I ordered this one Christmas Eve, or thereabouts. I"m not sure if it's one of Michael's designs or a copy, as I've never seen one of his in 158 grain. I"m a big fan of Michael's moulds/designs as they have WORKED for me in every caliber I've tried. They seem to make load development easy. SO, here goes.....

I've been testing and messing around for several years, looking for the perfect ONE
almost perfect 357 bullet I can use for
almost everything, which is easy to cast a lot of, easy to lube/size (if even necessary) and had high hopes for the LEE 358-158 TL SWC. It's worked great in some things and just OK in others. Primary consideration is excellent accuracy in a carbine, which is where it was pretty ho-hum in SEVERAL carbines. LEE's 358-158 RFN shot better in everything and is a good bullet for most things, but it didn't wow me in terms of accuracy in either revolver OR carbine. It was OK, but not amazing. I've yet to stumble onto a "one ragged hole at fifty yards" design for my carbine.
I cast for a friend as well as my brother, and we all have revolvers and carbines. I have my fingers crossed that this will be that ONE which does most everything for all three of us.
I've had such good luck with all of my RDO moulds (.225", 311", .313", 358", .432") that I was actually ready to give up on the 158 grain weight and start looking for a copy of the 175
@CWLONGSHOT found. I ran across this one at Arsenal Molds and I have been VERY happy with the one other mould I've purchased from them, so here goes nothin'. I'm going to try it.
I went for 4C aluminum/NO GC.
@CWLONGSHOT , if you want to try this one once I get it and get it going, let me know. I can send you some to mess with.
By the way, Arsenal makes the mould you order. I've seen a lot of designs I like at NOE, and I LOVE their moulds, but I've only ONCE ever been abl to get one of their moulds and I did have to compromise and take what was in stock. Shame. They have nice designs. My covid-extended wait for the Arsenla mould is 3-4 weeks, which isn't bad. First one came in I think about a week.
