In the short term, yes. And if there's microfractures, they won't heal themselves. As for the eroded areas in the lower grooves region, I'm thinking it's gas cutting. It was quite shiny just after having been recovered. A bullet trap that would damage the bullet less would be helpful. Could drag the revolver down to the "crick" on the hunting property and procede to get wet!

Cast a bunch of bullets, but fought with the process for well over an hour. Couldn't get good crisp edges! Even with the melt nearing 800°F. Finally just cast a mess until the pot ran dry, threw in the sprues, reject bullets and some overflow back in the pot and started again. Oddly, the bullets came out much better, even at much lower temperatures! The two melts will be kept separate. Would like the mould to drop bullets ~0.002" larger, but have yet to try "beagling" the blocks.
