OP. are you competing in PRS style shooting? is that why you are asking?
in that case - the comment about relying on your spotter is useless advice. If not competing - then it's okay advice if you have a buddy with you.
tons of us make an effort to watch our own trace through the scope when competing. It's definitely challenging, esp when not in the prone.
The good shooters almost all can see their trace (on trace worthy days) on a majority of their shots. It really helps you adjust your wind call on the fly.
it's easier in the prone - so I'd start there. you basically have the gist of it. It just takes practice on where to look for. once you start finding it - correlate where in the scope you are catching it vs. what elevation you are dialing - take note.
being able to see trace is one of the skills I believe separates the top shooters from the rest of the pack. you can't always see your "splash" or miss. (wet ground, target on a hill and the the bullet is splashing 150y behind the target, trees/brush behind target, etc) so being able to see trace yourself can tell you a lot of information on where your bullet just went.
