N568 33xc loads?

[JJ76904]

So I have searched pretty extensively on several forums, and can’t seem to find anything. Just wondering if anyone has tried it and how it went. Sorry if this has been covered and I just suck at searching on forums

I think N568 is a bit fast for the 33xc. I was using H50BMG when I had mine.

That’s kinda what I was thinking. Somewhat along the lines of you can use H1000 but it’s a little fast. It’s listed as a 338 lapua powder so I thought I’d ask, that and it’s available.

If you can find N570 is a better choice or H50BMG which Mid south shooters supply has instock $ 340 for an 8lb or $50 a pound

I have heard of guys using N565 also, I’m currently using N570 in my current barrel. I have H50 BMG for my spare barrel but have yet to work a load. H50 will give you better case fill than N570 but no issues getting low ES/SD w N570.

Kind of fast for 300s

Looks like AR 2218 (H50BMG) or RL50 are the way to go.

Looking at this data makes me think Peterson and Lapua brass are tough as nails. We have pushed up till light ejector marks w no heavy bolt lift than backed down and worked a load.

How many 33XC owners looking at those charts realizing their load probably makes 100k PSI. LOL.

Usual disclaimer applies: Quickload isn’t ground truth; it’s predictive data based on a number of assumptions, so only take it as simple ballpark predictions.

I appreciate the information

I think at 100k psi your past blowing primers. No one loads like that in my circle.
