I've shot alot of the 145gr from my 270wsm. Everything falls over dead. However, when recovering the projectiles, the cup and core are normally separated. The lead core is in very small parts, in a large wound channel.
I'm not a fan of have the cup and core separating, but the result in every case I've had is that the deer or tahr is in a heap just below the point the it was standing.
