Cast off for a righty that doesn't need it is just as bad as not enough for someone who does. If you can't mount the gun with your eyes closed and, when you open them, be looking down the center of the rib it's not right. I can mount a gun three times and tell you if I can shoot it well, or not.
Every person is a different case study in fitting. For example, I'm right handed, but the buttstock on my MX8 is built for a lefty. It has obvious cast on. I slid the adjustable cheekpiece as far to the right as it would go, which wasn't much, and it was perfect. But, I have a very skinny face. Been shooting it for some 8-9 years, now.
