I can only think of 2, that actually fill a gap in my view of the world:

6.5mm/06

585HE in 3 1/4" or better yet 3" version

Calibers I think you'll be able to sell with no major factory existing headstamped brass:

6.5/06
.280 AI
.358 STA
.416 Taylor (Quality Cartridge carries this)

You might also be able to pick off some business with the NE's that right now only Bertram produces:

.450 3.25" NE
.450 #2 NE

my vote is 338/06 but I bet a 358-WSSM would sell in indiana

....are my favorites.

1) 35 Whelen
2) 338-06
3) 416 Taylor
4) 358 STA
5) 470 Mbogo

Only the first 2 have anything to do with "usefulness." The others just count for me b/c frankly I had trouble thinking of another three I thought all that useful, but these sure are cool. Maybe I'm confusing utility with necessity.

I would like to see the 45-120 Nitro Express, along the lines espoused by jeffeosso, standardized. I also like the .416 Taylor offered. A single source for these two would be a plus.

the 45/120 nitro has taken root, and it is growing .. trust that its going to be the "next" hot loaded 19th century round!

Gee,
Ya mean I was a trend starter with my Trail Guns Armory 45-70 re-bore back in the early 90's

Most folks thought I was nuts

1.) 323 Hollis
2.) 338/06
3.) 9.3/338
4.) 416 Taylor
5.) ????

Seriously?

1. 400/.395 Nitro Express 3" Aboriginal ... aka 10.03x75R

2. .395 Ruger Max

3. .398 Lapua Magnum

4. .395 Tatanka

5. 500 Mbogo-Mobogo

I see quite a few picked the .338-06, and it's "already" a factory cartridge with factory ammo available...

The 22 K-Hornet, and any cartridge derived from, or inspired by the case head dimension of, the .222, 7.92x57, .375 H&H, or the .404 Jeffery.
