hubel458,

Thanks, I'll contact Rich and see if he's interested in testing some. I'd like to see how fast they can be driven without any leading. I would also like someone to test my .620 LFN in 900 grains. It should be ready next month. Maybe a 600 OK owner or Wayne at AHR.

I tested your 585 hardened 750 gr in my 585HE
and got 2500 with no leading, Used card wad under
slug, as that helps cut leading like a gas check..In fact
I think card wad is better than gas checks.My 585 will
put them out at 3-400 fps more than that.

Tested 35" smooth barrel in 1887. Got couple
1 oz foster slugs over 2400, with 110gr
of 4227. 3" plastic case, regular primers.
This is a heavy barrel for that type of load,
don't do this in your 12ga skinny barrels.
The 28GA FH cases on the way.Chambering
bolt gun for it now..Ed

In the 87 long smooth barrel got
1 oz Brenneke to 2400 with 110gr
of 4227, You could use 4759 and
VV110 also at lesser amounts.
Barrel is cylinder bore size.
Brenneke slugs need no wads as the
locked on wad works good.Ed
And going heavier in 87 got 600 grain
Dixie over 2000, got a Buckhammer slug
I took out of factory load over 1900.
Buckhammer and locked on wad is 630
gr. Tested in 3" plastic cases.

The firing pin on the 87 didn't protude out
like I like them to as it comes from factory,
so I removed .015 from the hammer stop.
It fires big and small primers perfect.Ed

10GA FH..a NEF 10ga, medium to heavy wt smooth barrel.
28" long, gun weighted to 14lbs. Factory FED 765gr loads
are 1300 fps. 200 gr of first powder tested is 7383 surplus
and the regular shotgun primers got 765 gr to 1600,
for 4300 ft lbs. Case won't hold anymore 7383.
Federal factory hollowbase slug is .025" smaller than
10ga bore. I bumped it up to the .775" size, by expanding
hollow base. With 7383 that gave 1750 fps.Fast starting
shotgun powders expand base better than much slower 7383.
The Federal factory load has 120gr of wads/seals about 1.4"
long. Better to replace with much more slower powder,
getting better velocity, still at low shotgun pressures.Ed
We will test 4227 with the same slug , and saboted slug
of some design. We roll crimped with crimper in drill press.
Case expansion with 7383 very little(.006") like
the factory loads. 3.5" plastic.Used one .050 wad.Ed

Got 28GA FH done and testing.
Loads- 28GA FH-- Cases extract easy.--It is
in bolt action Enfield. With 550gr jkt slug,
full load 150 gr of WC-860, got 1900 fps.
This will be slowest load and powder.
In picture is 3.25" brass 28ga cases, regular
28ga plastic case, jkt slugs, a 458Win
for comparison.Regular cases work also.Ed

28ga cases are made by Rocky Mtn Cartridge,
Barrel is rifled with 4 grooves, 1-22 twist.
You could do one on Savage 210.Another
shotgun bolt action that would handle it
with little work, heavy barrel, is the
395-495-595-695 bolt action Mossberg.
Just to show that 28GA FH isn't puny, here is
picture of it next to a 505 Gibbs.Ed

Here is picture and info on Royal
Arms' site for hopped up 12ga loads,
used in little cannons for bomb work.
Anyone got any of these fired that I could inspect to see how they are built.ED

I like the Savage 210 so I'm putting
a 700 barrel on one and chambering for
my 700H 3.25 case. Working on it now.
It is a straight belted case, .700 cal.
Should get the same energy levels as
the 12GA From Hell case in same action.
In pic is 700H case in the action.
There is guy building a 600 Nitro
in 210 also. Ed

28GA FH research. Guy on forums suggested using 54cal
rifled barrels for 28ga as they are easy to get. I looked into
it and did some testing. It is ok as long as you keep bullet
about 400gr as most 54cal barrels are not super alloy.
You got to use the thick heavy ones also, being stronger.
And everyone with 28ga wants slugs and there is no slug loads
from factory, and to reload the heavier bullets we shouldn't use
these barrels or regular 28ga barrels with 600-700 gr slugs.
But there are couple dozen 54cal bullets out there
stocked all over the gunstore shelves, in weights from 300 to
450 gr. There are heavier but for 28GA FH on deer 400gr is
great. I tested the 405 gr copper plated Powerbelt brand, with
velocities from 2300 to 2800 plus fps. That's 6500 ft lbs.
The 54cal slugs load tight in the RMC 3.25" 28ga case fine by
sizing top a little tighter. Bullet obturates to fit .550 bore
as bullet is hitting target straight. A lot of 54cal barrels
go from 530 to 560. 54cal slugs range from .534 to .560"
There are different sizes of 28ga barrels and chokes,
so some where there is lighter 54cal slug that fits..
And with light slugs the pressure limits with the MRC brass
match top muzzle loading pressures, so these barrels will work.
And great thing is the 54cal barrel guys ain't allergic
to making long barrels. I've shot one MRC case 15 times and
still going strong...Ed
