Is nickelled 223 brass easily available?
 

I am considering a second 223 rifle. I prefer fire formed cases for reloading. To segregate the two rifles loads nickelled brass would be easy and ideal.

Further research suggests problems with nickel cases. Brittleness, flaking, and short life, opinions?

Never did comparison testing with 223, but I did with the yellow and nickel plated stuff using Fed Gold Medal 308. With moderate loads, I started getting neck splits sooner with the nickel plate and discarded yellow after 13 reloads and nickel after 11. I never had any issues with flaking, scratched dies, etc as some reported.
If you FL size, the fireform rationale does not really come into play. I personally have not noticed any significant downrange performance difference between FL and NS reloads. Granted, NS requires less case prep and may also extend case life a bit.

I have reloaded nickel as well for decades with no issues.

Some mixed results here. I've found it to be a PITA for some of the reasons mentioned.
If you want to segregate, do it by head stamp. W-W for one and Remington in the other for example.

Seems some have concerns and some don't. I've decided to not bother after all. Thanks.

How do others handle this?

I sort by head stamp and then store in the different colour MTM casegard cases. Green for my semi and blue for the bolt in same caliber, etc.

Some HPBT and others in AMAX so just looking at them I know which rifle they are for as well.

Right now I have 3 loads in 223. Blue cases are 50gr, green is 55 and red is 75gr. The casegard cases come with labels that I write the load info with powder on as well on each box

As mentioned above i ise different brands of brass or try to use visably different projectiles like in my 2 6.5x55's one shoots berger the other sst's very easy to distinguish them
Also none of the that matters if you are well organized and diligent in separating everything
It gets more interesting when you form from other cases like myself with my 338-06 from 30-06 and my 358sta from 8mmrm or 375h&h
And have rifles chambered in the parent case as well

Keep your brass separated in MTM cases and mark them by which rifle they belong to. Pretty simple system and not subject to much for problems unless your are REALLY disorganised.

Exactly ^^^^
