I've been looking for some new brass of about a year and can't find any that is under $4 per cartridge. I'm want to buy 100 - 300 if possible. Do any of you Reloaders have any for sale if so please PM me.
Why is it so hard to find this caliper?
Thanks

Isn’t that the case originally made from shortened 7mm Mauser?

Have you thought about necking some down from its parent case the 7x57?
I dont know if that brass is easier to find or cheaper

I have a 6mm Rem, also based on the 7mm Mauser, and needed brass. There is none available nor any parent brass available that I could find. I was able to find a 20 box of loaded 6mm Rem so went that route. Ammoseek.com has .257 Roberts ammo listed as available from various vendors running between $2 an $3 per round. The Hazmat fee and shipping will make it more expensive if you can't find it locally.

I come across Roberts brass and 6mm brass here and there. Owning a Roberts and knowing 3 guys that have 6mm’s I typically buy it. I just sold an extra bag a new Roberts brass to a guy looking on the trap shed. I’ll keep looking.

Yes it is but was hoping to wait it out and actually find 257 Roberts brass

Ok please let me know if you come across any more for sure.
Thanks

There is an auction house located near me that is selling all types of ammo reloading supplies etc They have just about everything you can think of at the weeky gun /fisihng outdoor related auctions held at least twice a month most of the armo would be in small amounts ut once in a while you could come across lots of 50 or more If you are interested in contact info PM me for th phone # and email info They have online biding and they ship items to the bidars Of course that would mean the price.

Baer auctioneers in Roger OH have lots of online ammo and reloading auction. I see 257 stuff there quite often. They ship but I don't know what they charge for shipping.

unprimed so no hazmat

Can't help with the Bob.......but as for the 6mm Rem, for past year or so, Graf's has had a big stack PPU brass on the shelf of their retail store, yet shows out of stock on the website. I may be up to 200 to 300 pieces by now. Enough a guy could finish burning out what is left of existing barrel, and another one after that.

For some reason, the industry has decided to sunset both once popular calibers in favor of chasing the latest fad. Would think with such a huge base of existing rifles in both calibers, somebody would go after that market. Starline comes to mind.

I have some used brass if anyone might be interested.

here are 92 empty cases and 19 primed cases from a variety of manufacturers.

I make 25 - 06 Brass from .270

6mm is popular out west.....you could put a feeler for some out that way....I got a couple hundred once fired RP brass very reasonable

if you have them you could sell them to him and he could resize 257

fired brass is no hazmat , just metal stampings when you USPS mail it

bought and sold brass online and not from a retailer several times.

Ammo Seek is showing several places with loaded 257 Roberts ammo. This is but one of them:

Five boxes gets you 100 rounds of loaded ammo to fire and same amount of brass to reload.

Bayou Brass & Ammo has 6mm remington brass on sale today 33 bucks for 50 new cases. you can run it through your sizing die to make 257 roberts
