When I started hunting, I only shotgun hunted. Usually it was drives with my brothers, dad, and grandpa, but sometimes we would join in on a larger group that hunted the same land if they needed to hunt the same season as us. I always liked it when the larger group was around because they were from a few hours away and it was the only time of the year I saw most of them. They always had good stories to listen to and there was a lot of laughter. But hunting with them could get nuts with the amount of slugs they would unload on running deer. Over the years, we began doing some sitting along with the drives, and had success both ways. Eventually we lost access to the majority of the ground that we hunted, and our little group became smaller with everyone becoming busier with our own lives. For a number of years I would hunt with only one brother and sometimes my grandpa and try to do drives, but that left a lot of escape routes uncovered and we would end up just spooking deer off the farms. I enjoy sitting as much, if not more, than trying to walk a farm, and I had to work at getting my brother into that mentality. However, we have since pretty much converted over to stand/blind hunting for shotgun as we figured it wasn't doing much good to bump the deer to the neighboring properties. If we did a "drive" it was basically just still hunting through slowly, trying to bump deer to each other. It's been several years now that we've hunted together as we now usually hunt different seasons, so now we both pretty much just go sit on our own. However, I will sometimes still hunt through parts of the farm if I'm not seeing much activity on sits or toward the end of the season. I've hunted with another group a couple times in the last few years for something different and to add a body. I still do enjoy a group for the stories, laughter, and fun. But there were a couple things I saw go on that I didn't care for and I'd prefer just to go hunt by myself. I'd probably still go with a couple guys to do slow "drives", and who knows, maybe I'll go with a larger group again if I get that urge.
As far as being successful on shooting more mature deer, I think you have to have some management practices in place. Whether it's on your ground, or a neighboring piece and hoping to get them when they venture over, management has to be there. You can't shoot everything that moves and expect to have mature deer. True, some will make it through year after year, but the likelihood goes down with more pressure. In my area a lot of the ground has been bought up for hunting in large tracts that don't allow drives. There are smaller tracts, but if they are for hunting as well, I'm guessing the owners have the same thing in mind: big bucks. There has definitely been a shift to more food plots and less movement of the deer from farm to farm. Thus most of the neighboring ground becomes a sanctuary and the reason we don't push deer as much any more. Sometimes I would love it if those neighboring pieces got pushed once in a while, but I suppose that is more for me maybe getting a chance at what's across the fence. That being said, I fully understand that what we do on our side affects our chances as well, and that's why we've pretty much converted to stand/blind hunting with the occasional still hunt through. And I don't blame the neighbors for owning larger tracts and hunting the way they want to. I'd probably do it too if money wasn't a factor.
