I've never used them. Same goes for changing to a musket nipple. Not needed.

Thousands of successful shots and still countingwith the standard nipple on T/C Rifles.

The hot shot came about really for use with Pyrodex (becuase of the highflashpointof Pyrodex)and also for inlines with nipples to ensure more reliable ignition.

I'm not personnally a Pyrodex fan.

Swiss Black Power in 3FG, 777 3FG and Black Mag'3 all shoot excellent with T/C Caplocks and the standard nipple.

Also, RWS Dynamit/Nobel #1075 caps. Best I've ever used.

If you keep the flash channel and nipple clear by picking on occassion, you should not have any ignition issues.

IMHO
