Can CCI #34 be used in bolt action as Magnum?

[rady]

I ask as they are listed as having a magnum mix. Looking to use in 300WM bolt action.

Why wouldn’t they?

Ive used standard large rifle primers in 300 WM loads and they worked just fine.

The 34’s have a thicker cup to mitigate the risk of slam fires in semi autos (specificly the M14). Other than that they are like any other primer.

Load and go.

Thanks nn. I have a chance to get some and I've never used these before in my 300WM and 338LM loads.

CCI does use the magnum mix in their #34 & #41 primers.

Yep, so if standard large rifle primers work, those with magnum mixes will also.

I use them, can't see a difference between #34 & 250s.

The only difference is the 34s have a harder cup for using in semi autos to help prevent slam fires. Otherwise they are the same.

A harder cup than the 200s, its the same as the 250s I believe. As well as less anvil protrusion and a bit different anvil angle to help in the resistance to slam fires Ive read.

That’s good news. I wonder if fed 210 will work on magnum rounds also. 300 prc or 300 norma. I have 8k of 210’s.

The 210M works well with the win mag and should also with the PRC however I’m not sure about the Norma as it may require a mag primer given the amt of powder.

The 34's work great in the bolt action. Thanks to all.

Have you tried them in your 338 lapua?

 

[John Glidewell]

Have you tried them in your 338 lapua?

I run them in my 338 Edge, they work very well. I have also used them in my 6.5 PRC, although I think the standard Federal match 210s work better in PRC.

No I have not. Used them in the Barrett MRAD with 6.5 Creedmore. This was just a quick test of the primers, so I really didn't pay a lot of attention to cbto, and other parameters. I guess I was excited to finally be able to get my hands on some primers.

I’m switching from 215m to 210m in my 338 edge.
Even with a big load Of N570 ES got a bit better.

The regular rifle primer is noticeably better than any magnum primer I tried in my 7 saum.

I’m soon to test that theory
