xausa,
On more than one occasion, I have tripled on deer(Roe)with an o/u combination gun, reloading for the last two. The "trick" is to be far enough away and make sure they( at least the first two) fall in their tracks. A "report", in the distance may make them look, but not run away. If you shoot one, but it runs, they all run. If you shoot one and it falls, the others may look, then start eating again. This is for the end of the season, when you have to fill the shooting plan.
