In Alabama, deer season extended into rabbit season. I sent the slug down range 40 some odd yards. It entered at the jaw and exited out where her navel would be. I witnessed a 20 gauge 2 3/4' slug passed through the body of a doe and dropped on the spot. These sub 12 gauge slugs at 2 3/4' are not to be trifled with. If a bear or mountain lion are close enough to require dispatching, a 28 gauge slug to the head should do the trick with a second one behind the first just to make sure. If I want to punish myself, I'll load up with some 3' mags though I do not need to. The loss of 75 - 100 fps at 35 yards will not be noticed. I am really going to enjoy handling this lil gun in the field and at the range.
The feel of CZs G2 Bobwhite in 28 gauge is superb. I absolutely love my Merkel 40E 28 gauge. Now that the 28 has claimed its place in dedicated frame size. There's something off about the 28 gauge sitting on a 20 gauge frame.
