I dropped off a Krieger 1-7.5 .277, action and a McM Hunters EDGE to my smith yesterday. It’s CRS’s fault  Like Chad, I have and have used 270’s and love them. Bullets like the 155 LRX and 165 Nosler ABLR are sorta what I wanna focus on.

Badlands look pretty good. Not tried them yet. I have 1-8 twist so probably go 140s though I think the guy said 1-8 ok.
Riflehunter
Plenty of good high bc hunting 270 bullets now. Pretty much every manufacturer offer heavy 277 bullets in their hunting lines now but Hornady. True 7mms and 6.5
Have more high bc match bullets. Some folks like them and more power to them. Personally I would not risk a “once in a lifetime” hunt with a bullet that is not designed for hunting even if little higher bc

I have lived with 270s since 19668. I have shot the throat out of 2 barrels and am working hard on a 3rd in one rifle, and have shot several thousands of round through about 7 other rifles.
With all that said I have never found any problems at all with the regular 1-10" twist. If some company was to make 185 or 190 grain 270 bullets there may be a reason for a faster twist. But for what I have used my 270s for up to and including killing horses and cattle on our ranch, I have never seen a problem with 1-10. I have thought about the use of a super long bullet, but the concept is a situation that is so specialized as to slip more into the "what-if fantasy land". It's as if the world wants to ignore the near century of excellent results we've seen from the 270 with 150 grain bullets and find some 'idea" of how it needs to be better.
There are times I want more. In those times I use a 300 mag, or even a 375H&H. I simply can't see a need or even a want for a 270 with a longer heavier bullet. Speer made 170 grain RN bullets years ago and I used some of them and I am very much a fan of the Nosler 150 and 160 grain Partitions as well as the 150 grain bonded core bullets.
To each his own. If someone wants to play with a 270 with very long bullets, so be it. It might be fun. But from results in the field on game killed over 50 years, I have serious doubts that there will be any meaningful gains. My thoughts exactly. If I want 160grs or 175grs I’ve got 7mm rifles for those.

The .270 may have been about the best tool around for deer size game for 90 years with 130's, 140's and 150's but other calibers on either side now have similar weight bullets that perform slightly better at longer distances because of their bc. For example looking at what Sierra offers in hunting bullets, their 140 TGK 6.5mm has a bc of .563, their 7mm TGK 140 grain has a bc of .545 but their .270 140 TGK has a bc of .508. Surely it's not much to ask for a slight improvement in middle-weight (e.g. 130, 135, 140 grain) .270 bullets so they have comparable bc's. If they made some 140's that work in an 8 twist that have a bc around .550-.560, then that would be better. As it is, there is only one bullet in .270 at 140 grains that has a very good bc- the Badlands SuperBulldozer at .650 and that's a long mono. It doesn't make sense to have bullets that have more wind-drift, more drop and less impact velocity unless you're always shooting at close range.

Seems like it’d just be a lot easier to just use a 280 or 6.5 if long range shooting is what you like doing.

Even at 350 yards, middle-weight bullets with high bc's show an advantage over poor bc middle-weight bullets.

Lou Exactly, the farthest I have shot an animal is 475 yards. Long range hunting does not apply to me. I am a 270 looney, nothing more, nothing less. If I was to start competitive shooting I would re-evalute. But for my needs, I am set. I stretch my my rifles out to 1000 on our property. But am not too serious about it, nor successful. Out to 600, watch out. Even though I never plan to shoot at a critter that far. This new rifle is going get some serious LR work, just to see if I can.

General info for those shopping barrels. My preference for barrels, especially their prefit for Remington 700 and Savage Target Actions is the PacNor Super-Match using the PacNor barrel nut, and polygonal rifling. In the .204, .224, .6mm, and .308 these barrels are the most consistent and accurate I have installed. They also foul less than others and clean easily using only solvent and patches. Just a suggestion for consideration.

The 155 LRX will drift around 2" less than a 129 LRX at 500 yards in my typical hunting conditions, when launched at speeds that temperature stable powders are capable of sending them (i.e. not Reloader 26). A 129 LRX will already bust through elk shoulders and exit, and both reach that 500 yard distance with enough speed to open, so not sure what all there is to gain from a practical perspective, but building new rifles is always fun!

