There seems to be a shortage of standard pulled ball rounds for the 50BMG, I was wondering if anyone has tried to cast and powder coat bullets for their 50cal.

I looked through the first 20 pages of molds at midwayusa and didn't see anything associated with casting/sizing 50 cal bullets. It doesn't seem like a dumb idea to me so I'm sure someone has done this.

I didn't see anything about it in the 50 Cal Forum, since this is the Reloading Forum, I figured if anybody has done this they would post here.

They would only be for short range, low power loads just for cheap, blasting ammo.

There isn't any decent BMG compatible moulds.

I looked for a decent mold for my 510 Whisper and came up with about zilch.

Just have to know where to look. People shoot cast in 50bmg, I have no personal experience with either 50bmg or casting bullets that large. I have cast 600's for Beowulf subs.

NOE .512 diameter molds

I recall someone having a mold cut to mimic the 850grn amax

Also lots of designs available here

Accurate molds

I didn't know where to look, obviously.

That's exactly the info I needed to get started. Thank you, Jupiter7.

I like the NOE 513-580-SP 4 cavity plain based mold. Since they will be PC'ed I wouldn't think they would need GC's.

Another question: They'll probably come out of the mold at .513-.514, sized to .512 then PC'ed, they would be about .514 again. They would need to be sized again to .512?

For the most part I agree. BUT, with lots of alloying trial, heat treating trial and weight sorting, Moa or better is possible. Lots of work though. Only caliber I've gotten those results out of with PC/GC was 30-30, 1.1MOA at 2100fps.

I only size once. But that much of lead swaging may be better done in 2 stages with lube(case lube) on the PC.

ETA: I would seriously look to gas checks if trying to replicate full bore 50bmg, even with PC. If I was opting for plain base mold, I'd err on the heavy side of bullet weight to keep velocity down and retain energy.

Plinker loads are exactly what they would be for.

My OP says, short range, low power, cheap blasting ammo. Blasting 1 gallon milk jugs, watermelons, pumpkins and any other fruits and veggies that get in the way at 50- 200yrds. I have 2 farms (friends) where I've built shooting ranges, they like to shoot the gun but know how much ammo for it is, so they take 1 shot and say that's enough. I'd like them to be able to shoot it more and not feel guilty about wasting a lot of money. $2.50 to blast a milk jug into oblivion is a little high.

I've read a lot about making reduced power loads for rifles and will be doing so with 30-06, x54R and x39 cast bullets and PC. I have the time to experiment and develop a good load for the .50 so my friends and I can shoot a little more cheaply.
They would NOT be for long range, super accurate, competition work. I have other components for that.

Maybe I should just wait and see how the 30-06 goes then use that info for the fifty.

Thanks for the advice so far, keep it coming.

I've spent almost all day today reading that post.

I read the first 15 pages then skipped to the last and started going back. I figured the last posts would have up to date info, they do. Got a lot of info there.

According to what I've learned so far I think I'll get a GC mold, try a few without, if it doesn't work well then put GC's on them and try again. I think it'll work.

If I don't find anything specific to the 50 then I'll ask.

I would like to track down an AMAX clone, but stick with something in the 700-750 gn weight range.

Most all the moulds I could find were for black powder guns.  The only "BMG-ish" bullet I could find was way too heavy at 850+ gns.
