I do most of my practice at 25 to 30 feet, but on most range visits I will run the target out to 75 feet (the max at my most-used range, indoors) for a mag or two out of one pistol. It is a good thing to challenge yourself a little. It's not that hard to get hits at that range with just a little practice, and it reinforces good technique. I'm to the point that I can keep shots on the head of a half-sized silhouette even with my smallest regularly-used pistol, a Sig P238. A couple of them might be closer to piercings than to stopping shots, but the ear is still part of the head, right?
("Smallest regularly-used pistol" excludes my inherited Libia, a little .25 modeled after the 1906 Browning Vest Pocket Pistol. With that thing, the best way to hit the side of a barn is to be inside the barn, and even then you might need to bench rest it.)
