Hi
I just read that headline.  That's sort of a weird idea.  It seems like a lot of case for an early American "smallbore" "assault" weapon for the US Army.  Oddly enough, the Danish Krag was an 8×58mmR, bigger than the 30 caliber and the Swedish was in their "regular" 6.5mm caliber. 

Later

Just trying to help, I found this from an 'American handgunner' magazine doing an internet search.  https://americanhandgunner.com/handguns/revolvers/real-44-cowboy-loads/

Will continue looking for the magazines you listed on the internet and go back to my collection of GOTOW and also look.  I would have saved that article also.

Coffinmaker will probably tell you to get a Pietta.   

I had a gun  magazine, either Guns of the Old West or Shoot but cannot remember which one that had a good article on reloading these cartridges. I have not found the article. Can someone tell me which magazine so I can direct my attention to it to go through my collection?

Looking for a good used Uberti 1851 Colt Navy.

Sounds like good news all around. Gonna help the Missus with housecleaning in a bit, Nephew and his son are coming in tonight til Sunday, then we leave for Branson, MO for a few days for our anniversary. 41 years on the 23rd, wow. Amazing she hasn't shot me at some point. 81 here and heading for 93. And welcome to Summer.

Nicely done! And I love his ca'tridge belt!

Delmonico posted his new to him sweet Morrey Rifle
and his Great, Great Grandad, in the Tall Tales Coffee Board.
He is going to do an early Pre-war settler in Johnson County area of Nebraska based on the look...
Cool Idea

So, following in that footstep...
My Grandad LW Rice and his choice rifle circa early 1900's.

And my Browning 1895 in 30'06

Still here some better, last night took Coricidin nighttime cold & flu.
