It depends on where you hunt
How long in area you're hunting? I'm going out tomorrow morning (Sat 12/14) to hunt deer in Iowa's 2nd gun season, temp is supposed to be -2/-4* F Sat night. Used to be shotgun slugs only in the two main firearm seasons for whitetail, but a few years back they legalized .357-.500 straight wall cartridges. Most guys around here used to use the same 28-30" barrel used for bird hunting before slug barrels came about. I use a Marlin 94 Cowboy model octagonal 44 Mag rifle. Sorry-no Savage 99, bottle neck cartridges not allowed. Such rounds as .444 Marlin and 45/70 are legal. You can use a handgun, but don't know many who do. My 44 Mag will drop them fast, never liked using slugs. I'm a bow hunter at heart, have taken my muzzleloader out a few times in the special season they are allowed. I have several whitetails in my area that have some nice wide antler spreads, saw one of them this morning out driving around, saw its brother about a week ago around 75 yds out in a combined corn field just south of my house. Teasing me. Most others I've seen are what we call 'Floyd County Bucks', named for the county I live in. They're just average size having 6-8 point racks of average size. That's both racks for you western point counters. Some people (non hunters) see them and proclaim them 'huge bucks', but not so. Push come to shove, I'll take a doe if things get touchy close to the end of the nine day season. Wish I could take my newly purchased pre war 99R 300 Savage out for them.
