GONRA, did you trim yours down to reloading length? Mine are just a hair long, in the 1.137-1.134 range. They are also demonstrably narrower than the factory brass by around .003". The factory measured in the .312-.3135" range while EA brass is .309. Every single one of them was exactly .309, I might add. No variation. All measurements were taken from the base of shell casing, just before the head. I will try them at 65% of my normal load, which would be 4 grains of 3N38 on a 40 grain Nosler ballistic tip. I may try up to 4.3 as well. Let me know when you have chrono readings. I'm interested to see your velocity in EA brass vs. factory.

GONRA just loaded em up. Didn't measure anything - yet.
(Using FN brass, my SMALL BASE RCBS dies resized exactly to Factory Sample cartridge diameter specs.
Remember, use a MICROMETER for diameters, electronic caliper is OK for LENGTHS.
So, will have to see wot happens with this brass.....)

Hava LabRadar Doppler Chronograph, but am still climbing the learnng curve
and don't wanna screw with it on a busy range -
local club range is Really Crowded these days.

Will be quite a while before I have more data.
Am sure extensive / really good data you can trust will be posted by the usual experts on this web site....

And it should be common sense this is why the brass manufacture is always stated for re loads.

Little bit off topic, but Jay, did you ever hear back from RCBS about the shell holder?

Not sure wot the shell holder issue is, but RCBS #45 verked Just Fine for GONRA's EA 07 brass priming and loading.

Traditional FN brass FIRED MT's weigh nominal 60 grains.
New EA 07 brass FIRED MT's weigh nominal 75 grains.
(Remember, these weights include the fired Boxer primer.)
Advanced theoretical thinkers out there can figgerout how to best use this for sorting fired cases,
especially the piles of 5.7x28mm FN brass littering most ranges.

Talked to them live.

RCBS refuses to sell the parts needed to use their old style plates and allow customers to swap back and forth as needed.

They stated if your brass is slipping in their new universal holder to call them.

Brass arrived fine. Looks good with the EA stamp.

Image

Brass after firing. Most have very little shoulder movement. 2 have normal shoulder movement.

2 with normal shoulder movement.

Rest without.

Primers look normal.

I had to ditch my Lee resizing die. I tried it on one virgin case and it cracked the neck. Went to lyman and it worked fine.

It's where the shoulder was pushed forward, but it did not expand to the diameter of the rest of the cartridge, so there are almost two separate shoulders there. That's what the ring is.

Were these fired from the FsN or the PS90?

I may have missed this answer previously, but is this brass annealed?

Of course, all new brass has to be.
It is coated also.

How do you recommend cleaning the EA brass to protect the coating?

Clean same as FN brass. Simple green mix etc.


When we can keep up with demand for loaded ammo we will sell PFP bullets again .
