I tried myself. I was REALLY biased and tried to make it work and was never happy with it. I bought a Springfield Loaded model, started with it. I did all the standard accuracy tweaks everyone recommends, shimmed the gas system, Sadlak guide rod, NM piston and and bedded it in the stock. That resulted 1.5ish MOA at best but not really consistently. I then went to a Sage chassis and essentially made it an M39 EMR clone, I loved the rifle like this, other than being really heavy. I did a metric TON of load workups and FINALLY got a load together with 168 Amaxes that would shoot about 1 MOA fairly consistent but would still occasionally just launch a flyer for no apparent reason. It was extremely picky about the ammo needed to make it shoot good and I just eventually ran out of patience with it. I was neck turning brass and spending a ton of time on case prep and just got tired of it. I shot one 600 yard F Class Mid Range match with it and had a good time but it was just so brutal on how it treated the brass it was way too much work.
I sold the chassis and put it in a USGI fiberglass stock and just accepted it for what it is and enjoy it for that. I kept the Sadlak scope mount and occasionally throw an Aimpoint on it and shoot local 2 gun matches with it BHD Shugart style. I really wanted to make it work because I love the platform but in a precision role I was never happy with it. I went down the 308 AR platform and built a precision rifle that will flat shoot and not be as picky about it.
Hope this helps, this was my experience with one. Someone could maybe go with a good barrel with less tight of a chamber than my Loaded has and see better results but I just didn't pursue it any further.
