I shoot between 4 and 500 a lot ,I really enjoy that range actually for some strange reason I really like 450 yards, my own purposes have been just my own enjoyment, not been competing yet ,I like to take all of my really shiny 100 yard loads out to 400 and 450 I feel fairly confident at that range,, but I only because I shoot at that range a lot, I feel like I could put bullets on my palm with the multitude of rifles that I have in 45 Cal whether 18 twists or 20s both twists will do that, I have rifles that will do that with plastic for me it doesn't take long to get comfortable at that range and feel very comfortable with doping wind it's when I move out past 500 to around that 600 yard range things begin to change. It's hard to find a place to shoot for most people but I do encourage you to have a chance to stretch things out learn to shoot out to four and 500 yards I think it makes you a better shooter myself and to me it gives me confidence in my rifle when I'm shooting 300 yards and in I can think of many reasons to practice long even though most of the time I shoot short when I'm hunting in the process of learning your weapon I don't care what it is 50 cal or 45 28 twist or fast twist if you get a chance to shoot that rifle at further distances I think you should try always learn the limits of your weapon
