Just to back up a bit; if you liked your 180 Hot Core load and are just looking for a replacement, you could probably just get a pile of 180 Interlocks and live happily ever after. Its not like Hot-cores are bonded or anything other than ordinary.
Not that there’s much wrong ordinary, most of the time.![]()
Hot cores are bonded. They pour the bullets instead of swaging and as a result get a solder bond. Part of the appeal is they're the same price as a cup and core, but they apparently just like their military contracts and don't do a lot on the commercial market.
