Sorry in advance, can't find the answer with search. I'm almost ready to buy my reloading equipment. My question is, does the brass get trimmed before resizing or after? I've heard about both different orders but nothing definitive. I will be reloading for 300 Blackout and 308. Also, are certain die makers better for different calibers? Example - would say Brand X dies are better for 308 than Brand Z but Brand Z better for 300 than Brand X? Thanks in advance, hope I make sense.
