I would recommend you get your hands on one of those M52's before you buy one. They are a very big and heavy rifle. Powerful and accurate when shot properly - that kind of power is best served in .22 cal and by an experienced airgunner IMO.

PCP's are cool but you have to get the air in them somehow - hard to beat a springer for simple shooting.
