** Update 13 November 2018 **
Another batch has been posted. 15,000 pieces of 99% Remington .223 headstamp.
** Update 04 August 2018 **
300 BLK is now posted in the EE
** Updated 27 July 2018 **
This will be the final update before everything goes into production. Optical HS sorter is a bust. So it will be of mixed HS, for now... All HS are ones that convert correctly to correct neck thickness. You will need to deburr and chamfer the or run an expander ball through the neck. This is because north of 2,000 pieces per hour anything I tried to do with neck tension started changing other dimensions significantly.
Trim length Average: 1.354" +/- 0.002"
Headspace Average (SAAMI): -0.003" +/- 0.002"
Average neck thickness (after deburr and chamfer): 0.0113"
Internal neck tension (after deburr and chamfer): 0.302"
The end user should deburr and chamfer the brass prior to loading, or you could use a Lyman M-die and crimp it
It has been a slow process, I know. However commercial loaders are my bread and butter, and they have been consuming all of my .223 / 5.56mm equipment time. I now have a bit of a break where I can get these small projects sorted out.
** Updated April 22**
The first pre-production batch is going out to testers on Monday. Once it is verified, then I will be releasing brass en-masse.
I ran into two issues that will increase the price slightly from where I had hoped. But really, we are talking like $5 per 1,000 increase at this point. Current pricing is looking like:
$90 per 500
$165 per 1,000
$160 per 1,000 for large quantities
One - I can't run as fast as I had planned. I was running around 2,500 pieces per hour, but shattered a carbide insert and destroyed a boring bar - so the actual cost of that plus the speed reduction to 1,500 parts per hour for the feed rate to reduce the thickness of the swarving to allow it to break apart for vacuum extraction.
Two - Optical sorter for brass headstamp is slower than advertised. Actually operates at 1/2 of speed advertised to achieve the level of precision I demand. I aim for 99% headstamp accuracy, and if I run it any faster, then that accuracy starts to drop off quickly.
I haven't run a complete statistical analysis yet on the production setup, however, these are the pertinent details:
OAL Length 1.360" +/-0.002" (98%)
Headspace SAAMI (-)0.003 +/- 0.001"
Neck Thickness Range 0.0105 - 0.0115"
I will be spooling up production on converting brass from .223/5.56mm to 300 Blackout. I am hoping to have the optical sorter functioning. We shall see. I haven't set a price point as yet, it should be significantly more economical then what is available currently. I am waiting to see production rate and how quickly I burn up end mills. I usually get 150,000 pieces of .223 per end mill, they are expensive, so I do have to factor that in.
Will be available in 500's / 1,000's
Brass will be:
Camdex Processed
Formed
Trimmed to length
Cleaned
