well i have a very nice mini 30 that i like a lot with a nikon 4 power scope. at 50 yrds it will shoot fairly well, at 100 yrds the groups really open up to like 6 inches.now mind yu this is with russian ammo and ive never handloaded for it.its very handy, totally reliable but id say 200 yrds is really pushing it and if your going to 300 yrds yu better shoot a lot at that distance and id suggest a mil dot scope.heck my 06 bolt guns drop 14 in or better at 300 yrds with 150 grn bullets in handloads.if your shots are really under 100 yrds id not be a bit afraid of the mini 30. over that id really have to work up sum loads with premium bullets.there is plenty of info on the net about accurizeing the the mini type rifles.to be honest for the same or less money id just buy model 7 rem and be done with it.
