I am going on a hog hunt at the end of this month and don't have the time or dinero to buy a new rifle and get it sighted in. I'm currently using a weatherby super varmintmaster in 22-250 w/ winchester 40gr ballistic tips. What advice do ya'll have on shot placement and the size of hog I should attemp to take with this caliber? The rancher says a wall hanger 300 plus is no problem - should I stick to the smaller meat hogs or break out the mossberg 12ga w/ a slug barrel?
