Re: mossberg 300 win mag
From the sounds of it I'm guessing you have one of the newer models, I have one of the mossberg 100 atrs in 270. Was picky at first to find the right load but now I've got a good load with the 140 ballistic tips. Seems to shoot and nosler and most hornadys pretty well. Not going to say its a .25 moa gun but I have had a couple groups around .4 most being right at .75 inches at 100. Putting a boyds stock on mine since it just has a plain synthetic on it now so that may help more but as long as you find a good load and have a decent scope you should have a decent rifle for not much money. Hope you like it and good luck with it.
