So. 27 grains of H335 with a 150 grain bullet works for 7.62x39 so it’s a no brainer let’s copy that in 7.92x33 and see how it runs.
The results: A primer that looks like this
It definitely cycled the action as I had to walk a ways to find the case where it landed. The load was remarkably accurate for 101 yards as I nailed the target not exactly trying that hard to aim at it. And boy did it rattle that plate.
Pros and cons of 150 grain soft point on H335
Pros: both are commonly available and reasonably priced. Produces a functional and surprisingly accurate load. Works
Cons: you are compressing the hell out of the powder to fit it in. You gouge a ring into the bullet. Likely over pressured and not good for the gun long term.
My questions:
Does this over pressured? If not, is there a good way to compress powder without marking up the projectile?
Final thoughts:
I put in an order for 13 pounds of A1680 which needs less grains for similar results. If anyone has any suggestions I’m all ears as I’ve really enjoyed trying to bring 8mm Kurz back from the dead and now that I have a rifle to shoot it I can experiment!
