Investarms Gemmer Hawken flintlock in .45 caliber

[JDBraddy]

Was thinking about trying one. Anybody have one?
How's the quality compare to T/C?
Is it 1:60 like larger calibers, or 1:48 like the Bridger and carbine?

I would guess it's 1:48

According to the Investarms website, the Investarms Model 160, Gemmer, will have a 1 in 48" twist for the 45 caliber or 1 in 60 for the Hunter version which is 1 in 32.
