NEED those minimum energy figures, or you PREFER those? Nothing wrong with personal preference.
If you think they're needed though, I'm curious as to why, since you already stated you need a good bullet, which I agree with that. A truly "good bullet" will work well even with much less energy potential than that. And some bullets still don't perform well with more energy potential than that.
Again, there's no issue if that's simply your personal preference and what works for you. Saying or implying we all need to be at those numbers is what I'd say is inaccurate.
Not trying to be a jerk or be petty, just trying to clarify.
