Welcome Eric! This is a fun and really helpful forum. I started out with a .25 marauder and a hand pump, it’s hard to pump but with the right technique you can do it. I’m remembering around 60 or 70 pump strokes to top off the marauder, giving around 30 good shots, hopefully I remember correctly. And I was very impressed with the accuracy of the marauder too. As well as the trigger and how quiet it was. Thirty fun powerful accurate shots is definitely worth the 70 pump strokes lol! Have fun and keep us posted on your choice of gun…or should I say guns because you are definitely about to get bit by the airgun bug.
Oh yeah, the Benjamin mrod is a great gun, I have one in .177 and it's fun to shoot. I bought an Air Venturi Portable 4500 compressor to air it up and the little compressor does a great job (on my other PCPs, too - I used a hand pump once, and that was enough for me). I have a chronograph and like to run ran numbers as I shot my air guns
