Re: long range accuracy?
As far a shooting and killing an animal at that distance, everything changes. You won't be at your shooting range anymore, and altitude will be different, wind will be needed to be calculated correctly, spin drift, coriolis effect has to be understood and accounted for. These shots should be practised, and practised again. And when you think you got it , practise some more. YouTube makes it look easy , but there is so much preparation that goes into a single shot at that range. Especially cold bore. I think 1/2 -3/4 inch off the bench at 100 should be your benchmark. Welcome to long range shooting!
