So my current air gun is a Ruger Blackhawk elite .177cal. (For all intensive purposes, let's say it's a RWS Diana 34, cheap clone) With that being said, I have been able to squeeze impressive accuracy out of this cheap Springer using heavy pellets and a few other upgrades to optics and mounts. But it leaves me wanting more out of it than it could ever do... that being said, I'm in the market for a Marauder, but I can't decide on what caliber. Most important to me is accuracy/killing power out to 75 yards or more. Second most important is noise, will either of these guns be as loud or louder than my break barrel? My dad has a .22 mrod and it is definitely quieter than my ruger. How much louder would a .25 be? Looking to buy within the next two weeks. Any and all input would be appreciated. Thanks.
