I own a .22 marauder and I've tuned my friends .25 marauder. If you want long range shooting without modding, get the .25. You will probably end up modding anyway because the parts are cheap and easy to get. With the .25, you can expect 16 good shots at around 37 foot pounds of energy and get around a 3/4" group at 50 yards. Anything after 50 yards, it seems like on paper it opens up a lot but when you have a critter in the crosshairs past 50 yards, they always seem to drop. The only thing I've done to my .22 is install a Marmot Militia hammer forged barrel and it was well worth the money. I went from a 1 1/2" group at 50 yards to a sub 1/2" group using 18 grain JSB pellets. I'm getting just over a 1" group at 100 yards. I'm getting 20 shots at 33 foot pounds with a 20 fps spread and if I drop the tune to 30 foot pounds, I get 30 shots per fill with the same 20 fps spread. For me, the .22 was a better option because of the shot count, but the stock barrel only likes Crosman Premiers and 40 yards is the max I would shoot out to. With the new barrel, If it's within 120 yards, its dead. In the end am I glad I went with the Marauder? Yes. Parts are cheap and easily attainable. Tuning is easy once you learn how to do it. If you don't like something on the rifle, there's a good chance you can find an aftermarket part to improve it for cheap.
