I don't have alot of reloading experience nor do I have a chrono.
I loaded some .223 Rem. rounds useing 75gr. bullets pushed with 22gr. VihtaVuori n135 powder and fired them from a Wylde chambered AR. The CCI 400 primers were flattened just a little too much so I assume the charge was too hot. There was no coining on the headstamp.
I also so fired some 5.56 Guatamalan milsurp that did not flatten the primers very much at all but I could clearly see coining of the headstamp, I mean there where clear imprints of the extractor and ejector areas on the headstamp.
I'm not understanding why my handload would get a really flattened primer and no coining and why the Guat would get obvious HS coining and no flattening of the primer?
Any ideas?
Thanks Much
