Heavy Metal Bismuth Slugs - Quite impressive results
Added 2021-02-17 07:38:38 +0000 UTCEd cast some nice, heavy slugs for us using an Accurate mold and RotoMetal's bismuth alloy. Dimensions, particularly the outside diameter were perfect for rifling.
thanks everyone!!

Jeff: that's a bad link.

2021-02-18 22:39:18 +0000 UTCJeff: I looked it up at the RotoMetal website.... they have about 16+ different alloys of bismuth, so unless your friend can be a bit more specific on which alloy he used, I'm back at square one. Pure bismuth is on sale for $8.99/lb, but cast one pound ingots of the various alloys of bismuth are $17/lb. give or take making it way too expensive to buy 16 alloys and experiment. If you do find out what specific alloy he bought, please let us all know. Thanks!! A loyal Patreon subscriber....

2021-02-18 01:43:28 +0000 UTCIt would be nice to see how these behave when passing through drywall, or cinderblock. This might be a really good choice for home defense if it fragments and slows going through drywall. I would think you could get away with a lower velocity, as heavy as these are, and still get good stopping performance.
