I am thinking of a leupold vx-iii 2.5-8x36 or similar as it is lightweight and compact. I am not too familiar with what other manufacturers may offer along these lines....i am thinking of keeping this gun lightweight and handy as i will be quite mobile. It will also be used in a varmint hunting situation on occasion(coyote/groundhogs). I need the best bang for the buck as these eyes are showing their age! Light gathering ability is a weighted consideration also....i am open to used scopes as well, all suggestions and ops are appreciated!
