Who is anyone to say what IS or IS NOT a hunting rifle.
I'll say what I said in the last post regarding this challenge.
I'd be willing to bet my LIGHTEST rifle is 14lbs and my heaviest is around 22 lbs.
I hunt with them all, by definition, that makes them all hunting rifles.
A hunting challenge where you artificially limit equipment is just as stupid as limiting weight. I have a bipod, tripod and pack on 100% of my hunting trips. If you need to get off the ground in order to see the shot...it's very easy to deploy the bipod, and use the tripod for a rear rest and/or the bag for support.
Hell. Take an MDT Triple pull, with your tripod and you can essentially take prone shots standing up.
