I'm brand new to this forum, my name is Chris, very nice to meet you all. I'm posting here because I've gotten very little feedback on other forums I belong to, so I thought I'd bring my thoughts here to see what folks in this community think.
I've come across a large lot of newer Armscor (A USA) brass. Not knowing much about it, I've started doing some testing to see what it's all about. I've been very, and pleasantly, surprised...so far.
Here's what I've learned thus far.
'Torture Testing 101': I've started to test the reloading limits of a 10 case sample. So far, only 5 firings, so not much to report here. I resized it, trimmed it to 1.750, and started loading/firing. Average case length stretch so far is averaging around .003 after 5 firings from a semi-auto (AR). No cracked necks, etc....but I wouldn't expect this yet. I plan to continue this testing as time allows...and will report back.
Case weights: A 10 case sample varies between 97.5 and 100.1 gr. Not super consistent....so this concerned me.
Web thickness: LC 12 averaged around .185. The Armscor, around .183. Pretty close, and again, surprising.
Now the interesting part: Case volume. I took a 10 case sample of the Armscor brass and a 10 case sample of LC 12 brass. Resized, trimmed to 1.750, weighed dry and then filled with water and weighed again. Here's what I found.
Armscor averaged 30.65 vs. LC 12 at 30.96. So the Armscor brass averages about .31gr smaller capacity.
The most interesting part of this was the consistency. The Armscor varied from 30.3-30.9, so a range of 0.6. The LC 12 varied from 30.4 to 31.4, so a range of 1.0.
Can this Armscor brass actually be comparable, and possibly more consistent than LC??
I'm having a hard time believing it, but wanted to share, and also ask if anyone else has tried this brass, or if anyone else has put it through the paces to see how it might measure up.
Hope to hear some feedback on this....I know it goes against convention, but that's why I'm testing it!!
