What’s the farthest distance you’ve shot a deer at and what’s the longest range you’re comfortable shooting at?

I shot this doe this afternoon at 275 which is about as far as I’m able to shoot at my farm due to topography, field layouts, and timber. I have a 30-06 that I used for this that, with its optic setup, I’m not sure I’d be comfortable much further past this. I have a 7mm Mag that I think that I’d be comfortable out to around 500 on a deer (shot one at 350 in Texas a few years back). I’ve shot targets with this rifle out to ~850 but I don’t think I’d want to try that on a live animal.
