Always seemed smart to me to practice beyond your range, that way whats in your range is really gravy... we used to shoot 90-100 yards quite a lot in the 70-80s. Made a lot of sense.
And as noted, every day can bring other issues, especially with a rifle.
Only way I'll extend past 15 with a bow is if htere is "cover" noise that someone else mentioned and conditions are right... and that won't be on anything other than a meat type animal, not a trophy type. I actually expect I'll never ever extend it again as the last time I did, on a trash buck I needed dead before he could breed, I had cover noise and life was correct and he jumped the string and was a bad hit. Luckily I got him a month later with a 308...
