The 700gr US-S slug in smoothbore, at 2000
in a 3.5" brass case, got a 2.5" 3 shot group
at 50 yds. Great slugs they have come up with
for smoothbores.
Some of us talking about getting 10 ga rifled
barrels made, here is a picture of my 4.1" long
brass 10ga I made from 50cal Russian by putting
on a rim like the 12GA FH is built.Just a prototype,
third in picture. Later I'll get RMC to make some,
as it is much easier way. First in picture is
16GA FH 3.5" long, 2nd 12GA FH 3.85" long,
3rd 10GA FH 3.1" long, 4th 8GA FH 4.3" long.Ed
