I also use a sabot gun, and from your discription, you will do well with that nail driver. You will shooting at a target about the size of a perfessional football. The trick is seeing that football location inside a moving 3D target. So always remember where that spot is and you will do fine. Welcome to the forum, You are in a good place. There are prohunters, and life long oldtimers on here, newbees, and techies, riflemen, and shotgunners, stand hunters, ground hunters, and stalkers( here that is a good thing!) I can't speak for anyone but myself, but ask any question, and someone will try to hepl you. Good luck on your first hunt, be warned though, this is an addiction from which you will never recover!
The only real difference between a good tracker and a bad tracker is observation. All the same data is present for both. The rest is understanding what you are seeing.
