I never shoot reduced loads. But that being said I rarely shoot maximum loads either. But what I consider maximum a lot of times differs from the maximum listed in many reloading manuals. My rifle will let me know when I'm approaching its maximum safe load.
The reason I rarely load for maximum is that most times my accuracy is better somewhere below max. I've only had one or two rifles that shot well in the upper limits. And I say I never shoot reduced loads. Why should I? If I want to shoot a milder round I'll choose a lighter caliber from my gun safe.
