Similarly, my Sig 277 Hybrid case's volumes measured at 57 grs H2O. I'd received 4 different case headstamps of them and each was a little different. After necking them up from .277 to .308 and firing them, two of the headstamps measured at 57.7, which interestingly is exactly what my Winchester .308 brass measured.I received a batch of the Shellshock 308 Win casings. The company has zero communication skills. I left several messages via email/phone and received no responses. I also received zero shipping info but the brass did arrive after 6 days so not bad but the lack of communication annoyed me.
The brass itself looks terrible. Its filthy unlike the photos they provide on their website where it all looks new. What I received looks like 5 week old nickel range brass. Pretty ugly.
I threw some of it in the stainless media to clean it up. We will see how it turns out. The annealing marks are almost 3/4 of the way down the case length....kinda weird. The 300blk casing I bought previously looked MUCH better.
My only guess is that they coat them in some kinda of oil during packaging. The bag is covered in it.
The interesting part is the H2O capacity. My alpha (unfired) srp brass holds 54.8 grains of water BUT the SS Nas3 holds 57!!! That is a massive difference.
My plan is too load some up tomorrow with my current 308 recipe and see how it goes.

It’s something that is useless unless you want to play mathematician. When you are laying behind your scope are you figuring out the apparent FOV? No. You see what you see. Seeing as this is the first I heard of this super important specification and never needed it to hit what I was aiming at then that will be filed under useless info for me. You have fun with your calculations![]()
yup, run off the happy eaters who like to tip ...for bitches, and pretend bitches who like to bitch and don't tip.
Pretty sure it has to be filed hard copy/ paper form 4 forin state NFA item transfers.Who's submitting the form 4??? ATF efile doesn't allow an individual submit a Form 4, says you need to be a FFL/SOT when you click on Form 4.
I tried yesterday...
