After reading about the .338 SPECTRE round for the AR-15, I got thinking about more punch for the 9mm AR. I remember reading about the Wildey semi-auto pistol from the 80's. It was chambered in a longer 9mm and 45ACP version called WINCHESTER MAGNUM. The 45 Winchester Magnum is in Hornady 7th Edition, but nothing on the 9mm round. This might work in a gas operated 9mm setup. I also remember reading about making a Hot 38 Super out of .223 Rem Brass, just another thought for a new round.

#2 from the left, 9mm Win Mag with 250 gr Hawk .354" bullet ... Randall at Ar15barrels.com made similar rounds from .223 cases ... essentially he made .357 Mag Rimless ...

I may have a box of 9mm Win Mag cases - I just can't find them right now. Don't even know why I have them - if I still have them. Might have thought about trimming to 9 Bergmann/Largo for a Destroyer carbine.

The Win 9X23 and the old 9X25 Mauser Export broomhandle(?) & subgun round might also be rounds to consider.

Borchardt. The 9 x 25 was the initial design. Deemed too powerful (?) it was necked to 30 cal, to make 30 Mauser and copied in USSR to 30 Tokarev. Still considered too much and a little long, it was shortened to 30 Luger. That was then opened back up to 9mm, to make 9mm Luger ....

Borchardt was the first working pistol cartrdge, before that was still revolvers loaded one cylinder at a time ...

My dream for quite some time was an AR in 45 Win. Mag. I now can up the ante a little more for a hot .45 shooting pistol bullets by getting the .450 Bushmaster.

If you want a hot 9mm, consider the 9mm Dillon, a 10mm auto case necked to 9mm.

All of these have issues with magazines and perhaps being too hot for a blow back action, although continuing to add weight to the bolt and the buffer can help take care of the latter.
