads.
Ignition perfect, no hesitation.Ed

Tested 800g slug with 7383 in plastic.Works good.
Have question about different cases and dies.
The RMC cases use a shotgun primer, thus they have
a real thick base. They are not a thin headed,
balloon headed case, and RMC makes sides thick
enough for regular 12ga wads.
But in a break action the 3" plastic cases
with our 4759, VV110, 7383 loads are close to RMC in
power. Can buy a hundred plastic for price of one RMC.
3.5" chamber 12ga with plastic is as good as RMC for 3"
And if I shot RMC in Savage to get more power,
which I could do as far as the firing process,
the expansion above the base, due to being a turned case
would make extraction stiff, causing extractor to
damage rim. A turned rim will not take what
a drawn one will. Rcbs set should do RMC easy.Ed

Finished test of 7383/870 slug in NEF.
Tested 870gr hardened slug with 118gr of
7383, got 1500 plus. Perfect ignition.
3" plastic case, regular primers.
Cases ejected easy, and has same base
expansion as the 600 gr slug/140gr 7383.
Will have these pressure/velocity tested
in few weeks.Ed
