I gotta say that many of the rifles shown here are HEAVY for hunting rifles to be carried for hours in the field.
As you can see (on page 11) I have a light rifle. That 6.5 PRC X-Bolt Pro has a carbon fiber stock, fluted barrel and bolt, light Talley rings, etc. and comes in at 6 lbs. 3 oz. "naked".
My one concession to weight is the 30 oz. Bushnell LRTS 4.5 - 18 x 44 scale with illuminated G3 reticle. I wanted mil/mil turrets and that reticle and an illuminated abbreviated Xmas tree reticle all in a quality scope. That scope had all those features but 30 oz. is not a "light" scope by mountain rifle standards. However it does have the necessary magnification for hunting in Nevada. I could have saved 2 oz. by going with no illumination but illumination is vital in some situations like a dark background or in a dense woods on an overcast day.
Maybe some of the heavy hunting rifles shown here are "bean field rifles" meant for hunting from a tree stand. I hope for their owner's sake that is the case. Otherwise they are going to need an ATV to haul them around.
