I've been shooting a number of years (over 55 years) and spent a lot of time worrying about velocity on various rifles. About 25 years ago I decided that it didn't really matter what the velocity was for a given load because they are usually pretty close. One or two hundred fps doesn't really matter to me.
I concentrate instead on group size and midrange trajectory. That's all the deer, moose, elk seem to worry about when I'm shooting at them.
