RE: Remington Brass
The 300RUM brass for some reason is in real bad shape compared to all the other brass I get. I imagine its due to the size of it. I bet it takes twice the material to make 300RUM over say 7mm-08.
But I use to complain alot about it. Nothin you can do. Usually neck thickness varied from .012" to .018". Thats horrible. That caused bad runout. Some like the federal brass at D&R sports better. But you have to buy in bulk.
Pretty well, winchester and remington brass is junk these days in my opinion.
