Thread: New 223

Awesome project, looks cool. I like the sound of 223 SDDR, or 223 LA (long as). I'd name it that so I could then post the project on all the American forums in hope that it got popular and then had a ridiculous name.

Watching sith interest to see how it turns out.

That would suit it well imo

I was talking to Robbie about this/his 5.56 Maximus about 2.25 years ago, glad to see something happening with it

Redbang has a dummie.round he made for him a few years ago of this round. Was just waiting for the right rifle to bring it to life

Was this the Thompson I mentioned at the start? Has Red got it?

Been out tonight with 2208 and 68-70gr bullets. I've heard a heap of people talk about bullet stability in general, but never seen the results when it doesn't work out......until now.

Bullets going sideways over foot in either direction of the target! pushed the 68gr BTHP at 3260fps at the muzzle, but at the target was a different story. After the first to shots, I walked to the target to try and fine the hit, it wasn't there. Fired some more and managed to see the bullet strikes in the dirt behind the target, but these were randomly placed.

Managed to see a couple hit the cardboard(a foot away), these went through sideways. So, lighter bullet for the 1:12



After I got over the fact that the much wanted heavier bullets isn't going to fly for this barrel, I continued to fire form more case (with 53gr vmax bullets and 26gr of BM2). 15 shot group below, split 2 cases in the process.

I now have 4 fires the first lot of cases I formed and I know I can 3700fps with the 53-55gr bullets in front of 31-32gr of BM2. Will try 2206H anyway and maybe some 60-65gr bullets too.

I would be a bit concerned with the cases splitting, seems like a flaw in the brass.

I have had a few once fired 50 cases like that, I got them like that.
