I hunt with a Howa Mini 6.5 Grendel with the 22" factory taper barrel. It was in a MDT LSS gen1 chassis but it was kind of heavy so I just bought a Stocky's Carbon stock for it and am still waiting for my DIP bottom metal to try it out. MDT is now making bottom metal for the Mini but, if you can believe this, it only fits their proprietary 10 round Mambamag, not the factory mags, which made it a no go for me!
In the chassis I was getting touching 3 shot groups shooting 123gr SST's over a max charge of CFE223 giving me 2704fps over the chrony. It's an awesome cartridge IMHO and a great deer round. The Howa stock leaves a lot to be desired but the barreled action is a for sure winner.
