I always looked at APCR as one big solid shot. Never thought that if it consisted of multiple materials that that would mean its not solid shot. I know that the Tungsten core would break off and keep on penetrating when the metal jacket gets stopped. That didn't make me think of it as an sabo like thing.
kerponaut: it does matter. APCR are essentially sub-caliber rounds with non-discarding sabot, therefore they have tungsten core. AP, APC, APBC and APCBC, on the other side, are truly full-caliber solid bullets with different caps, and are usually just made of hard steel
APCR, APBC, APCBC, APC, ACDC does it really matter in the end they are all Armour Piercing rounds.
I also checked that Full caliber uranium penetrator rounds have been used in 20-30mm autocannons
@kerponaut then its not AP, but APCR
@Beatless123 Many if not most full caliber AP shells used tungsten cores.
can you please put mine in? id:2583774
Full caliber AP shells never used tungsten or depleted uranium. Only APDS shells use it. Howitzers are typical for low shell velocity so they use mostly HE, HESH or HEAT.
