+1 for old guns Canada, I've gotten some brass from him. Nice guy.
Rusty wood has 41lc redding dies for a press, although last I checked the price had climbed because they bought theirs during the tariff war, so they were a bit more, (which I get) however, I snagged mine from x-reload during a sale, I find them a little more expensive, but the deals are there during sales for sure, and sometimes they have hard to find stuff.
I've fairly recently started casting for 41lc with the hollow base that can expand to fill the barrel, it definitely takes more time than normal casting, but it is doable provided you can find the mold.
I plan on pan-lubing them as I normally powder coat my cast bullets, however I suspect it's not enough on these that intend to expand, likely cracking the powder coat.
If someone needed some cast bullets in small batches they could PM me (I'm in the maritimes) but could ship some to get ya started.
