Hello everyone and Merry Christmas. This is my first post on this forums and im wanting to make my 25-06 the ultimate long range rifle. I use my 25-06 for groundhogs, deer, coyote, and other varmints. I reload and im shooting 115 grain nosler balistic tips. Its already a accurate rifle as it stands. What all should i do to kill a groundhog at 600-1000 yards?
