In the long barrel 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

Maybe it's because most of us are sitting back and reading the wonderful things Ed has posted, rather than adding useless comments like your own.

I cannot thank the guy enough for introducing me to the idea of shotgun actions for conversions. There are big power guns out there that can be unlocked with a little work. Guys are paying $2000-5000 for a new rifle trying to get the same thing: big energy. We are doing it for hundreds, and the rush of shooting it is still the same. I went out and bought a 210 just because of this very thread, and am currently converting it to a 20ga From Hell, down from a 12ga. It will be in a lighter, safari style rifle with iron sights. You can do many things with these guns and it's not all about having big energy all the time; it is about having big versatility.

big versitility? for what? why not just get a 500 Nitro?

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.
We will test 4227 with the same slug , and saboted slug
of some design. The 765 gr Fed slug is hollowbase for
smooth bores. Roll crimped with crimper in drill press.
Case expansion with 7383 very little(.006") like
the factory loads. 3.5" plastic cases.Ed

10GA FH info.Fed 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 another 150 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

Look real close at the bases of these
cases. What do you see. Comments...Ed

First two cases are ours we had made by putting rims on bmg
brass, The right ones a santa sent me and appear to be
drawn, high strength case that are same dimensions.
Are they worth rounding up, seeing as how the guy
who made our first bunch just retired. .......Ed

In 10GA NEF 110gr 4227 got 765gr slug
to 1800, ejected ok. If it was a really
heavy barrel it could do more.Using the
7383 surplus at 150 gr, don't even have
to resize to fire 3 times. The 28GA FH
done and testing in next couple weeks.Ed

Fired 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
