Peter these were to the best of my knowledge origional Kynoch.However having said that I have had a good look at the remaining samples from the lot that I fired and still believe that to be true. I do have a five pack of Kynoch that is different in that the primer is silver instead of brass and it has vissibly less crimp by .oo2. There is the purple primer pocket sealer but like the solid bullet egsample it is not on the primer while the soft has none. If cordite was the propellant would it be stick lengths as all these samples have a loose powder sound when shaken. I am in the cartridge collecters club and bought them from various members when I was building the rifle to get correct magazine length and feeding sorted out. I have tried to post pictures without success. Can email to you if you PM me an adress.
