is it death of WSM and RUM?

[BruntBronze]

I'm really concerned that my non-creedmoor rifles will be safe queens with no good source of brass.

Does ADG and others produce these calibers? Yes, but i dont think they will continue without a wide marketbase.

I used WSM for 6.5 WSM and RUM for my 7mm wildcat.

I read how remington is being split up as part of their bankruptcy.

is my view point skewed?

ADG makes 300 rum brass and 300 WSM Winchester brass was quite available not long ago.
I see both staying alive especially 300 WSM as it’s still popular for hunting and some target uses.
300 RUM seems to be getting some traction again as well for ELR use.

I do not think brass in less popular chamberings will be come non existent. May be shorter runs and fewer made by producers to try to match supply-demand. Several of them are still popular, but 100 brass for 300 RUM hunting rig will last most hunter their entire life. Had mine for about 16 years. Bought 100 brass with the rifle, Never hit the 200 rounds fired mark before i sold the rifle about a month a go. With new chambings poping up and being sold now days, I figure the amount of brass per chambering will be more spread out overall.
