re: Best deer rifle, caliber, setup for whitetail?

I love these threads.Your .270 is all you need for 300 yard shots good glass and a good trigger are a must.I have killed 2 deer at this range both with a 300 win mag. . The problem is lots of bench time to get good at it . The 300 win mag (with out brake) beat me up..had head aches after range time. I have a new rifle ( and I’ve had many) and it’s a truly fun to shoot and shoot. Flat shooting and low recoil ....6.5 Creedmoor. I’ve yet to see a shooter at 300 yds but I can hug my eye up to scope with out getting hammered and squeeze off a good round.... many calibers will kill at 300yds ..practice is the key
For making that shot when it counts. Good luck.
