Sounds like that was a hot load. Cant imagine they wouldnt last more than one loading. Starline is tough brass but usually gives less capacity. So loads safe in other brass may be over pressure. I would run Lapua.

I think that you have hit one of the major benefits of the 6 creed, you can have both. Use the srp for range use and shooting bug holes, and safe the lrp for hunting if you are nervous about it. I have never had a problem with ignition because I just started loading for 6 creed, but I’ll throw some rounds in the deep freeze and take them to the range and see if it works.
That’s a good point! I’ll hope the load is exactly the same for speed, poi, and drops. If so that would be a great option as well. That will give me 400pcs of useable Peterson brass. Should be enough for quite a while.

Guess I should have bought some CCI #450’s last week when I had the chance. Wasn’t sure what I’d ever use them for.... now I know!

FINALLY got some SRP Peterson brass ordered for my 6mm Creed a few days ago. As well as a K&M .062 flash hole deburring tool. Been shooting LRP Peterson brass and the brass is fantastic! Plus it comes with a reusable box which is very nice as well. Love that brass!

Been putting off the SRP for some time and just read on Petersons website last night about a couple negatives. Obviously it helps with low ES & SD but they talk about them not being as reliable as the LRP for hunters, especially in cold weather. It’s an aspect I never thought of or heard of until I had already ordered some of course.

The rifle is a hunting rifle which I also love to bring to the range and shoot bugholes with an occasional flyer (due to ES). I’d love to get my ES in single digits but would hate to sacrifice reliability. Has anyone experienced any negatives or ignition reliability issues shooting SRP’s?
This has been an on-off thing thing since SRP Creedmoor brass came to market, I think Lapua was the first. Guys were getting hangfires, 2 of culprits were not enough of slow powders, and it was happening in fast for the case powders, say Varget. After sometime it was attributed to magnum primers and small flash holes. Small flash holes were creating jet like burns, flame not opening up. So case fills, with either faster or slow for case powders were creating issues.

I don't think anyone really had issues with powder in the H4350 burn rate with SRP brass, magnum or reg small rifle primers. Didn't Peterson offer both small and large flash holes in SRP brass?

And comparing SRP creed brass to Lapua X 47 brass is comparing apples to toilet paper. Some guys predicted this would happen before any SRP creed brass hit the market. The case is larger, some said too much case capacity for SRP, in some extent, they were correct, but perfect storm scenarios.

The brass is going to work for you just fine, you just need to figure which powder-primer combo will get the job done for you in the extreme conditions you are predicting.
Good luck!

Great formation thank you. All I saw for Peterson brass in the SRP were small .060” flash holes.
I will be using H4350 and F205M, at least that was my plan. I can definitely do the freezer test as well to check freezing Temp scenarios.

All in all, I say you have the perfect combo. Not getting into internal ballistics, which of course I am not an expert, but getting the most efficient burn is paramount.
