I'm an all ranges hunter, and my time is very valuable to me. When I hunt, I aim to be as lethal as possible. I don't award myself prowess points for doing it the hardest ways that I can. I do not take pleasure in wonderful woodland stories of the one that got away. I am there to kill an animal, however and whenever that opportunity presents itself. Yes, I enjoy the hunt, and take satisfaction in winning the game between predator and prey. But, I hunt with this mindset. My sight's job is to make sure my POA is correct.
For that reason I'm a FFP convert. The aspect that drew me to FFP, is the utility. I dial elevation and hold wind (because wind changes, a lot), so wind holds being the same regardless of magnification is a huge plus. When there isn't time or necessity to dial elevation, fixed elevation dimensions are key as well. With this system you have a ruler in front of your face that is the exact same size every time. Change DA because you're hunting in CO? Print a new dope card, the ruler stays the same. Change rifles or cartridges? Light conditions won't let you use max power? One coyote hangs up at 600, the other comes to 100? The system adapts universally.
BDC is a limited system. Operate within those limits and they work great. In the right circumstances, BDC might even be a touch faster than a mil/MOA reticle. As soon as you change those circumstances, the limitations become apparent. SFP is also a limited system. You have two magnification settings for an 800yd shot. And one of those requires extra math and you had to find it for yourself. I don't want a variable power scope with that limitation.
For me, the question comes down to what I'm going to invest in. I want to invest in the system that has the most terminal upside.
