New to Precision Rifles

This is at 25 yds. I wanted to use the 50yd range but it was full. I’m just curious is this a decent start? These smaller targets are also intended to simulate a further range target correct? At 25 yds, the little head which is about 3in in diameter would be equivalent to a normal sized target at how far? Sorry for all the noob questions. I am very excited to practice further distances going forward. Thanks in advance!!
