I am looking to replace a scope I have on my Rem 700 22-250. I want a Leupold 8.5 x 25 x 50, 6.5 x 20 x 40, or last a Bushnell 4200 8 x 32 x 50. Any of you varmint hunters use the varmint hunters reticle? I like the higher magnification, and if I could afford one I would buy a 45x Leupold. What do you folks like for magnification for shots at and beyond 300 yds for varmints? Thanks.
