... my concern is the noise. I know the more power the more potential for noise. Would you consider it (Diana 350 Magnum) backyard friendly? Whatever that means. LOL My guess is no. LOL
..... they're also hard to shoot accurately! your shot to shot form needs to be perfect every time if you expect good accuracy from a rifle like this! JMO
Their loud!!!!! my 460mag in .22cal sounds like a .22cal long shooting!!!! and it's tuned up a tic over factory! if you have neighbors 50yds away they will hear it!!!!!! ask me how I know!!! but if you have no worries about neighbors or scaring off other game {etc} go for it!!! but their also hard to shoot accurately! you shot to shot forum needs to be perfect every time if you expect good accuracy from a rifle like this!
