I have one in .45-70 GOV'T & another in .308 Win.
For < $500 for gun + scope what do you want?
They're not going to shoot like $5000+ custom rifles with Schmidt & Bender scopes sitting on top of Surgeon actions & Krieger barrels. If they did bench rest shooters wouldn't be ponying up the big dollars for precision rifle/scope combinations.
If you can get an honest 2 " group @ 100 yards with one of these clunkers consider yourself lucky.
With iron sights or a Tasco or Simmons scopes on them they're el-cheapo meat-getters for the financially challenged that will shoot MOH (Minute-Of-Hog) & fill a freezer........that's as good as it gets for less than $500.
I'd like to encounter one of the guys who claim consistent & repeatable < 1 MOA with a NEF/H&R single shot at the range & bet him that for every "called" 1 " or less 3 shot group at 100 yards he fired I would pay him $100 & every time his group size went over 1 " he would pay me $100. I'm betting the guy would find an excuse to have to go home before a single bullet traveled down range.
