Here in my neck of the woods I would be lucky to get more than a 50yd shot on anything except for one small pasture that is about 100yds by about 40 yds.
So with this in mind i have elected to use a SKS shooting 125gr soft points. I know a lot of people compare the 7.62x39 to 30/30. So from my standpoint this is just another option for you to consider. Plus you can get cheap plinking ammo to practice with.
