Hi Guys
still looking for some 404 Jeffrey Brass
Mike

 

[Nevada Mike]

Stuff is like gold right now. Good luck on your search.

I just had to end up buying Hornady fully loaded ammo for the brass. I never could find it otherwise

I keep hoping that Norma will make a run but no such luck.

With the whole Bertram thing going sideways and Norma being unobtainable, it’s a real bummer. Does anyone know if Bertram is going to sell in the USA anymore?

I really don’t know if they will be available again, I would also like to try those 450gn woodleigh’s from Australia as well,

I made a post on the reloading forum about making 404J brass out of (375) Remington Ultra Mag brass. The 404J case was the parent case when the RUM line was designed. It's extremely easy to make...until we get a reliable source for proper 404J headstamp brass again.

I’m not sure but I think the case head is smaller on the ultra Mag

I use 375 RUM brass for making 458 African cases also

Case head size is not significantly different. I shoot it in a CRF bolt and a single shot. Still picks up the rim and ejects it properly.

Not the case head but the rim is slightly smaller in diameter. No problem in my mod70.

But not sure how available RUM- cases is?

The rim is only 4 thou smaller on the RUM - insignificant amount.

Good to know

ADG makes 375RUM and is readily available. I've found it as cheap as $117/50 in a hard case that can be used with loaded rounds.
