"Best" rifle kill, Trans Pecos mule deer from shooting rail in high rack truck, 548 yds (verified with lazer range finder), Win Model 70 in 270 with Leupold 2-7 scope. Hold over. Happened in about 2005 or so. I had been shooting that rifle since I was a kid, many many round down range at targets and game learning the exact hold overs.
Best "modern" rifle kill was NM antelope at 440 yds, custom 7 Sherman Short/NF NXS 5.5-22 off tripod with arca rail. Happened last year. Almost seemed too easy.
I regularly shoot steel to 700 yds with my hunting rifles, but also have two dedicated range rifles in 260 and 308. Bang a lot of steel at all yardages out to 700 (private range) and always practice dialing/shooting off the reticle as well as the turrets.
