Found some “new” brass but the guys trimmed and sized it. Does that matter? I would think so but have a hard time thinking it needed to be

This.I run every piece of new brass through a die. And trim them as well. Sounds like he saved you some steps.
Have you received your Peterson brass in pretty good shape? I got some Peterson 300wm from UM a few months ago shipped to me in their cases and most of the necks were all out of round and needed to be resized.I had the same question over the summer.
Need to size virgin PREMIUM brass?
I just got some Alpha brass for 6.5creed and 7-08, as well as Lapua for 30-06. How many folks just load them up and shoot? I have some free time this weekend and would like to clear load development for these off my plate. 15% of me is considering not sizing them to save a big chunk of my...rokslide.com
I have since loaded Alpha, Lapua, and Peterson straight out of the box with no issues are load changes needed for 2nd firing and beyond.
Yes. Those and the alpha looked round. The Lapua had some less than round but still took a boattail bullet. I marked those and velocity was on par in load development with similar.Have you received your Peterson brass in pretty good shape?

Thanks. Maybe I just got a beat up batch. The ADG I received shortly after looked flawless, but I think they package them better. I'll likely just chamfer and load those.Yes.

That likely had nothing to do with the brass itself, you probably just have a tight chamber.In my rifle new ADG 30 Nosler brass needs to have the shoulder resized. This is checking the brass in my chamber, with a striped bolt. I don't know if it is just their 30 Nosler brass that needs sizing. It did not need a trim.
Curious why you mandrel and then FL resize after? Doesn't that just defeat purpose of the mandrel? Still trying to wrap my head around mandrel sizing and how that fits into someone's regimen.I like ADG. New-I like to run it through a mandrel die first, FL sizing die, then chamfer before loading. This process helps me keep uniform neck tension exactly where I want it.
The necks are typically are on the way-small side therefore requiring excessive force with the FL die- I have found it way easier to run them through the mandrel die and open them up before FL sizing.Curious why you mandrel and then FL resize after?

To the OP, I've had good luck chamfering and deburring new brass and letting it ride. However, you're not going to hurt anything to resize it first and it's likely a good idea. If nothing else, doing something to make sure the necks are uniform would be beneficial.
I don't know for sure. My gunsmith mentioned that the ADG 30 Nos. usually needed sizing when new, and to check it.That likely had nothing to do with the brass itself, you probably just have a tight chamber.
