Called Talley today... Kimber 8400 X-lows are being made right now and will be available in a month.
I'll be putting a pair on my 300 WSM.
Aaargh
I WAS happy with the Talley lows on my 8400 but now I gotta wonder...
My M700's are a no brainer; extra-lows will be procured.
Good news, I guess, that they exist now but I'd just gotten everything converted to Talleys in the last year plus. Now I need to decide what needs re-converting.
