Has anyone tried resizing .303 British brass for the 30-40? It looks like it should work but I haven't tried yet.
I have a metric crap ton of once fired .303 brass but my stockpile of 30-40 is almost non existent. |

Works fine. A tad short, but no big deal.

'luvmy40': Is your .303 brass Boxer primed or Berdan? If you have military cases, they will most likely will be Berdan.
Berdan cases are reloadable, but, require different de-capping techniques. Correct size Berdan primers are also harder to obtain. It would also be good practice to anneal Case Necks before converting .303 British cases to .30-40 Krag. |

Thanks for the confirmation. |

Luck may be needed with that load. Here's IMR's pressure-tested data - .30-40 KRAG WIN. CASE; WIN. 8 1/2-120 PR REM. 180 GR. SPCL .308" DIA.; 25.5" BBL.; 3.00" C.O.L. Powder Charge Vel.

My old Sierra manual goes well above that, up to 42.4gr. I see their newer one does too. Hornady 3rd goes up to 40. 4320 was one of the first powders I worked with. I wound up kicking the bolt of my Madsen open because the data I used was developed in Winchester brass, but I was using GI brass. And, I didn't start low & work up, just picked a number a couple steps below max. Not enough numbers below, it turned out.
