AP for M1

[GeoDudeFlorida]

it covered all the 4895s including the recipe the Portuguese and Spanish were using (I forget the title designator they used) but in that general weight, the 147-155 weight class of projectiles

Maybe "CETME" (Centro de Estudios Técnicos de Materiales Especiales, or "Center for Technical Studies of Special Materials")? It was a 7.62x51mm but NOT a 7.62NATO cartridge.

Back in the days before the internet, shooting and handloading lore, rumor, and gossip had to be spread person-to-person. It was a slow and ineffective process. Too often, shooters would find a reliable source of information before the rumor and gossip could reach them. Thank goodness for the interwebs! Now rumor, gossip and innuendo can spread faster than Soviet propaganda. Back in those dark ages days I bought both an FR-7 and an FR-8 - not in one purchase but in the same year - and thanks to the wise council of some knowledgeable range roosters, went about shooting commercial .308Win and 7.62NATO in them. It wasn't until later I found out from a publication called "Shotgun News" that 7.62Spanish and 7.62NATO, while dimensionally compatible, were loaded to completely different pressures. I took to handloading a CETME-equivalent 7.62mm cartridge and me and my Spanish FR's had lots of good times together. Never loaded up AP for either one but did like to have fun shooting railroad ties with the Garands using AP. They make great target stands.

Have fun and be well.

You know Geo, I dunno ... I'm pretty sure the Port AP had that NATO + with the circle around it stamp on it. SAMCO used to sell it cheap, couple a hundred bucks for a case of blister packs, battle packs of maybe 300 ct per blister pack ??? ... it came out to something like 15 cents a round for the case of 1200 ct total I think it was ... this was back in the 80s, early early 90s before the AWB kicked-in. Green packs with red stencil were the AP loads. The yellow stencils were 7.62x51 147 ball ... but all of that stuff was loaded with 4895 of some sort. I cannot remember what the surplus prefix for the Port surplus was ... maybe it was just P4895 but that doesn't seem right in my memory.
