404 Jeffrey Brass

Stuff is like gold right now. Good luck on your search.
 
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 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?
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.
 
Some of the best brass you can buy, made in the US. Well known is the precision rifle community.
 
While I haven’t tried this myself, this is from Big Bore Rifles & Cartidges Wolfe Publishing Co.

trperk1, I bought the Kimber Caprivi 375 back in an earlier post. You attached a target with an impressive three rounds touching 100 yards. I took the 2x10 VX5 off and put a VX6 HD Gen 2 1x6x24 Duplex Firedot on the rifle. It's definitely a shooter curious what loads you used for the group. Loving this rifle so fun to shoot. Africa 2026 Mozambique. Buff and PG. Any info appreciated.

Hello:
I’ll take the .375 Whitworth for $1,150 if the deal falls through.
Thanks .
