I've got one of those, mannlicher style stocked, 20" bbl, in .30-06. The stock on mine had been shortened (bummer) and a nifty redfield peep (?) and brass sourdough sort of post installed as sights. A new pad brought the rifle into a better fit for me, and I loaded a bit for it. Dang thing is a shooter. I went with 200 gr Noslers (don't ask) and its first 3 shot -100 yd group with the peep went about 1.25 ". It also kicked like a mule.
Before my eyes get any worse, I will kill deer with it.
The Mark X's are dandy commercial mausers. Safety is not true Mauser, but suits me.
