Looks like they now offer .308, 7mm08 and .243. Which decides the Predator vs SPS decision for me!
Just to clarify, you're referring to the Predator version of the AMERICAN; the Model 77 HAWKEYE Predator is NOT made in a left-handed version at present.
I've been pestering them for a couple years through their Tell the CEO website. Don't understand them offering niche left hand options but ignoring the high volume rimfire segment.
