I don't have the Micro Midas but I have a 2017 X-Bolt Stalker Long Range in 30-06 and love it to death. It's a tack driver to 250yds with any ammo I put through it - cheap practice rounds, Hornady SSTs, everything. 250yds is about my skill level so that's plenty. I love the shorter bolt throw angle with the X-bolt's 3 locking lugs, the factory pad is plenty, and it just seems to fit me really well. I don't know if yours has it, but I have that factory "Dura Touch" armor coating and DO NOT LIKE that. It feels tacky even after a year, and picks up the slightest dust from cleaning rags. But whatever.
It would be hard to list all the rounds I've thrown through it, and your caliber is different... But just in the interests of sharing I've decided to go with Hornady SST 165gr (pronghorn and deer) and 180gr (bear and elk) although I've lately gotten some great practice rounds with the same weights from Underwood Ammo, which also has a ballistic tip round like the SST.
Those are a little expensive for 100-round practice sessions, so for those I tend to buy literally whatever is on sale. No joke, if gunbot.net shows a good price on something, I pick it up. My wife has me on a $50 "bullet budget" and I tend to max it out

Federal, Remington, American Eagle, Winchester X, etc. I always buy the same WEIGHTS I'm going to hunt with (and practice with the "good stuff" just before the season) but I've yet to find a round I didn't like. Maybe your standards are higher than mine, but if Browning made yours the way they made mine, it'll eat anything and be hungry for more.
