No idea.
Sounds like Nosler 300 RUM brass I tried years ago. Never did again.My experience is very limited. Only loaded it in a 300 RUM for a friend. Once fired Barnes head stamp factory wouldn't hold a primer after resizing. Could tap it on the bench and the primer would fall out. Barnes had seriously over loaded it from the start. Might explain the scrappy accuracy issues he was getting with a Remington custom shop 700.
This ammo is exactly where my fired brass came from, and also from 180g TTSX Barnes 300RUM ammo.I contacted Barnes and told them about the primer issue. Their reply was that someone had over loaded it. These was out of the box Barnes 165 grain TTX. That shot very bad. He also had some Remington once fired that I used until he found some Norma brass. I don't think the brass was that soft, but that Barnes was loading it to the hilt for speed. TTX hits pressure fast. I think it was a bad combination.
This is the exact brass that I am looking at to reform to 7STWBarnes sources brass from different companies. For example, we have Barnes headstamped 375 H&H on sale and that brass was made by norma in Sweden. They just headstamp it Barnes. This is pretty common.

I have not had a single problem with loose primer pockets, however, the 165g TTSX load was faster than the box as advertised and the 180g TTSX load was 200fps slower, just motoring along at 3030fps, not the 3250fps as said on the box.
In both cases, loads from Barnes were very accurate, both got under 1MoA with 10 shots, my usual test…
Cheers.
