[QUOTE="MagnumManiac, post: 2198132, member: 10755"] Interesting fact regarding primers...the term ‘flattened primers’ did not mean the same as it does today. Prior to the 70’s, factory primers were concave, not flat with a radius like they are today. This reference of flattened primers meant that if you experiences a completely flattened primer, you were pushing the pressure limits of the brass. I still have boxes of Kynoch 416 Rigby rounds that are loaded with concave primers, albeit larger than we use today, and dozens of old 222 ammo with the same rounded primers. Funny how quickly such things fade from memory. These rounds I have were produced when very little reloading components would have been available. Cheers. [/QUOTE]
