I am trying to decide which rifle to buy. A Beeman R7 or it's near twin , the Weihrauch HW30 ? Weihrauch makes them both , but are there slight differences that make one better then the other ? Two of the major dealers in American list slight advantages in weight (5.5 to 6.2 pounds) and the ever constant war of velocity. Of course that battle could be resolved by what pellet is being shot out of which gun ? So which one to buy , and why ?
