Here is picture of 24ga FH in the Mossberg bolt gun. On a
Mossy 390 frame, .585" heavy barrel, same as 24ga size.
Chamber is set up 3" with shotgun style forcing cone,
so it can use 2.5" plastic cases and 2.5" Magtech brass
cases with slugs or shot and for 3" cases we use 577NE
3" brass. Really make a hairy 24ga using the 440gr to
540 gr Minie bullets at 21-2400. If you take 540 Minie bullet
mould and leave out base pin you'd have a 650gr that
would do. All these bullets and slugs as well as jacketed and
turned 577/585 bullets work in 24ga as well as my 585HE.
And the smaller Minies work in our 12ga sabots. I keep
saying 58cal is where it is at, and there are more bullet and
slug choices in the .585 size, easy to find, than any other
caliber over 458. And Minies are like 40 cents each and
cheaper if you cast your own.

Here is picture .585" barrels from McGowen, with other barrels.
Most of the McGowens profiled and some straight blanks.
Others we have are the slow twist and smooth blanks...
In back some of the cases and die sets.

Here is picture of an Enfield and a BBK in Hogue recoil
reducing stocks. These stocks are the rubber coated ones with
the easy to grip, nice pistol grip.Has McGowen 26 inch barrels,
1 to 20 twist, barrels are heavy profile and taper
to .980 inch at the muzzle. Setting up 4 more on Enfields
through the winter. Ed
