And the 270 and 7mm Weatherby's. Too often forgotten or omitted, but seldom beat.Choices are endless.
If Weatherby is a thought.
257 and 6.5/300.
I shot a small deer at 25 feet one time. Hit him right in the throat patch as it faced me with a 147ELDM. Dropped it, of course.I can't/won't argue with that at all.
I'm much more concerned with the use of .22 caliber, highly frangible bullets @ high velocity……which some folks insist upon using! memtb
One thought I had when I read this is that at at 8.33 yards that long bullet may not have fully stabilized when it hit. I shoot 6.5 eldm's in 123 and 147 and 168s in 308. I will be the first to admit that short range high velocity shots are not their strong suit. I like them better at distance. I certainly can't explain the skull shot.I shot a small deer at 25 feet one time. Hit him right in the throat patch as it faced me with a 147ELDM. Dropped it, of course.
Climbed the bank and was shocked to see the bullet had blown all the hide n meat off the front side exposing the spine but did not exit or even break the neck!
I believe shrapnel to the spinal cord killed it or it jus bled out as i was climbing up that steep slippery clay bank.
Muzzle velocity was lil over 2800 which is a far cry from 3300.
Same bullet shot another buck in the head at 92 yds same trip n it went thru n thru n didnt shatter the skull. I dont like to do that but everything else was behind limbs.
Ive killed many deer with much smaller n lighter and frangible bullets and have never had one fail to break the neck on a hit like that.
Rainy day story telling with no particular point over. Lol
Good point about the stabilization. Barrel is a 7 twist for whatever thats worth. I never worried about the blow up honestly, like Id still hunt with em in a area where I could. I wouldnt put it into large bone at super close ranges but i dont do that anyway other than neck shots.One thought I had when I read this is that at at 8.33 yards that long bullet may not have fully stabilized when it hit. ..
I shoot a whole lot of deer and hogs every year because of a unique set of circumstances. .. He said many had just dropped but some made it 20 yards or so. He shoots behind the shoulder shots. So I asked what bullet he was using. SURPRISE, 55 grain Vmax's. ...But I strongly believe his choice is going to bite him in the butt and most likely sooner than later.
This last paragraph about my friend isn't necessarily replying to your post. It's just more rainy day storytelling and food for thought.
I once shot a spike elk walking unaware, broadside behind the shoulder with a 220 gr. silvertip from my 325wsm. It took 2 steps and fell over dead. I was surprised to see 2 exit holes in the offside ribcage. It seemed that the bullet separated, but could have been bone. I've never used those bullets at that velocity since. I try to use premium bullets for any hunting other than varmints. (Still 308 for deer.)Many years ago I had a 270 Winchester 130 ballistic silvertip do about the same thing as your 8 yard shot. But mine was at a much longer range of 18 yards. Killed the deer dead but did not break the spine.
