Premium/white label JSBs (Daystate, AA, FX, etc)

[Larcat]

Does anyone actually know the deal? Have extensive testing experience? Are they all the same thing, or do they differ?

I've read everything from "AAs are a special die only used for their pellets" to "single batch run normal JSBs" to "pure white label, same damned thing."

What's the deal?

maybe they meant the old gray label jsb.


my understanding for fx pellets,
they are jsb's from one die only.

not sure about aa or daystate,
but probably along the same lines

My understanding (from JSB) is that the re-brands have their own die(s), whereas the "JSB" labels are made from 8 or 10 different dies, if I recall.

Interestingly, for me, the JSB labels seem to run just a bit better in all of my guns. This is even when shooting FX labels in an FX gun. YMMV.

Larcat,
Best way to understand the JSB/AA/FX relationship is to watch Steve's AEAC "JSB Facility Tour" video from 2019. Can be found on YouTube, towards the end Steve has a "MythBusters" discussion with a JSB owner where things are explained. WM

In a nutshell, JSB decides to make production run. They bring out the dies and set up eight machines. Different ages of machines and dies, as well as other manufacturing factors cause pellet sizes and weights to vary slightly. To address this JSB mixes an assortment of pellets from various machines in each tin. During that same run, JSB decides all pellets from a selected machine, let's say Machine #6, will be FX brand. It's not that Machine #6 is special to FX, JSB could have chosen Machine #4, just that the many variables from different machines and dies that vary pellet size/weight are greatly reduced and FX pellet consistency is improved.

You're welcome, Sir. Explains why members who size and weigh pellets from a JSB tin always seem to find a wide variety. Also, explains frustrated members who purchased pellets from Classifieds only to find overweight/oversize and underweight/undersize pellets in the tin, the seller having conveniently removed all the "in-spec" ones for personal use. Borders on a scam, IMO, unless specifically stated up front, what had been done. WM

@WorriedMan.

Got around to watching the whole video. Wow.

Also the second video of AEACs I've watched. Super high quality, informative, very "web 1.0" style stuff. Enjoying it.

Thanks again for the tip.
