I've got two .444 Marlin. One with a microgroove barrel and a newer one with the ballard rifling. Haven't shot the newer one yet but the microgroove one shoots under 1" at 100yds with the Hornady 265gr FP and 300gr XTP and the Speer 300gr UC.

I just installed a grey laminate on my newer one. Once I confirm that she shoots as well as my older one, I'll probably only keep one.
