17 Mach 4 same as Remington 17 Fireball

[H. Milliron/W.Tabor]

Twenty years ago I had a 17 Mach 4 built on an XP 100 blueprinted action mated to a HS Precision stock and Dan Lijla barrel. Since then Remington has come out with the 17 Fireball. Can I shoot factory 17 Rem in my 17 Mach 4?

Cartridge	Parent Case	Case Length	Typical Chambering Compatibility
.17 Remington	.223 Remington	1.796"	.17 Remington only
.17 Mach IV	.221 Fireball	1.400"	.17 Mach IV (and sometimes .17 Fireball with caution)

Close, yes. Same, no.
