Scenar are great rounds. I have had a few rifle that didn’t like them thou and wouldnt hold groups very well. I would try them out before buying in bulk. Also like said above the price is an issue for me.
I prefer the 300 WSM. I have shot accurately out to 2200 yards (probably would do much damage out at the range but the cartridge has the capability. 1500 no problem on a deer.
I learned early in this sport that it is better to spend a little more up front and get the best optic that you can. I would save up for the gen II razor like said by others in this thread.
