A firm grip on the NONEL tube or leg wires must be maintained while loading to
prevent the loss of the initiation line.

Priming Requirement - The TROJAN Ringprime Cast Booster is reliably
initiated using a No. 8 strength detonator. The TROJAN Ringprime Cast
Booster is 10 g/m detonating cord sensitive - although it is not a recommended
practice to use 10 g/m detonating cord in the hole.
