I've had very good results from CCI Blazer... and pretty good price per round if bought by the 5000 case... I've shot over 7000 this last year.. variety of auto loaders...mostly a couple of CMMG conversions for ARs and an Advantage Arms conversion on my G17 with Venom and dovetail mount.
my latest project is the completion of the Ruger Charger project in the PMACA chassis, with a UTG long scout rail... off shore back up front sight and carry handle AR rear sight... the long rail extended the front sight far enough that I can get the front sight in good focus using my upper portion of my bifocals... I use the rifle length AR buffer tube (milled the end flat) as a shoulder support ... the little gun would be an excellent option for someone with recoil and noise concerns... the Charger was started as a proof of concept for a quick handling, relatively high capacity firearm to be used inside a vehicle without hearing protection...
