Shot 12 double ought buckshot in 1887.
That's 624 grains worth. Used short
2.45 inch case that feeds from magazine.
Used fast ball powder, getting about
1500 fps. Further testing on 600 gr
hardened slug got 1700.That is in short
20 in barrel. Comparing this short case
with the 3.07 inch case I use in NEF there
is an inch difference in length of powder
column so it takes faster powder with
10k more pressure in 87 to get same
velocities as in NEF. But the 1887 handles it fine.
It takes as much pressure as my Savage
in its present form.Ed

I got Rocky Mtn turned 12ga cases, and am
developing loads. They are 2 7/8 inches
long are for use in NEF and shortened
in 1887. These cases have shotgun
primers. Now these cases with shotgun primers and the two cases of ours we put small primers in don't fire the slow rifle powder loads
reliably,like cases with bmg primers.
Our testing is with 600 hardened Dixie slugs.
So I have and am testing slow shotgun powder and fast rifle.I tested 5 shotgun powders and
the primers fires then ok but the quick peak pressure when loads increased to get velocity
wanted in NEF caused too much case expansion just ahead of the base.Cases ejected ok but
that expansion and resizing will ruin cases
in a couple shots.These cases have a real thick base, and are machined to glass smooth finish.Nice cases.
I now testing AA1680 Ball and it looks good.
Have got loads up to 105 gr with 2 wads in
the Rocky Mtn case, and only .002 expansion
of case ahead of base. Will chrono next and
expect it to get velocity we want in NEF.
Nice thing about this testing is that same loads will work in shortened 87 case by just
using less wad column.Ed[/align]

Thanks, nice to be compared to 700NE
It willkeep up with 700 NE in my Savage with slugs/bullets
and in Rob's gun outdo 700NE. Case is longer than NE.
And we are testing NEF and 1887 as a source
of info for 12ga shooters wanting little less than
what my savage and Rob' gun will do.Ed

We tested RE-7 powder and got good results with
very little cases expansion. Got 600gr t0 1700
in 87 and 1850 in NEF. Come to conclusion that to
get the potential from the 87 and NEF that plastic cases
would work like the turned case .And we tested plastic.
Our testing has proved it with RE-7 loads........
And soon will test other powders.
Plastic feeds better in 87 levergun, as well as
all brands of pump and autoloading shotguns.
In testing plastic cases in NEF and 87 I get
good case life with RE-7 loads. In 87 a Rem case
fired 5 times and it looks good. In NEf a Federal case
fired 6 times and looks good. Of course you can fire them
once or twice and throw away at 3-5 cents each.
I got long heavy barrel ordered for 87 levergun,
and then we will be able to put zip to the slugs.Ed

Testing the heatreated slugs for speed I put spitzer point on Dixie
slug getting wt down to 500 gr. In Savage, full length case
got it to 3800 fps with 350 gr of ball powder blend.They
don't lead at all, and seems the faster they go the
cleaner barrel is with less fowling.Ed

Nothing to patent really about cartridge.Just a long shotgun case made from brass
in a barrel and action taking higher pressures. Differerent companies have brass cases and long cases. When they went from regular
2 & 3/4 cases to 3 inch cases I never heard of a patent.Same going
from 3 to 3 1/2..Only thing maybe to patent would be how we put
rim on the bmg case, but cases could be used for our case, a 700NE,
a rimmed 50 cal, big rimmed 458, rimmed 416,
etc.Ed.

Got the NEF chambered for long case. And remember it
has beefed up hammer for bmg primers used in our case.
Got 2500 fps with 600 gr slug, cases eject out real easy,
8300 ft lbs from an NEF with 24 inch barrel.If you set up
NEF to use regular primers adapted to our case or
have Rocky Mtn make a long case you can do it without
a lot of work on the hammer and springs. Just use a
flake shotgun powder as a starter powder above the
primer, which how 700 NE and others are loaded.
Use 10 gr of flake and cut regular load 40 gr and
work up if pressures allow.Ed.[/align]

I got the hammer on 87 beefed up to fire big primers.
Still testing plastic and turned cases in 87.
We are testing small primers with 10gr starter powder(Blue
Dot) and RE-7 and 15.Plastic cases max is 90gr RE-7 with
10 gr starter, turned brass case 110gr RE-7 10 gr starter.
WE had to go to starter powder as we was getting
delayed ignition and squib loads.
Testing the cases,plastic and brass with small
primers and starter powder ... A big find. IE, we can't do
this for reliable ignition if the cases
are ballon head, whether plastic or brass.The cases must have the area between side and
the primer at least .200 thick.One reason is
strength. And some plastic I have measured is
only about .060 thick there and the protrusion
in the center for primer is .140 above that
thickness.. So 10 gr of starter powder is
in a groove so to speak and not on top of primer!!! That isn't good. I cut the cases
off at the brass base, poured in 10 gr
of flake powder and saw how it laid
in the case. Nice thing is that a most brands of cases are thick enough, like Win AAs.
So far RE-15 and Blue Dot starter looks
very good, and easy on cases.Velocity as good as RE-7.Will keep testing and I ran out of
RE-12 and the shops have no more, So
it will be RE-15 which I think turning
out best, or RE-7 in smaller
amounts.Ed.[/align]
