Tell me about your obscure cartridge

[YoungGun]

I stumbled across another unknown cartridge (to me) yesterday- the 7 SAW, and after stumbling in to the Sherman Wildcat cartridges last year and reading about these various cartridges and their (alleged) performance, I'm genuinely curious about some of these obscure loads, wildcats, and everything in between. I'm not talking about cartridges that went out of style decades, or even a century, ago, or SAAMI spec'd ones that have ammo on the difficult end of the spectrum to find.

I want knowledge gaps filled.

Be my Tommy Lee.

This is one of several strange and unheard of cartridges. It is a Sako 7X33. Few have ever heard of it, fewer have even seen one. Here it is compared to a 223 Remington…

Is there a parent case you're using for this load? What's your typical bullet weight and MV?

Apparently my .280 Remington

I tried finding ammo for my wife's .280 Remington last year. Certainly not an easy one to find.

It ranks up there for things to find.

Most places I look have dropped that and .260 Remington in favor of stuff like the 6.5 CM and 7 PRC.

Winchester model 1873 original black powder cartridge.

I also have a .280 Remington. It got me into reloading since availability of factory ammo was spotty. It's great for reloading because .284 is super common. It took me about a year to develop a load that works well but I have enough supplies to duplicate the load when needed.

Is that 7mm Dakota in a custom rifle? I understand that it takes a bit larger bolt face, no?

There is no parent case, the brass and bullets are custom made. The brass is 30-30 brass that a guy turns down and puts the rim into the base of what is the case head of the 30-30. The same guy made those bullets by swaging the copper jacket and lead wire core. They weigh 87 grains.

It took me over a year to get it shooting because he didn’t have the rifle to check his dimensions when he made the brass and bullets. Once the brass had been made, we had to neck turn the brass so we could seat a bullet and get it to chamber in the gun

The bullets weren’t pushed clear through the sizing die after he made them, leaving a small rim of about .005 inches around the base of the bullet. I took a piece of flat steel and welded a handle on it so I could then place the bullet on a solid sheet of steel and then roll the rim flat to be able to seat the bullets.


When it was all done, it shot very well, as evidence of the dead gopher.

I just read something about being able to form 7x33 Sako from 350 Legend brass. I didn't check dimensions but it may be something to look into.

I had a couple cases that were made from 350 Legend cases, dimensionally it is about 4 thousandths too small. The 30-30 project did work. I found a guy that had a friend in England that owed him some money, so he traded for some Sako 7X33 brass and bullets.

The custom made stuff shoots as accurate as the factory stuff. I have enough ammo and components, I will never need more…
