The NEW KING of the 270 Calibers

not as overbore as CGN's beloved 257 Wby

Apples to apples, this 27 Nosler will give a solid 125 fps edge over a 270 Wby Mag, 175 fps over a 270wsm, and 325 fps over a 270 Winchester

For open country hunters who love the romance of the 277 diameter, this is worthy of a look

The strength of .277s isn’t in the high BC department in my eyes though the bullets certainly exist now, but in the light end for fast and flat. It’s handy though that high BC 150gr+ stuff is arriving on the scene making .277 one of the most versatile bores a mountain hunter can have in the cabinet. The 110gr Accubond has a G1 BC or .370 which is nothing to scoff at, and if it can be launched from this case at 3850 as rough math would indicate that makes this rifle 0-400 yards point blank when zero’d at 350. That’s useful to any sheep or goat hunter. Often it seems folks think heavier is the way and it’s often counterproductive, I’ve learned in outfitting that trajectory is the single biggest variable in a shot and the hardest to compensate for in rapid and short lived shot opportunities. 400 is as far as I’d like to see a practiced and non-expert client shoot, and to be able to do that with no concerns except wind really is a game changer. There are a couple existing rounds that will do this presently, even the .270 Win does a great job at 110gr though it tops out 50 yards shorter for point blank, but I don’t see the harm in another option.

Well said, couldn’t agree more on the trajectory statement. it’s unfortunate there are so many members here who just repeat what the last one said instead of critically looking and actually discussing a cartridges pros and cons, nope grown men posting silly pictures and parroting opinions. You really start to notice a pattern of most of the posters on this thread, seems to play out on a lot of threads are line here. Too many parroting sticks in the mud

Back in the mid 80's, when i was culling goats and meat hunting deer, One of the cheapest ammo options, that shot well in my old 700 .270 win Mountain rifle, was PMC/PMP 110 gr soft point, very effective, any animal shot, pretty much expired on the spot, and smaller game, like goats and chamois, would sometimes be torn up so bad, as to be worthless for meat. pretty much point and shoot, out to as far as I felt worth while, with an old four power scope, if I thought it was to far, duplex level with the animal's back.
I remember getting onto a mob of goats, in a creek head, in the pine block, we had to cull out, and shooting 63 in one barrage, rifle was so hot i had to run down and dunk it in the creek, reload and kept banging away, those 110 gr soft points where perfect for that kind work.

I have to agree with this^^^^^^^^^^. I have a 270WSM 24.4" barrel and love it 150gr 3100fps+, I find the 27 Nosler interesting.
 
If more is truly better, just neck down a 30-378 to .270 and call it a day. If you object to the belt, neck down a .338 Lapua.

In the meantime, the old .270 Winchester is relatively inexpensive and easy to load for and can be had in light, portable, accurate rifles, that seem to kill North American big game with boring regularity; even though I'm not much of a .270 fan.
 
There comes a time when a caliber just needs more bullet weight to truly be more effective - and that is where the .270 just bites it for me. Get the .270 up into the 150 grain bullet weight range and try to make it go fast, then you are better off just going with a larger magnum caliber such as just about any 7mm mag - or better yet a .300 mag of some sort. Better bullet selection too.

That sounds like a hell of an adventure. I have a good friend that was a govt hunter in the 1960s and he has some great stories. Showed me a really neat limited release book with tons of pictures in it, the name escapes me. That job would have been right up my alley!

27-Nosler-Mic-Drop-ad-8.5x11-2.jpg


No caliber is more uniquely American than the 270. For over 90 years, American hunters have taken to the field in pursuit of nearly all the game the lower 48 states have to offer with a trusty 270 in hand. Over the decades, millions of deer, elk, sheep, bears and pronghorn have fallen to it, to grace the tables and walls of America’s hunters and add chapters to the American hunting lore. For 2020, Nosler has chosen to take the venerable 270 caliber to a new level with the introduction of the all-new 27 Nosler. Conceived as a 21st century upgrade, the 27 Nosler delivers previously unobtainable downrange ballistics by pairing the ultimate combination of case capacity with modern long-for-caliber bullets.

The result is a standard setting offering from Nosler that redefines performance as radically now as the 270 Winchester did upon its introduction in 1925. If you hunt where the game is tough, the shots are long and demanding, and there is no room for compromise, there is no better choice than the 27 Nosler.


27+Nosler+Cartidge.jpg


Twist Rate 1:8.5” The 27 Nosler’s faster-than-standard twist barrel is designed to stabilize modern, long range bullets.

Case Design: Based on the 404 Jeffrey Same case as the 30 Nosler When compared to the 28 Nosler, the 27 Nosler has a longer neck and a shorter length to the shoulder to prevent the 28 from being chambered in the 27.

The 27 Nosler has a long leade for sleek, high BC, long ogive, ABLR and RDF style bullets.

Fully prepped, Nosler premium cartridge brass in 27 Nosler will be available in 25ct boxes. If needed, 27 Nosler brass can be formed from 30 Nosler brass. 30 Nosler cases are preferred if forming 27 Nosler cases because of the similar shoulder dimension.

Case Capacity: Fireformed case, overflowing to the neck = 98.4 gr/H2O with a 150 AB seated to 3.340” OAL = 89.9 gr/H2O

Performance

Comparison Velocity: Loaded with a 150gr bullet, the 27 Nosler is 400fps faster than a 270 Win, and 300fps faster than a 270 WSM at the muzzle.

Energy: Loaded with a 150gr bullet, the 27 Nosler has an additional 800ft/lbs. of energy over the 270 Win and 600ft./lbs. more than the 270 WSM at the muzzle.

Trajectory: At 500 yds. the 27 Nosler drops 11” less than a 270 Win and 7” less than a 270 WSM.

I get 3150fps out of my 270WSM with 150gr. so that means the 27 Nosler does 3450fps interesting.
 
My perfect .270 would be the .270 Roberts- a .257 Roberts necked up with no changes. Which also means I've just reinvented the 7mm Mauser, but with an oddball bullet size instead of the more common .284"

I really need to win the lottery and make this happen.
