CCI no. 34 primers

[Brian in Montana]

An acquaintance recently gave me 300 of these. Not sure what to do with them. Probably the closest thing to 7.62mm that I load is .308win. Any reason I couldn't use these in .308? How do they compare to CCI 200s?

They are designed to be harder to ignite so rifles with floating firing pins don't inadvertently set them off.

They would probably work just fine, but I wouldn't use them on a once in a lifetime hunt or anything like that.

I have used them in an AR10 in 22 250 And a Ruger american. They always went bang when I wanted never went bang when I didn't want.
You can probably work up a load for anything needing a large rifle primer with them.

They work just fine in most rifles. They are just a little tougher so you don't have slam fires in certain rifles. As long as your firing pin spring is decent, they will go bang.
If you have a Colt Light Rifle with original firing pin spring, they most likely won't work.

They are magnum so reduce your load by a grain or two and work back up. I have not had any problems with them other than lever guns that have reduced spring tension on the hammer.
