The relative prior art of the technical program also has following advantage and effect:

The firing operation method, use firing table, fire accuracy identical, can replace live shell to carry out gunnery training and examine training achievement with live shell;

When shooting, all can in 1500 meters scopes, see the projectile flight path clearly with No. 0 or No. 1 powder charge, the position of falling after the position of hit and the knock-on, thus satisfied the requirement that projectile is observed in gunnery training;

Knock-on can force rate prior art strong, the ground of all bouncing out effectively, all places except that marshland, water network and paddyfield area and stony ground has made things convenient for the selection in place;

All parts except that priming system are all reusable, and are under normal circumstances reusable more than 50 times, can further save a large amount of training costs;

Fuse has the duties insurance function, can guarantee that shell with fuse vertically lands from 2 meters eminences to misfire, and makes dummy round more safe and reliable;
