17pdr Paper Shot

[Mike Cecil]

'These were used for testing the mountings of guns which cannot, owing to their position, fire service projectiles in time of peace. They are designed to cause the same amount of recoil as a service projectile and to break up in the bore. The body is made of wood pulp or rolled brown paper and is filled to the correct weight with small shot and sawdust.'

War Office 1926 Manual of Ammunition.

Don't see why the 17-pdr would be any different in terms of construction and application. Testing could be done without the need to find a proper range.
