I have an R8 professional success. Relatively new to it but it is bloody accurate and very fast for follow up shooting. I have a 6.5 x 55 barrel paired with a ballistic turret swaro z5 for use on deer and a 3006 barrel paired with an aimpoint H30s for general walkabout hunting and pigs. Very happy with it thus far. Have taken bunnies, dogs, pigs, and chital with it thus far. I use it for all of my medium game / routine hunting.may take it for chamois later this year too.
