Another shotgun/rifle experiment is 28ga FH.
Rocky MTN is making me some
3.25 in 28ga cases. They are good to 38k psi.
That will get 500-550 gr out at 2500 in
bolt action.A regular 28ga gun may get to
2000, depending on how heavy barrel is.Should
average 17-1800. Just lengthen chamber.
Get a NEF Ultra cut off leaving breech section
for monoblock and have 28ga rifled barrel
made and screwed or soldered in monoblock.
And being able to hold 38k to match brass,
That would get 2500 fps loads.Ed