I have an extra 1-9” Benchmark .277 #1 if someone needs one

Exactly, I have 129 LRX's on the bench too. Along with 130gr TSX, TTSX, and CX's. Might be some 110gr TSX, TTSX, and 100gr CX's if I really want to speed things up.

It cracks me up, I think some folks think you have to use the longer, heavier bullets just because you have some extra twist. 6.5's have had 7 or 8 twists for years and folks have shot everything out of them from light stuff up to the most aero bullets they can cram in them and that's cool. Add some extra twist to a 270 and it's like it'll be hamstrung to one or two bullets..

Yep. If I were to build a 270, it would likely be an 8 twist or faster. Not like I'd be worried about nuking light jacketed varmint bullets, as I've rifles better suited to those pursuits.
More pointing out that the current .277 bullets available for faster twist don't gain much over more common bullets at 270 Win speeds. Like the 170 Ballistic Tip - the BC doesn't make up for the lower speeds. Regarding some of the other choices....I don't know about you guys, but I've not had the best of luck with boutique bullet dealers, so tend to stay away from them until they've been around long enough to establish themselves as a viable business (remember Wildcat bullets?), and let someone else do the beta testing performance on game.

For sure PG, I’m okay with what Barnes, Nosler, Sierra, Hammer and some others make and to be honest I’m not likely to shoot 10 different bullets out of it, more than likely I’ll find one I like that works for me in regards to hunting and use that.
I have a big stash of the old 130 and 150 grain Bitterroots and I have a good feeling the extra twist won’t hurt with how they perform there either with extra RPMs.
But I guess I’m in the camp that since I’m putting a new barrel on the rifle the extra twist won’t hurt anything and opens doors if I’d like to try a heavier bullet as well. Your comparison of 2” at 500 yards between the two makes a ton of sense and since I am a dialer with most stuff over about 250 yards I’ll take the little extra if everything else makes sense as far as wind drift is concerned.

PG, I understand exactly where you are coming from. This is not about pragmatism at all. I have shot thousands and thousands of rounds through all my 270's. I could easily live with a 130gr mono seated over 60gr of H4831 for the rest of my hunting. Or a 150gr Hornady Interlock, or partition or..... Looney is as looney does.  I have one rifle that shoots the 145gr ELD-X into tiny groups way out there. Will the boutique Badlands precision bullets be significantly better? I do not know, but will have fun exploring it. My ultimate goal is not a one rifle/bullet combination that does it all. It is to have fun, try different things. But I needed a barrel and I thought why not go faster twist. I am not so much about the long range high BC bullets as I am about the heavier bullets at this time. I will certainly stretch them out. Heavy for caliber bullets have performed for a hundred years. Monos have changed the game a bunch and are my preferred any more. I am also of the opinion that a faster twist helps monos work better. When I built my last three 338-06's I went with a 1:9 instead of the standard 1:10. The extra twist has not been a detriment at all, near as I can tell. Especially with 210gr monos I like to use.

I started shoot faster twists around 1988 in 27, 28, and 375. The only way to get one was from a cut rifling mfg. With the bullets then available I had best results with 1-9 in the 27 & 28. I found the 1-8 to be a little fussy with the lighter weight bullets (130-150) compared to the 1-8. I tried several different 1-8’s and they didn’t stay around for long.
In the 375 I used 1-12 and 1-10, which I preferred. In 375 1-8 and 1-9 were not great. I you gave me a 1-14 I would immediately change the barrel.
Today bullet quality is better. If a bullet is slightly unbalanced a fast twist will really give poor results. The Juneke machine has improved core and jacket quality.
Like most everything I concluded one is best served by a balanced approach.
Terminal performance is really changed by faster twist. The tin foil jackets will really come apart.

Here is my new 1:8 twist 270 WCF with initial range report. New 270 WCF hunting rifle with 1:8 twist RinB, I do not foresee any issues with tin foil bullets in my new rifle, it will get fed a steady diet of monos or lead core bullets designed for the faster twist.

I have been using Proof pre-fit barrels for my DIY builds and I'm looking to build another 270 but they don't offer pre-fits for the 270, only carbon blanks. I found their twist offerings interesting, ideally, I'd go with 1:9 but they offer 1:7.5, 1:8.4 and the traditional 1:10. I guess I'd go with the 1:8.4 if I went the Proof route.
