Does anybody have any experience in both of these? Or would you just go with the Peterson? I have a ton of fc 270 brass but I would like to get something better think these two really are the only options. Any advice would be great.
I’ve never used RWS brass or Peterson brass in a .270, but I’ve used Peterson in multiple other cartridges. I currently run it in .243 and my .284 and my brother uses it in his 6.5 Creedmoor and my Dad in his .308 Winchester. It has been great stuff and it holds up well. It’s typically heavier than other brands, so you might lose 50fps or so, but it lasts a long long time. It’s also very consistent and good stuff all around. The Peterson factory is only about an hour from me so I like to support them and they’re American owned and operated.
Have used and use RWS brass in my 375 H&H mag. It is slightly heavier than most brands but they are very consistent and are less than 3-4 grains difference between cases in each batch, often less than half of that. Additionally the case heads are the toughest I've worked with and primer pockets are tight still after seven reloads so far. FWIW. JM
I believe Peterson just started making 270 Win brass, so I doubt there is much end user experience. I requested to trial some samples via their website for them, but haven’t heard anything back yet. If they do send me some, I’ll post my feedback.
