I'm more of a slug person. I like using the Winchester PDX1 slug/buck shot combo. Seems to be really nasty.
I also like the Winchester deer slug. It feels powerful when shooting and it hits dead on out of a cylinder bore. Seeing the type of damage it does to a deer and the fact that it flattens to a near 2" solid lead, I just can't help but feel safe with it.
I tried the buckshot and the Hornady critical 00 is my favorite but the Remington 00 buckshots seem to have the tightest group at 25 yards. The winchester 00 military buckshots seem to have the worst. Only problem is it doesn't feel as powerful as the deer slugs. After shooting a case of deer slugs, the buckshots feel like a .22 to be honest. The Hornady is the most powerful buckshot but the Remington and the military buckshots seem to be the weakest feeling.
