I'm considering a new gun for the upcoming season due to the new lease I was lucky enough to stumble on. It has some nice flat, open fields and I'm looking at some 200+ yard shots. What is your favorite caliber for deer for those 200+ yard shots?

I’m today’s market, look for something with available ammo that won’t break the bank. I’ve shot a 308 for years, and have taken several deer out to 250 yds
