This weekend I killed a boar with my Brow 270 wsm (which by the way wasn't grouping very well) and the round didn't even go through opposite side of the 130 lb boar[:'(]...I was shooting the Winchester Supreme 130 gr bst's & I though that it would have been plenty. I hit him square in the vitals and he still managed to run about 15 yds. Should I be using different ammo for hogs? any sugestions would be great, thanks.
