I have the thumbhole version. I shoot 110 gr 777 under a 200gr Shockwave, and have taken deer to a longer range than you probably are prepared to practice for. Great gun.
I did, however, have to get the .25 ACP conversion from Precision Rifle. Without it, the crud ring made the fun unshootable with 777. BlackMag3 was not available when I got the gun; maybe using BM3 would make it shootable with 209s.
Also, as supplied, the point-of-impact shifted if I took the action out of the stock for thorough cleaning. I had to install aluminum pillars and resin-bed the action (and free-float the barrel). After these modifications, the gun became an unbelievable tack-driver!
The gun was fairly picky with loads. It generally shot the 200-250 gr Shockwaves well under 110 gr powder though.
As an addendum, I find the gun great for prone and bench shooting. However, the thumbhole stock is less than ideal for kneeling and offhand shooting; I tend to get my face too close to the scope and bean myself on the forehead. It just feels ungangly offhand.
