223 / 5.56 Brass

RifleDude said:
FWIW, I did a test a long time ago where I compared identical .223 loads using brass sorted by headstamp and weight (+_ 0.25gr) vs brass unsorted by weight and headstamps. The surprising thing was that the unsorted lot gave me the smallest groups. The test gun was an AR15 BTW. Maybe in bolt action guns it would be different. Being a bit anal though, I still sort by headstamp and weight but the test results made me wonder if it's really necessary for hunting type rifles.

Why would you accuracy test and not velocity test?

The brass does not contribute to group size, it contributes to velocity... Sure variations in velocity can cause group distribution, but so can wind and the shooters skill.

The purest measure between cases will appear on the chronograph... Assuming you have an accurate scale... Not some POS beam scale or even 1 decimal place digital scale. Otherwise you are just measuring the collective inaccuracy of your entire reloading and shooting ineptitude,

LOL, you don't know much about accuracy.

Velocity variation is only interesting to ELR shooters, for most other forms of accurate shooting, velocity is one of the least interesting parameters.

Benchrest shooters, who shoot the smallest groups on the planet, don't measure accuracy and they throw powder through a manual measure because velocity variation is not important to them.

If the case does not produce accuracy, then why do the most accurate shooters in the world spend so much time on brass prep and maintenance?

You are aware that cases like the 6PPC and 6BR were specifically designed for accuracy. They have numerous features that increase accuracy over other rifle cartridges.

RifleDude tested for accuracy because for a target shooter, that is the only important factor.
 
Thanks guys. I had a couple offers from police ranges for free once-fired brass in support of our new shooter program.

That's awesome. Police brass will probably be all of the same headstamp. Also, the look on those junior shooters is priceless. A few years ago, I had one of my grandsons participate at one of your junior shooting clinics. He still talks about it and gets a huge smile on his face as well. He was shooting one of my long range AR15s at the time and could believe how well he did at 300y. He was especially proud when he hit his playing card 8 out of 10 shots. It's still in his possession. Keep up the good work!!

a newbie trying to teach Ganderite about reloading is quite funny,the man has more experience than pretty much anybody on here,LOL

you are the one that was telling Ganderite he should have been trimming every few reloads<..i think Ganderite knows a lot more than a newbie,

You go back and read my post. Its #22. The name of the person I quote and was replying to is right at the top of the post. Then you can come back and apologize.
 
"He should have been trimming every few loadings to prevent excess OAL problems."

I think you meant to say that I COULD have trimmed.

Yes, I could have. But when making 4,000 rounds at each reloading my options a bit different than making a just a few hundred for myself.

I size and reload the whole batch each time and toss it all when it starts to g out of spec.

Nope, I meant you should have. Six firings is running the risk of excess length cases and we all know the potential serious problem that can cause.

Doing the kind of volume you were, it doesn't surprise me you wouldn't want to hand trim, but there are power trim options. I've just finished up converting a Dillon 1050 to run as a dedicated case prep machine, with the Dillon power trimmer. It works great and really pumps the brass through. While trimming every loading is certainly overkill, the machine is set up to do it.
 
That's really going to depend on what they were trimmed to in the first place.
If I trimmed and chamfered back to 2.240 or shorter the first time, I doubt one would have case length growth such that chambering became a problem at around 2.260 or greater.

Ganderite: Have you ever considered running a loading clinic for these youths that ran concurrently with the shooting? They get hands on learning what goes into making their ammunition and you get from them a bit of 'sweat equity' on their shooting program.

What makes you think I am a reloading newbie?

I've been reloading for 38 years. I load more than a dozen different cartridges and I have 8 or 9 presses, including three Dillons. I couldn't even hazard a guess as to how many rounds I have loaded but it would run well into the hundreds of thousands.

Pretty sure I am qualified to comment. You, I'm not so sure about.
