Question about CCI #34 Large rifle primers

[notaglockfanboy]

I owned a SKS up until my wife found a rifle she wanted, so me being PWCP I traded the SKS for her .243. So now I have 300 CCI #34 primers and am wondering if they can be used in a standard bolt gun. I use CCI #200 primers to load with anyway, so are the #34 primers just harder to prevent slam fires and use the same charge to ignite the powder, or are they hotter?? I am not lacking primers to reload with, I just hate to see them go to waste and would like to see them put to use.

Sure you can. They are considered magnum primers. Work up as always particularly if you're close to max loads.

I use the cci #34 primers in my M1 loads. I've never tried them for other cartridges even though they should work. Its just me...the M1 gets special treatment!

Can you tell any difference in the loads compared to standard primers??

The CCI #34 primers are Magnum strength primers so if you treat them like a CCI-250 primer you will have no problems. BTW, the cup is no harder than a magnum primer, the compound is just slightly less sensitive. The fact they are magnum strength primers comes right off the CCI site.

So are you saying all magnum primers cups are harder than standard primers cups??

I'm no expert but I think the magnum cups are slightly thicker than standard cups but the NATO class primer cups are no thicker than magnum primer cups. (thicker, not harder)

I think the numbers are .020" and .025" but I'm working of memory and I'm getting old!

Thanks for the info, I did not know that. I do know they specifically sell the #34 primers for semi autos to prevent slam fires, but did not know that about magnum primers. Not sure I will use them in my .308, but my father in law loads for his 300win mag with magnum primers, so I may give them to him. They will last him a long time, because he only shoots a few shots a year when confirming his zero and while in Colorado chasing elk.
