I have a question...,
Since they look like pretty good groups, and you're still breaking in the barrel AND working up a hand-load for that barrel, with you going after whitetail you should be good. So..., the question is, which bullet would
also work well..., on you your next likely choice for game? Is there any favorite for your second, most likely quarry?? You're working up a load, and if all three of the bullets are fine for whitetails then why not work the load for additional game and THUS when you're settled on the right recipe..., you're good to go for just about anything that you want to harvest. That way you don't need to work up an additional load for another game animal, and if you get a phone call on a Thursday night akin to: "Hey I got a sweet deal on [fill in animal name] hunting this Saturday and I want you to join me!" You won't have time to work up another load, BUT because you already thought of that..., you won't have any worries about your hunting load.
