Another newb ? .300 AAC brass

[Longcarbine]

Been looking to buy some .300 blackout brass and found what I think is a good deal, here is the websites description.

"100 pieces of 300 AAC Blackout brass that was converted from once fired Military auctioned .223/5.56 brass mixed headstamps. LC,TAA,WCC,etc This brass was tumbled in stainless steel media. It has also been full length resized, deprimed trimmed to SAAMI spec, primer pocket swaged, then tumbled in corn cob/walnut media. This brass is as close as it gets to new brass"

I had read about military brass primer pockets being shimmed and needing re-worked before being re-primed. My question is, is this brass good to go for re-priming.

Primer pockets dont need to be "shimmed".
Military brass comes with crimped primers to avoid them backing out.
To reprime you need to remove that crimp, swaging is a process to accomplish that where you force the primer pocket over a form to press the crimps away. Reaming is another more elegant solution that removes the crimps.

That brass should be good to load (though it is mixed headstamp and will be an assortment of lengths and thicknesses making it crap in my opinion, if just range blasting ammo who cares though)

Just for plinking in my Ruger bolt action, maybe some coyote hunting.

After doing some searching I have decided to go a different route. Bought a mini chop saw and jig to convert the bagillion rounds of .223 brass I have into .300 blackout, should be cheaper in the long run plus it gives me something to fiddle around with.
