adi brass

[jeebo]

For a beginner like myself, it's good enough to learn reloading on and until I find a problem with it, I won't be in a hurry to change brands.

Ditto, I think you have to be chasing waaaaay more accuracy than is relevant for a beginner (me too really) for it to really matter, as long as you buy something quality.

I started my 223 reloading with 80 ADI cases.
I have now shot 500 rounds through my rifle with this brass.
I have never had any issues and are full length resizing every time.
The brass still looks like new. I sonic clean them after about every third load.
It's cheap and good value.

For what it is worth from a newbie to this game ..................... I just bought the following:

100 x.223 ADI unprimed cases with the following stats
Weight of Case
std dev 0.271
Median 90.800
Mean 90.801
Min 90.1
Max 91.4
spread 1.3
Most frequent 90.7
#number within +- .5 grn of mean 90
neck brass thickness (sample only) .0120 to .0135
unsized start length (sample only) 1.755

100 X .223 Lapua Match Cases with following stats

0.427 std dev
95.300 Median
95.330 Mean
94.300 Min
96.500 Max
2.200 spread
95.100 Most frequent
63.000 #number within +- .5 grn of mean
.0130 to .0140 neck brass thickness (sample only)
1.750 unsized start length (sample only)


on this sample ADI is a good deal for all but serious target rifle...but even then the proof will be in the durability of the cases .

Note :
1.no cases have been turned and on sample measurements Lapua is both more consistent in neck wall thickness ( slightly) and thicker in dimension, leaving perhaps (?) more scope to turn necks to a lower thickness and higher consistency.

2. Both samples bought from same retailer on same day.

thoughts ?

Well, first... Welcome to the Forum.

Second... "Thoughts?"

What are you using to take your measurements with, neck thickness & weight.. ?

More scope to turn necks.. well that depends on what they are being used for and the chamber dimensions.

Buying from the same retailer on the same day doesn't mean much. ADI cases are good quality at a very reasonable price . Lapua are Match Grade cases and come in specific Lot numbers of which can vary. Same as Powder.

Not too sure what the point is here as it's like comparing chalk with cheese.

Does case weight have any value at all?
It's a waste of effort to weigh the brass until after you have trimmed them all to the same length at least, fixing primer pocket depth and flash hole diameter would also be good before weighing. If the lightest case also happens to be the longest one what does that tell you?
It's probably more accurate to weigh them after they've been fire-formed to the chamber as well so they're all the same dimensions.
But weighing them doesn't tell you anything about their volume, and that's what really matters.

[Apollo]

All other things being equal, then weighing cases does give you a pretty good idea of what is most important...case internal volume. Measuring case volume is a very slow and time consuming task that also needs to be done correctly and not with just plain old water. Either way the internals of the cases need to be spotless, not full of old burnt powder residue. Fire forming first I believe has very little to no advantage other than coating the inside with crap, more to the point and like most case prep is to FLS every case first, then trim necks and you have a series of cases that are the same datum point measurement on the shoulder and the same neck length so overall they are pretty close. Firing them might flow a little brass around into other spots but it's still there so doesn't change anything really.

This sort of stuff is all about precision target shooters that are willing to take every task to the extreme to gain just that tiny, tiny fraction of improvement in accuracy and/or consistancy. Certainly not for the average Joe and probably not with ADI Cases that really are not up to the quality standard required.

It's all pretty crazy, just depends on how crazy one wants to be...

Me, I'm pretty stupid crazy but a couple of friends I reload for don't think so when they saw the improvement of accuracy and started winning competitions. I mean really, who weighs powder loads down to individual granules of powder and checks them. Haven't gone crazy enough to count every one of them yet...

I bought a bag of 100 of these when I picked up my .223 and have reloaded them 6 times now with no failures at all. That's good enough for me.

I purchased 100 Brass stamped OSA from my local gun shop. OSA and ADI I'm told are the same thing.
From new this brass has only been Neck Sized never FLS.
35 are in waiting for their 3rd firing.
Using Hornady Digital Calipers & the Hornady Case Head Gauge
- All 35 loaded loads had a Headspace measuring 1.454"
- As for the other 65 cases that have already fired their 3rd loads.
- 31x measured a headspace of 1.456"
- 27x measured a headspace of 1.457"
- 7x measured a headspace of 1.458"
- Mind you I have never trimmed this brass and those 65 cases had variation in case length of 1.751" to 1.755"
- 2 cases measured 1.751" & 1 case measured 1.1755".
- The remaining 62 case lengths measured between 1.752" to 1.754".
When I Purchased these 100 cases the weight variation in the batch was 1 grain between the lightest and heaviest brass casing.
For the $38 spent on these 100 cases I consider them excellent bang for my money.
You can draw your own conclusions on the OSA (ADI) brand brass.

G'day all. This is my virgin post so please be gentle with me. A few admissions first. I am one of those picky handloaders who does everything to prepare brass except H2O case capacity. Hey, at my age, (three score years and then some) some things are just too picky! Been a rifleman since I was around that tall....
Recently managed to (finally) buy a Savage 12 Long Range Varmint rifle with right hand bolt, left hand port single shot in .223 and so here starts my experience with that calibre. (My armoury travels from 17 Ackley Hornet to 300Win Mag).
I was given 100+ unfired ADI brass by a friend of mine headstamped A D I 00 F1. I would say it had been a few years since manufacture. It had uniform annealing marks on each cartridge.
I also purchased 100 Remington brass from my local gunshop in rural/regional area.
OBSERVATIONS: This is a no-nonsense quality brass that I would compare any day of the week with my favoured Lapua.
PREPARATION:
Tumbled in corn cob media.
Full length resized with two (pain in the butt) stuck cases.
Trimmed to length, or tried the first ten that were spot on to 1.750 +/- 0.0005 (I did them all anyway - did I say picky)
Neck turned to 0.011 again, after 10 they were entirely uniform (again I did them all - beautiful brass to work with)
Using RCBS prep station deburred the flash hole. A microscopic burr was evident before deburring but quickly removed.
Primer pocket chamfer
Primer pocket sized - no material removed
All pockets perfectly uniformed
Debur and chamfer necks as per normal
PRIMER:
Remington No.71/2 Small Rifle Bench Rest Primers seated perfectly just below base.
LOADING:
26.5g ADI AR2206 (compressed) fills to half neck but presented no problems with 50g HDY V-MAX and 52g SIERRA MatchKing HPBT seated touching lands in both.
FIRING:
Easy bolt close and eject, no pressure signs and back to the reloading bench.

This brass returned 'unchanged' aside form more defined shoulder (as expected from first firing).

CONCLUSION: Impressed would be to understate the results. Keeping in mind that this brass is headstamped A D I 00 F1 and not "ASO" I can only speak for this batch. If the ASO batch is anywhere near as good, then fill your boots. THIS ADO 00 F1 brass is flawless.
