Which rifle is the best of these three

This is the book definition of versatile. “adjective. Competent in many things; able to turn easily from one subject or occupation to another” I have in my time had many of each of the '03, and 98K, and tested each one before they were put on the shelf of my shop. They are in most ways neck, and neck. though I did find the '03 to be more inclined to make a tighter group than the 98, that quality being even more pronounced at greater ranges (more than 300 yds) This is for the as issued military rifle. Either action would make a good foundation for an effective sporting rifle, this depends of course on the competency of those who did the conversion work.

Was there ever any question? K98!!

Although not on the list, as a battle rifle that can be used for sniping as well I would still favour the No4 Lee Enfield.

Rapid fire with a very smooth and quick to operate bolt, 10 round magazine charger loaded, reasonably accurate as standard with selected ones making very good snipers rifles.

Think outside the box.
