Some more gun info about what others around the world
are doing with big bores. First is a 4bore Tula pump
gun, made in Russia. A few guys in the US have them.
They are smoothbore and .938" bore. They used a short
3" long plastic case, and we helped some of the
owners get a run of brass cases by Rocky Mtn Cartridge.
Big Al, a poster on the AR Big Bore Forums owns one.
Our 4bore case is a full 1" bore 4.05" long.
Many early 4bores for shot were set up with .935-938"
Second is a bolt gun a guy in Europe did in 1" bore
using 20mm brass expanded, ending up for
headspacing, a small shoulder. It is full length like
ours, instead of shortened like other pipsqueak ones.
3rd is our big and small falling blocks, big one
the 4bore we made and other a FBW Model L in 585HE.
Both stocks need finishing in these pictures
and metal surfaces has to be finished...I'm not a
fancy, finish smith and to busy experimenting,
to get everything real fancy.
4th is a 20ga FH 3.5" chamber break action. It is a
CBC and we monoblocked in a heavy long 20ga barrel.
5th is a Mauser 12ga GEHA conversion, that had real
light barrel and cracked stock. We put the extra
Savage 12ga 24", rifled slug barrel we had in it, and
used the strong Savage plastic stock. Still has original
3" chamber and we test our slow powder 3" plastic loads.
Great load with full bore slug, is 600gr Dixie, using
90gr IMR4759, going 1800. This load was lab tested
and verified for speed and only runs plastic case, magnum
More info on cases, first is our cases where we put in a
bushing to use shotgun primers. Also some of the guys
shorten the cases for use in 3" and shorter chambers.
Magtech makes 2.5" 12ga drawn brass cases that guys
are reloading for use in short actions, like 1887 leverguns.
2nd is 8ga plastic cases we use, the left 2 are
REM and clear is WIN. These can be gotten at BPI
and Precision Reloading. We use roll crimp on
these for slugs and sabots.
1100gr at 2000 is a good load. 9 triple ought buckshot
is a good load. Totals 630gr for the 9, goes 2500
if you want hairy load.
3rd are 8 and 10 ga hard cast slugs with hollowbases, we use.
4th is some of our wildcat cartridge stuff, my 585HE cases,
die sets, and reamers. Dies are by CH4D, reamers by Manson.
5th is our 585HE in two break actions, a CBC and NEF.
Both set up by mono-blocking in 585 heavy barrels...Ed
