Thread: New 223

It could/should work well trimming the original neck to touch the lands. Or you may need to use a smaller button like .25 cal to keep the base, on the bolt face. Cream of wheat is just filler but I do not use it anymore. Patch works fine/easier.
You could walk around the rd to see that fella. He may be already out walking the neighbourhood in the nuddy! He is weird like that! But he has certainly been a sounding board for me over the years as far as reloading and smithing goes. He is bound to have samples of powder you may need as well.

Very cool. Will follow with interest.

What he said.

And you know the difference between a bullet and a pill

Do you reckon he should try some of those pills you just got for me Chris? I reckon the 75 grain pills would be what he is after.

Touche fella!!! I should friggin know better by now

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.

Yeah, the quality if the case is not the same as say lapua match brass, it is military brass(suspected design life of one firing).

Out of the 80 cases ive fromed, only 4 have failed. I know I'm not going to get 15 fires from them. At the beginning of the project, this was the my main concren. But if I can get 5-6 fire from a case, I'm happy.

Having four split on the first fire is ok to me and is all part of learning the pros and cons of the whole thing. From the case ive fired more than one, some up to 4 times have not failed, so in good shape overall.

Spoke to Red today and he never followed through with this option.

Anyway, having 54gr load doing nearly 3800fps for now is good.

Tonight i'm back load 60gr Partitions, 63 Serria SP and the short 70gr Speer SP all with 2206H.

Will update again last tonight with results.

Right, good results with the 60gr Partitions doing 3550fps in front of 31gr of 2206H, this is a bit of a hot load and cases look good and the primers starting to flatten on the edges.



30gr of 2206H gave 3440fps



Managed to stabilse the short 70gr Speer SP with 30gr of 2206H (not sure of speed as I had some Crony issues last night). These bullets have the same BC as a 200mm concrete block and not sure how these will continue to fly further out.



I haven't run the 63gr Serria SP yet, or the 62gr Barnes (this is a long bullet). I'll look at the 70gr Speer a little more as a shorter range deer bullet. But looking in pretty good shape here.

Summary to date:

53gr Vmax -31gr of BM2 gives just on 3700fps - groups really well
55gr Blitzking - 31gr of 2206H doing 3620 - tight enough(i'll find the target and post it on here)
60gr Partition - 31gr of 2206H doing 3550fps - very tight group to date, about an half inch
63gr Serria SP - work in progress(haven't fired them yet)
68gr Hornady HPBT - 31gr of 2208 doing 3260fps (target looks like a shotgun blast)
70gr Speer SP - 30gr of 2206H - not sure of speed but will look at this again too - group less than an inch
70gr Branes TTSX - 31gr of 2208 doing "fast enough" - shotgun effect again

Still to do:
say a 40gr bullet going really, really fast.

Anyway, doing some range work tomorrow morning and then looking for a deer on Sunday with the 60gr Partition!!!
