Our friend Brian from the far north went to Africa with
his 24ga FH he did in
a NEF break action and got 3 nice buffs with it. Good
job.


Our 585HE, 700HE and the great 12ga FH are now in the new
COTW book
published in Oct, now out for sale,




We now have our target 375 HE cartridge, made by necking
down our 585 HE.
The others couldn't make enough 375s, so we started our
own. It has different
shoulder taper, length, neck length, improved over the
others...Got a bunch
guys doing it, most into the 2 mile shooting venues,
We're making cases,
testing, reamer prints at reamer guys, we are getting
guys going. The 2 mile
shoot last year really got the interest booming for 375
necked from our case,

Here's how, size and seat 375 HE, one simple die, a 1"
die, no huge dies needed
A die we can make with resize reamer from reamer guy, a
regular die body,then
pass on to the next guy, one reamer can make whole bunch
of dies for folks.

I do primer work separate, not in the press. SO First
with lock ring set, I size cases.

When coming back out of dies with case, we notice the
case still well centered,
held straight, when it is down as far as the length of
the 375 HE neck... IE
the sides and shoulder corner still supported tight.

So we put washer or another lock ring on, same thickness
as neck length,
below original lock ring, screw down tight tight in
press,

Dies had a 5/8 x 24 thread in top, had powder fill
bushing and other stuff same thread,
reamed out from bottom to set bullet height, with ram,
case,and bullet up,

After priming, loading in the powder charge, we
carefully start(boat tail makes it easy)
bullet in case by hand, slide up in die, into holder,
raise ram to to top, bullet seated
perfect. Die can have different thread in top as long as
big enough to hold seating
bushing of some kind , that can be made from many items.

These target bullets held in by strong neck tension, no
crimping needed, and notice
bullet point will get no marks or dents, fast, easy, no
380-500 buck special dies.
Bushing centering bullet on ogive is very accurate.

OVER 900 375HE cases piled behind presses getting done.
About 600 on another
bench nearly ready. Small batches in shelves.And we will
do more.

All 375 info, prints, specs, pictures, load data, etc, is
public domain, worldwide,
for any target, hunting, etc, use..Ed

Here is picture of one of 3 buffs our guy from Canada
got in

Africa with our 24ga FH he did on a NEF, in 2nd picture








Here is the neck die setup, with insert stems/plugs for
the top that

are set in .020" steps to make our 375 HEs shown behind

from our 585HE cases. 900 cases behind and 600 on

another bench, mostly done, and 600 started elsewhere,

We also made a hydraulic form die, 375 HE test gun,
starting with

lighter bullets, for example got 340 gr to 3700,

Will test up to 400gr We will find top speeds and powders
needed

to get that, and have info where to get powders. Reamer
prints are

at reamer guys, all prints and info is public domain...

Picture of fellows at Vestals Gunsmithing test firing
585 HE

they built for a guy. They got 750 gr to almost 2800 from

ultra short barrel, not a full load . A regular barrel
would be

over 2900, 14000 ft lbs with full load..





Picture of our 375 HE cases, with little 378 WEA on left.

Middle case is with 330 gr, right case is 400gr bullet.




Here is picture of out 375HE testgun, in heavy t-hole
stock.

So far 340 gr to 3700 and 360gr 3600.




Next 416 HE target case, these run through the hydro-die,

test gun done,will complete testing soon, to confirm
specs.

When specs set, info will be sent to reamer guys

Soon will have 408 HE with specs set up also, for guys,

Smaller case 416s and 408s can be reamed out for

our bigger case .Ed
