That US-S pointed slug with discarding petals,
and locked on base, shown above is called the
Swift 12. And correction on the weight, it is 320 gr.
And they plan on testing and maybe supplying 3.5"
versions, planning on getting around 2500 fps with
shotgun powders. I know in our 3.85" case in the long
barrel Savage, I could get over 3000 with big amounts
of our slower powders we load with.
Bought some tubing caps And here is picture
of those copper tubing caps, you can make bullet
jackets out of, and fill with lead. In picture you see
a rough one I formed with punch, and with a die they be
perfectly formed. And with right die they could be
formed with round nose with edge step for perfect roll
crimping in plastic. And on the right see big caps that
would do 4 bore.There are caps between the two sizes
that would do 8ga...Ed

Here is picture some folks wanted of our
big cases with smaller 30-06 for comparison.
In picture, 1st my 2ga, 4ga, 8ga, 10ga, 12ga,
my 700HE long case, my 700H 3.25", and 06.
2nd picture is short 2 5/8" brass cases we
are checking loads in, to see how much speed
can be gotten.You can easily see the length of
short full bore lead slug, compared to the
saboted ones, allowing more powder in the short
slug load for more speed..
Now this doesn't mean saboted are no good, or
that I don't like these saboted types. Great for
smooth bores, the US-S with locked on base, are
the best there is, I think, for big game.Just
got to use longer cases. I always felt, that going
longer cases is worth the effort where practical ED

Ed, can you tell me some more about your .700 HE cartridge?
If I understand things right, it's basically the 12gaFH, except you swaged some of the taper out of the case to provide a belt to set headspace.
Does this cartridge use the same .72 caliber bullet as the 12gaFH? The only spec I found says the neck diameter is .740, which looks about right.
If you can point me to a page somewhere where you explain things in detail, I'd appreciate it!
My state has no caliber restrictions, and the last gun show I went to had new, unfired BMG brass for $2 each... since I have to build the chambering and sizing reamers from scratch anyway, it would be cheaper and simpler to go with the .700 than the FH, as long as I don't have to eat the barrel I already bought...

My 700 use a .700" caliber bullet, not the .729 12ga size.
I do have reamers for my 700HE 3.25". And I have dies.
My short 700HE 3.25", mouth is .740.
the long 700HE, mouth is .735"- 3.87" long.
I make 700 cases by machining and swaging, ending with a
belted case, where on 700HE the belt is .795" - base .775"-mouth .735".
If you set up 12ga FH with 3.5" chamber, and then you can use regular
available 12ga 3.5" reamers, and get brass 3.5" cases that fit same
chamber from RMC.And chambers will take plastic 3.5" also.
Maybe the most versatle way to do it as long as you
already have 12ga barrel. What gun is barrel for..Ed

Some 28ga FH info and ideas.
Brenneke now has 28ga slugs, with good speed,
decent smooth bore accuracy. About 260 grain
slugs. SAme style as their 12ga ones with locked
on base.Work in 28ga NEFs of course and
28ga O/Us.Some real good 28ga O/Us out there.
28ga is a .550 Inch bore.
But now Rossi has out, a revolving 28ga shotgun
with about a 19 inch barrel. Should work ok with
those slugs. You could also get RMC 28ga brass cases
about 2 3/4" long, maybe 3", depending on chamber,
a shorter version of our 28GA FH 3.25" case.
Maybe I get one in the future, and put on a longer
heavier 585 cal barrel and set it up for my
585 Short HE. Have a switch barrel 28ga/585.
Neat gun.Called Circuit Judge....Ed

Some have a need for supply of full bore 12ga hard alloy
slugs about 620-650gr. So a couple guys are opening up
their Lee Key Slug molds to full bore .729" It will still
have the partly hollow base and key. I will do the
short brass cases with the first ones I get, to get loads
developed. The slugs are about same length as
the 730 gr Dixies.They have blunt round nose and
can be roll crimped in plastic cases ok. Load of 90gr
of IMR4759 in the short brass or 3" plastic cases
will get 1800 plus in 24" barrels.
I'll Have pictures later to post.
Also here is picture of my 585HE in a Khan
shotgun action. Operates as a straight bolt,
straight pull action for now. Barrel is heavy,
30" long, the butt is weighted. thick pads,
it fits nice, looks great. Ed
