There were some sketchy M1 garands awhile back may have been unsafe (I didn't order one so I have no firsthand knowledge) I too have had great dealings over many years with them
Marstar Swedish 8mm surplus ammo

There you go! I did not know that. As a kid we would throw a few 22 shells in a fire and duck and run..."as a kid" E.i. dumb.
But CF rounds were too precious for that nonsense. Too powerful as well, so I honestly did not know that.
In fact I shall bring that up at work tomorrow. Perhaps we can get enhanced value out of brass. It is discounted because it's dangerous. If we fire proof it, it should be a higher grade.
Thanks Zuke.
Call me sceptical. I haven't tried the BBQ, but when I've heated them with a torch (quickly or slowly) all that happened was they made a "weak fart noise" and were done. Even a loaded round (yes I did it and lived), was just a loud pop with the bullet moved a couple of feet, but the primer remained fully intact in both instances
I did this a few years ago in response to a deluge of "it's dangerous" concerns about fires and the mistaken belief that loaded ammo would explode in a mushroom cloud of red mist.
That explains my Profile Pic.
In loaded ammo, maybe the heat is igniting the powder before the primer?
A primer generates about 10,000 psi, so it just about has to fire our the back of the case.
I once wondered if it exceeded 500 fps, so I cooked one off and chonied it. less than 500 fps.
I think you might be right, that the powder ignited first and pushed out the bullet, followed by the primer going off in the now empty cartridge. Not an experiment I'm inclined to repeat, but interesting nonetheless.
How is it to shoot? I always thought the stories of broken collarbones was greatly exaggerated.
It's probably a bit more recoil than a .30-'06?
That's what I was thinking. It should have a 9.something twist like most 98 actions in 8mm.
I wonder what velocities they were pushing.
I think 2200 is about the top for a 220 grain according to the manuals I've looked at.
You can do better than 2200 fps in a mauser action with this 218 gr bullet. With the 8X63 Swede powder, I've used 46.0 grs for about 2150 fps, but slower powders do better than that.

Well, here's my dumabss mea culpa. Was annealing some cases and I forgot I had primed ten with 200s. When it went off it was most certainly more than a little pop. My ears are still ringing. The primer dented a case, blackened a few others, then tore through a stainless bowl. Found the anvil but the cup is MIA. Luckily I had my ballistic eyelids shut tight.
1.475 length at 218 grains.... not bad how far is the top of the cannelure from the tip of the bullet?
The German 7.9 SME (steel core) have a projectile length of 1.469 and 0.929 from tip to top of cannelure, and weighing in at 178 grains.
SMK (AP), SMK L'spur (APT), and PMK (API) also have the same external dimmentions and weigh 178, 154, 156 grains respectively.
Thanks for the research on loading for it. Nice to have an idea of where to start, and what it can do.
Just as a side note. I got as high as 2600 fps out of the 197.5 projectiles with the original powder, and the 178 is still in the works...... 2700 fps showed signs like some resistance to opening the bolt, but the primer looked fine. Need to crank it down due to less volume because of the longer projectile.... despite the lower weight. Anyways, enough of my rambling, the point is, I haven't seen load data in manuals over 2400 fps for a 200 grain 8x57.

So, the BBQ myth is confirmed. The primers do leave the casings.... it just might not be the safest thing to do.
The neighbours might think you have some MEAN popcorn in there.
It sure wasn't quiet. A LOT louder than popping off a chambered primer, as you'd expect I guess.
This primer was unstaked though, perhaps the results with staked primers would be different. I can't imagine that though, that sucker had enough force to punch through a metal bowl.
It was that barbque's last run. It was headed for scrap and I got curious
It was only 30 or so casing's the first time. More of a sound show then anything else. It got VERY loud!
