With help of a local vet, I’ve been experimenting with X-raying cartridges. The results so far have been much better than either of us expected. It’s also raised some interesting questions. We x-rayed a number of Spanish CETME rounds expecting to be able to see the two piece core which was clearly visible (see below). However, a second cartridge showed a homogeneous core. This cartidge had a more conventional bullet shape, weighed 19.4g (compared to the other CETME rounds that weighed 19-19.6g) and had a core that by x-ray appeared less dense than the lead core of the standard CETME rounds (this difference doesn’t show up on the posted image). The weight range for Spanish lead cored NATO rounds is 23.6-24.1g (based on my collection) suggesting that the core of the round in question is not lead. I’be been unable to find a cartridge fitting this description in any of the Spanish cartridge references. Any help would be appriciated as I don’t have a spare to section.
Top Representative CETME cartridge hs P 7.6 62 Br cs and pr Gm bullet
Bottom CETME?? hs P 7.6 60 Br cs and pr GM bullet
Thanks to Dr C for his time and use of his x-ray equipment
