hi guys...i have a remington 700 PSS that i'm interested in learning to shoot well in the 500-1000 yard range. i'm not a hunter or professional sharpshooter,this is simply for fun.i have a mil-dot master,ballistic cards,etc. and i pretty much understand all that, at least in theory. on a foolish whim, i bought a smith and wesson scope that i got really cheap (4-18X,42mm.) but after reading up on the internet,i'm thinking something else may be more ideal. i'm looking for the best quality glass i can afford,mil-dot reticle,parallax adjustable,target knobs and high internal adjustability. i know this stuff ain't cheap, but cost is a factor,this is after all,just a hobby. i've considered several options that i've seen recommended here ( nikon buckmaster tactical,bushnell elite tactical,super sniper,etc.). i'm possibly leaning towards something with fixed power,is 10x enough? also,if i get a 1" tube, will i later be wishing i'd gotten 30mm? i'd like to spend less,but the 20X mk4 leupold for $669 i just saw recommended was tempting, but isn't that way more power than i'd want,even trying to get out to 1000 ? anyway,all advice,either general or on specific scopes for my purposes will be much appreciated......
