I'm going to start reloading for my 270win, what bullet has the highest ballistic coefficient in this cartridge. I'm leaning towards 140 Barnes X bullet
 
Never mind the BC's it does'nt amount to but 1" + or- at 500yds.
Pick the bullet that shoots most accurately in your rifle. all the magical numbers mean squat if you cant hit what your aiming at.
BTW: highest listed BC's are the 140gr. Barnes(there #'s are inflated) and 150gr. Sierra BT's both in the high .490's
 
If the rifle is used for hunting, the terminal performance of the bullet is far more important than it's BC. In this regard the Barnes TSX is certainly capable. For long range shooting however, you may do better with Nosler's 150 gr. Ballistic Tip. I think the BT's BC is just under .50, and my experience with Ballistic Tips in long range work has been positive.
 
I just want to know the best bullet at long range for deer ,300 to 350 yds, one that would deliver the most enegry
 
All popular deer bullets available in 270 will provide more than enough energy at the ranges you state.
Pick the ones that shoot best in your rifle, and learn to shoot at the ranges you list.
If you have'nt figured it out already, there are no easy fit the peg in this hole answers to this question, every rifle is unique un to its self, and what works in my rifle may not work in your.
Now get off your duff, buy some bullets, and test them and practice, practice, practice.
FWIW: try the standard cup/core bullets first, my favorite being the Hornady SP's, but the Speer Hot cores are good too.
You dont need bonded or poly tipped or special core bullets, were talking deer here, and lets face it they are'nt armour plated.
130gr. Hornady SP's @ 3000fps, sited 2.5" high at 100yds, will strike around 9.25" low at 350yds, while carrying 1440ftlbs of energy.
In laymans terms, out to 350yds you need not hold any higher than a deers back to kill him as dead as dead can be.
 
Bullet Selection

I agree with those that think the Nosler Ballistic Tip slugs are very accurate, and they are, but they are a long way from the best for hunting. I think the jacket is too thin. Plain Jane red box Hornady will be better for hunting bullets. Specialty bullets will be that much better, Nosler Partition, Barnes, or Accubond. IMHO
Carry on!
 
If it will shoot in your rifle, I would take a serious look at the Nosler 140 Gr Accubond. My M700 CDL does around 5/8"(or less) @ 100M with this (three shots), and it is a very effective game bullet as well. Couple of pics attached, while the 140 AB is a 7mm, the performance would probably not be significantly different. Regards, Eagleye.

I would look at the Accubonds. I used standard 130gr Hornady interlocks when I reloaded my newphews 270 WSM, it was loaded light to 270 specs. On two deer both totally blew apart and separated the jacket and core and did not penetrate through the deer on the chest. Only found the jacket in both cases.

I think the Accubonds will do a much better job of holding together, especially if hitting bone and they are still reasonably priced, also highly accurate in everything I tried them in. Yes, they are only deer, but a bullet should not totally dissentigrate when hitting a ribcage. Also there are partitions, Tsx's etc. I have had excellent results using partitions on game. All the money people spend on a hunt, a few extra bucks for quality bullets should not be a factor.
 
The SST bullet works well too! shoots well out to 300y, I shoot Ballistic Tips in my 270 however with almost the same point of aim as the SSt bullet.
The regular SST and the Ballistic tip performed almost the same on Whitetails could not tell the 2 apart. Both were 130 grain slugs pushed by 4350.
I did shoot a bear with a SP bullet 150gr 5 years back or so with good performance. Just could not get the sub MOA performance as i can with a 130g for my 700.

I dunno 2 deer, at what range and at what velocity?
I've shot and have seen shot over the past 20 odd years in excess of 100 deer, and all succumbing to those "sub standard" Hornady SP's. I would guess in excess of 70% of the bullets exited the chest cavity of the deer, and the other 30% were found in varied states of expansion. But I have never seen a total disintegration yet. And most importantly any deer hit in the vicinty of the chest cavity (shoulder to liver) died, as reasonable of death as to conclude they just simply work.
But, like they say your milage may vary.

The range approx 100yards and velocity approx 2900 -2950, loaded light. Yes, the deer died, however, its still poor performance, bullets should not totally blow apart. Twice in the same season. I will pay the extra 10 bucks and buy a better bullet. My point of reloading if for quality and accuracy, not to save 10 dollars. I will not load the interlocks in any of my rounds anymore, though they are fine for range practice. There are just too many better quality bullets out there to pick from.

If is was a less than perfect shot and they were shot in another area, the penatration would be very poor.

The 140gr. Accubond has a BC of .496 which is higher than the Barnes 140gr. TSX (.404). I've shot a couple bucks with the 270win 140gr. Accubonds and they are great deer bullet. A good balance of penetration and expansion for deer. Bigger critters, maybe the TSX would be a better choice. FYI, Barnes list's their new 130gr. TSX (.431) as having a higher BC than their 140gr. (.404)

The Accubonds typically retain between 60-65% of their weight depending on impact velocity and shot placement. This one here retained 65.4% after pounding through the shoulders of a 5pt WT buck. He dropped in his tracks. I shot another buck last year with the AB but it blew right through and I never found it.
