Accuracy was phenomenal with 2" five shot groups on steel at 760 Yards. The other was built on a TikKa that was originally a .22-250. I put on a Shilen #4 chrome moly 8 twist match barrel finished at 24" This was built for long Range Coues Deer and is also running the 105 Hybrid with 39.5gr of H4350 at the same 3050fps and excellent accuracy. In my limited experience the sweet spot sure seems to be right around 39 grains of powder and 3050fps. Your milage may vary but I have plans to buid one of my own here soon because it is such a sweet little round. In both cases I couldn't make these rifles shoot groups much bigger than 1/2" at 100 yards. It is a very inherently accurate and forgiving on the load development side of things. Hope this helps.
