I'm relatively new to CAS (3 years) but I have adopted the same expectations I have always had for all of my hunting and target rifles and pistols. I always bench and zero each firearm to my desired range. I also experiment and keep records with factory, surplus and reloads as far as accuracy, function, recoil etc. Once I find the best combo then I work on my part of the equation. I do not deal well with any firearm that does not shoot where it is pointed. I have run into some poor shooting guns in my time. Most issues all able to be resolved with a little work, especially on stocks or sights. The few I could not convince got disowned.
For my CAS rifles in 45 Colt I Have no trouble with accuracy, especially at the close ranges, but you can bet, where I point the bead, the bullet will go. For my pistols, the same. No Kentucky windage for me.
Just a new guys thoughts.
