Put a good expanding 140 class 6.5 bullet in the vitals at a minimum of 1800FPS/1000FP, (range equivalent) in a whitetail and you should have a very high probability, dead deer. IMO
I will add one more thought, if you are going to be shooting past 350 yards I strongly recommend a partner as a spotter to see what the game does after hit and where it goes and drops. Across a small canyon in brushy country, it's a big deal recovering game.
M X V = momentum energy is M X (VxV)Adam
isn't Energy, = mass x velocity. Y can't energy into the boiler room be a good indicator of humanely dispatching an animal?
Well, it happened. And the 'lope got on someone else's property and disappeared. It went about 500 yards and crossed a fence, and over a rise. I watched the shot hit through a 6X18 power scope, and saw the ribcage dimple from the impact. But I had to blood trail a Whitetail one time when a friend hit it with a double lung shot, and it went around 150 yards before we could shoot it again. It had bedded and tried to run. That was a 30-06 with 165 grain bullets, and he dropped a doe with it the next day at 305 yards on the spot. Some animals are like superman part of the time. By the way, I've been hunting and killing various animals since I was 16 years old, and that was 53 years ago. Give it enough time, and you'll run into super antelope/deer. I'll bet there are a number of people on this forum who have done so more than a few times. That's why I would limit my shots with what is a small to medium caliber rifle to 400yds or less. I wouldn't try for deer past 400 yards with my 25-06 either. It will do it most of the time, but when it kills but not right now, I then have to hunt through some rough country to find my animal.So I have a decades of experience with the 270 140gr cup&core bullets on coues whitetail and they have all dropped hard at ranges from 220y-300y. I have a difficult time imagining lopes not going down to a 6.5 130/140 bullet at 200 yards. Being as how the 270 cup and core 140 grainer at 300y can't be that different from a 6.5 bullet at 200y.
Well, I have the same 6.5 Tikka, this year I hunted also with both the LR Accubond 129 grain as well as the ELD-X 143 grain.I've spent the past couple days browsing forums on this very topic. Based off what I read 500-600 yards is going to be the max distance many would feel the 6.5 Creedmoor with the proper bullet can reliably take down a whitetail.
I just got a Tikka T3x in 6.5 with a Leupold Mark5 HD 3.6-18X44 scope. I am going to try 3 different factory loads: Federal Terminal Ascent 130 grain, Nosler Accubond Long Range 129 grain and Hornady Precision Hunter 143 grain ELD-X. All three are softer construction designed to expand at long range.
With the proper bullet for long range terminal performance, what do you folks think the max lethal range a 6.5 Creedmoor could be on whitetail?
