casting for the 300wtf/whisper/aac/fireball

[buckshotbarlow]

Ok, who here is casting for this thing on the subsonic level? Anyone running boolits through theirs with a can? I have 2 wtf's, 1 in an ar, and the other in a remmy700...

I'm looking at getting this mold:

I hate spending the coin the 220SMK's when i can damn near get the same performance through a boolit. So i checked out Magma, they have exactly jack shit for 30cal rounds, lyman has this one...

Anyone else out there doing cast for subsonics???

Just finished casting, powder coating and sizing a few this weekend. Hopefully will get some time to go test 'em out loaded this weekend.

I have been wanting to do this for a long time. Everyone says that it is unadvisable to cast for the blackout, but it is the only way that I can afford to shoot it as much as I want to. And everything considered, it is the best rifle I can think of to cast for. I have had pretty good luck with the 208 Grain amax, but that too is now fabricated from unobtanium and I can just sit here and look at my 300 blk boat paddle.

clocker, those look awesome. I would love to see some range tests with those. I want to see range test information for all of your powder coated bullets. The only thing that still concerns me is the possible deposit of powder coat on the inside of the barrel. Do you have access to a borescope that could take pictures? That way you could see before, after and after a good cleaning just to make sure that there are no problems. What mold did you use for those?

[clocker]

Unfortunately I don't have access to a borescope, but a lot of people report clean barrels and an ability to increase velocity without leading. There is a concern with lubed cast lead in suppressed applications due to fouling, but the PC should solve that. Here's another pic of a few different boolits that I am getting ready. I was fortunate enough to pick up a bunch of molds before folks made a run on that market.

All Lee molds PC with some Eastwood powder and baked at 400 for 20 min. Then sized with Lee push through or Star dies.
TL430-240-SWC
452-255-RF
452-228-1R
TL356-124-2R
TL358-148-WC
TL309-230-5R

Do you powder coat then size them or under size and then powder coat?

[Danimal]

Also what alloy do you use for the TL309-230-5R ?

[clocker]

PC first and then size. The PC is robust enough to stay attached to the lead and makes it so that you don't have to lubricate in order to size. I am just using reclaimed range lead for now. Got some WW and linotype for later if needed.

[Danimal]

I have a whole bunch of reclaimed range lead that I have to clean up and make some ingots one of these days. I am really curious to see how it all turns out and how they hold up. I looked around for the TL309-230-5R and looks like that one is going to be a ways out for me. I think that I am going to go ahead and backorder one from Midway but they are not going to be around until October.

[Danimal]

What size do you resize to? I see Lee push through for .308 and .309, and I am thinking of going in that direction.

[clocker]

309 would usually be better since the general rule of thumb is to go .001 over bore diameter. I sized these with a .308 though since it was on the shelf at the time. We'll see if it makes much of a difference.
