I've heard the modern hunter doesnt like cheap ammo.... That would be really off putting if the modern Varminter was the same..... That's just a rumor ive heard though....
All depends what you consider "cheap" ammo. My M.H. loves Hirtenberger surplus .308 and at $.79/round I call that cheap. But the rifle loves it all the way out to 800m. But if you're talking "cheap" as in crappy quality, there might be something there.
