Anybody here make & use cast bullets in their AR-15? I have a DPMS 16" carbine, not sure what the twist rate is, whatever's standard I reckon. Got lots of brass all prepped and ready to load, need bullets, considering casting my own.
Any suggestions for molds, bullet types, weights, etc.?
Coated lead is what I would use. Traditionally lubed lead will cause all sorts of issues in your gas system.
DPMS is or has been a 1:9 for some time.Quote:

Yes, please do! And I'd prefer to powdercoat them, I'm set up for it and do all my other cast bullets that way.Quote:

I use a Mihec 4 cavity 77 grain bullet mold. I have cast over 1000 of these and powdercoated many of them. Have not had the opportunity to shoot any yet though.

Hearing on the Cast Boolits forum that 1:12 is better, 1:9 is too fast. Gotta be gas checked too.
Someone straighten me out here, but it seems to me that with reloading plated and coated bullets for pistol people tend to recommend staying below super sonic speeds. I'll be interested to see how this works with .223 and other rifle speed projectiles.
Not supersonic, just below X velocity. Like 38spl or 357 staying below 12-1300fps? I have to check my log book and mfg specs.Quote:

Seems like a pain to get working right and a lot of work for .223, now with something like 300blk I would really look into shooting cast.
I've heard the term "gas check" before, but never really knew what it was. While doing a search to educate myself, I ran across this video and it seemed relevant to what Ron wants to do. Apparently you can make your own gas checks (even .223).

Yeaaaah, you can make your own GC's, but for the cost of the tooling and materials I could just buy a lot of 55gr. FMJBT's. A thousand Hornady gas checks don't cost much. Putting them on is a piece of cake with a Lee sizing die.Quote:

Sounds like you're giving up to me. Come'on, be a trail blazer. You can post up a detailed How-to and an AAR for everyone to enjoy. It'll be worth it just for the experience alone.
If I was going to tool up for .223, I'd be looking at casting a bullet and swaging 22lr brass as your jacket. It works (at least the ones I've played with were normal power loads and about 2moa.)
When you can buy a decent bullet for less then 8 cents it doesn't make sense spending the time and money (on GC) to cast them. Though it is neat.

This is my ultimate goal, I've got some samples guys have sent me of many different kinds of jacketed bullets made from spent .22lr, 9mm, .40S&W, and .223 brass. Pretty impressive!Quote:

Finally located my load data for Lead / cast 223 bullets.
I cast some bullets out of a Lee Bator mold, they dropped at 52 grains. Powder coated with ESC gun using powder by the pound powder. My little M & P with a 1 in 8 twist did not like them at all
Tip: Use different powder than Harbor Freight. Lot more uniform application.
Nothing wrong with Harbor Freight powder for pistol, but coating those little 22 caliber pills is tedious.
I also gas checked after coating.
Just my experience
You spray them or do the tumble in bag method?Quote:
