I had the same results with the Micro HST from wheelguns - the inconsistent POI drove me absolutely bananas, so I eventually dropped them entirely in favor of Gold Dots for expanding bullets. Re: whether or not the Micro HST is getting discontinued by Federal is anyone's guess - I have a robot that alerts me when they're in stock, and they've bounced in and out of stock on Federal's website twice in the last 24 hours.
