As P.O. said, up to a point more powder equals more velocity.

I find the sudden love for the 270 amusing. I forsee more orphan cartridges to join the SAUMs, WSMs, 325, 307, 356 and so on.

When someone can tell me what any of these "new" 270s can do that cannot be equalled by the boring old 7mm RemMag IN REAL WORLD PRACTICAL HUNTING SITUATIONS I'll listen.
The same argument or approach could be taken with pretty much any cartridge. A fast twist 270 pushing a 170 class high BC bullet has real potential. This thread wasn't about a 270 vs 7 RM. 🤠

Yep, ordering a 26" 1:8 twist and longer throat as result. The .270 Win offers a lot benefits in faster twist and higher BC bullets for those who like the caliber. If you don't like the .270 Win, nothing will change that. I see the .270 twist change no different that what has happened to the 300WM. Faster twist now on factory rifles for the heavyweights. The .270 Win brass is easily found, cheap, great neck for longer bullets, good velocity with newer powders like RL26. Recoil for some is always a decision but it is nicer than most. The COAL needed may require some magazine changes but that is no different than what we did for the 300WM to accommodate the longer heavier bullets. I ran a ladder with a 24" barrel and was surprised by results but since have confirmed to be normal for the powder and bullets. All the different caliber suggestions instead are nice but if you like the .270 this ups the game for it. Is it a .270 WSM? No but never meant to be and still provides a nice niche for shooters. Maybe we should call it .270CM to satisfy the need for a new glitzy caliber name?

"The 170 EOL topped out at 3067 with very slight ejector that was hard to see but I felt good enough. The 165 Matrix was 3079 but No Pressure. Did not run ladder deep enough since I was surprised by load."

Good words of wisdom from the creator of the magical 270 Thor's Hammer. 😎 Right with you bud.

Anyone re-barrel a 270 Win to a faster twist for the heavy for caliber bullets? I'm looking for real world velocities with let's say 165 gr Nosler LR Accubonds or other heavies. I see the new 6.8 Western is advertising factory ammo at 2970 fps for the 165 LR Accubond and am curious how much speed is gained with the Western over a fast twist 270 Win. Thank you.
I am a bit late in the game, but yes, I have a .270 AI with a 30" Lilja SS barrel 3G 1:8" + JP Enterprise Beenie Coulee MB especially built to propel the 165/175 Matrix VLDs. My current accuracy load for the 175 Matrix is 2993 FPS with H4831SC. If I do my part, it is <.75 MOA at 1KY, I have reached near 3100 FPS, but the group opened up and showing pressure signs. Others are claiming ~100 FPS gain with RL26.

Berger shows the .270 Win giving 2899fps with the 170gr EOL with R26 and 2868 with 7828ssc. That puts the .270 Win right there with the western.

Though I don’t have one right now, I love the .270 and always have. I’ve had more DRT kills with it than any other cartridge I’ve ever had. I’m very tempted to build a fast twist .270 just to get the haters all twisted up like the Creedmoor haters do.😂😂

My love of the 270 caliber happened back in 1986 with this really dusty, Savage 110 rifle on the wall for $125.00. It was chambered in 270 Win. I never really was in love with the 7MM, honestly I hated the dang thing from the minute I read about it. I knew little about the 270 win except that I had read lots of people/gun writers hating on it and some singing it's praises. I am not a main stream caliber guy so I like the odd ball calibers. 270 Win turned out to be very accurate, extremely deadly to deer, pronghorn, and it exploded ground squirrels. the 7MM R/M is a magnum class case. the 270 Win is not, the only drawback to the 30-06 based case until you neck it down to 257 caliber. that went away when some really great wildcatter put the 270 slug in a 264 W/M-7MM R/M case. then the 270 and the 7MM became equals. In the gun I had made up in Montana that wildcat was more accurate than any of the 7MM R/M cult's guns could offer up. the deadliness of the 270 versus the 7MM is negligible in actuality. the slugs are 0.007" difference. Not much at all. the 7MM was hyped by the gun writers for a huge payday for the writers. it gave the 7MM more exposure than the 270. this same thing happened between the 243 win and the 244 Rem (now the 6MM Remington). One big mistake Remington did was they did not offer the 244/6MM in a 1:8" or 1:7" twist barrel that would have made it far superior to the 243 whom did offer their cartridge in a heavy twist.
I really fell in love with the caliber once I found piles of it on the shelf at the sportsman's in Rocklin, CA. I found it all over the place.. 7MM R/M, 30-06, 308 win, 30-30, and 243 win were all out but 270 was plentiful.
Now with the resurgence of the 270 caliber; the bullet manufacturers are making longer, heavier, better slugs to compete and in some cases exceed the 7MM bullets. now we, the 270 crowd, have a fighting chance to make the 7MM as obsolete as the 7MM made the 270 back in the 1980's, 1990's, and up to 2015. I might get to be the "trendy guy" on the block for being a 270 fan for the last 35 years.
Other than that, 270 and 7MM are virtually identical in most every way; lethality, stopping, down range kinetic energy, and BC are all very comparable. My suggestion is you love the 7MM, stick with it. If you are open to a reviving an old very maligned caliber, then try the 270.
BTW, I built that 270-264 Win Mag up in Montana as a huge middle finger to the guys regurgitating the line, "the 7MM R/M is the only caliber that will take down deer, pronghorn, elk, and bear effectively." Which we all know is utter horse manure. My go to gun for Deer and Elk was my 270-264 Win Mag or my 270 Winchester. my go to gun for Moose is my 338 Win Mag. My go to gun for Bear is my 375 H&H. I do not use an inferior caliber to do the job. I go out with something I trust to do the job. I have seen a guy with a 7MM R/M take 7 rounds to put down a rather tough inland brown bear. that is too many shots. The guy nearly died on that mountain. If I had not put one or two rounds of Hornady DGX out of my 375 H&H that guy would have been dead.
In all honesty; 7MM does not work for me. It never has, it never will. If it works for you then I am happy for you. Like I said with the new advances in 270 slugs with more selection, more weights, and more development, the 270 and the 7MM are so close to being equals it really does not matter which one you have. all that matters is bullet selection and shot placement.

Sorry Y'all. this got away from me.
No problem on your 7 mag hate; your LONG titrade is a different story.
I’ve shot a 7mm Rem mag 160gr partition for 30+ years and have 20+ one-shot elk kills with it. My .270 is a great deer rifle, but after having to take two shots for elk, I stopped using it for elk. I now have the time and I’m building a 6.8W 1:8” twist to go with the 7mm I built recently with a Bartlein gain twist barrel.
