I was told that when you put a scope on a rifle you should sight in at at 25 yds before goig to 100 yds. Is this true.
Generally speaking, I'd say yes, but the idea seems to be making sure that you are pretty close before you go to longer distances for the final, finer adjustments. It saves time and ammo.
As a rule of thumb, a typical "hunting rifle" centerfire rifle, shooting with typical hunting style bullets, will have the line of sight, and the line of trajectory, cross at roughly 50 yards and then again at roughly 200 yards. If you follow the maximum point blank range philosophy, that puts you inside a 4 inch circle the whole way using a single sight picture. For our handgun cartridge firing lever guns, and their less ballistically efficient bullets, those distances are roughly 25 and 75 yards. Of course, you should confirm those with actual rounds downrange.
