300 Blackout AR15

What about a stable stripper clip type extrusion, and a table saw, or radial arm?
You could run through three, or four feet at a time.

Converting 223 brass is easy, I went to princess auto and bought a 6 inch chop saw and cut off 700 pieces at the neck. Then deburred them on my RCBS case prep center. Then run them through the sizing die. Then trim to length and inner/outer chamfer case neck. Time consuming but worth the effort and you don't need to do it all at once. I did a couple hundred just to get shooting then finished off the rest a hundred at a time.

Even without a suppressor the 208gr subsonics are quite quiet. They really hit the gongs hard to which is fun.

I'm really excited to get a non restricted barrel in 300BLK built for my ACR.

I've also bought factory loads for $16/box so it's not overly pricey to shoot if you don't reload.

christ....my JRC 9mm carbine with 147gr ammo with a FAKE suppressor (the Ebay ones) was quiet enough to comfortably shoot with no ear protection. I Can imagine that with a suppressor like our US friends have, it would be all bolt noise.

You my friend must be the smartest man alive, you are now my hero ;)
I never thought of stripper clips. I have lots of those and they would let me do 3-5 at a time and also keep my fingers further from the disk.
Next batch I'll give it a try.

Remington UMC white/green box 115gr FMJ was $16/box at P&D in Edmonton last year when I bought 6 boxes of them. I've been using handloads since then so don't know if the price is still the same.
As an added bonus my PWS Mk109 9.75 inch barrel shoots them into just a little over an inch at 100yds :D

Easier than the chop saw method. If you have access to a lathe, a buddies lathe, a buddies buddy that works with a lathe. Chuck the brass in the jaws (gentle now....), and I used an end mill to trim down to approx .020" above case length, run em through the sizing die, and then my Lyman case trimmer to finish them off. And of course I used a neck chamfering tool. Takes about 1min each to finish per brass.

I do the same thing - chuck them in the Taig, cut, size and trim to OAL.
 
If you remove your depriming pin assembly
lube up your brass and reform the brass (with out cutting yet)
then cut to length (rough in chop saw - band saw etc)
then trim, to trim length
then clean all the chips off
then deprime, your brass will be ready to load unless you have to fix primer pockets
 
Damn you Suputin! Did some reading up last night on 300BLK etc and also converting .223 cases and damn, lot easier than I expected. Ok, I'm a convert! I'm gonna start building a 300BLK for next spring! Gonna buy a set of dies and make up some brass this winter. :)

 
I use a chop saw, 2 brass at a time (hold on tight). Then to a Hornady Pro 7 (5 position) #1- small base 223 + depriming #2-300BLK full size (no depriming or expander assembly in die) #3- Modified 308 Dillon trim die and the RT1200( needed to mod the press a bit to lock the trimmer die in place,no room left on the die for a lock ring) #4- is empty #5- another 300BLK full length sizer with expander assembly but no depriming pin. Then I debur inside and out, and then military crimp removal and back into the tumbler.
 
Because most of the prime suspects are in this thread and due to the conversation we had regarding the 300 BLK and hunting, here is the prime source of info for this round and hunting with it. Check out the specific Hunting forum as there are loads of guys in the US taking hogs and deer with subsonics as well as more conventional supersonics.

Cool, thank you.
 
I love my .300blk rifles. Got both a Core15 16" AR and the little H&R Handi rifle And I'm gonna be a shameless plug and say that my 16" AR is for sale right now on the EE
