I'd like some opinions from those who have owned this rifle. H&R Buffalo Classic Rifle 45-70 Government I'm mainly interested in the action strength and overall sturdiness. I also would like to know about that Williams receiver sight, it doesn't look like it would offer much in elevation. Would it have enough elevation to take a subsonic load out to 400 yards? I have another question that is more reloading specific... how fast can one push a hard-cast bullet? Thanks in advance!
