The NEW KING of the 270 Calibers

Biggest limitation I see is a lack of quality vld (and heavier) bullets in this calibre.

This is what will kill this One pretty fast. This is gonna be a marketing flop. The 6.5, 7mm and 30 Cals hVe way more advanced long range range projectiles.

I dunno, this is my local shop’s shelf on Wednesday. The 150 has a G1 BC of .591 / G7 .298, and they’re bringing out a 165gr todbartell says that will doubtless smoke those numbers. Even the modern 130s and 140s are very good for BC. I’m not jumping on the bandwagon of any of the Noslers yet but I can readily admit I’d have no trouble feeding a .27 Nosler high BC bullets. I actually think this round’s niche would be at 110-130 and screaming velocities sighted in for zero at 300+, could potentially have a 0-400 yard rifle with no holdovers.

The standard 270 Winchester is 1095.2 in the red part of the over bore chart...

7mm Remington Mag is 1326.0,,, so the hot 270 will burn out the barrel pretty fast one would think...

It might be pretty close to the 22 Cheetah in Over Bore... 1500.0 +++ on the chart would be nasty for barrel wear...

If you’re going to reload it with the fanciest high BC bullets you can get, I don’t see why you wouldn’t just go with the 28.
 
I agree with Ardent, there's enough bullets for the 277 cal, I believe burger has new bullet, i can't remember the weight but think its in 170-180 gr weight.

170gr 277cal EOL. SD of 0.317 and g1/g7 BC's of 0.676/0.335 (2500-3000fps)

Mind you, the 195gr 7mm EOL has SD of 0.345 and BC's of 0.777/0.385.

The 270 cal is great for throwing light bullets fast. I don't see the point in loading it heavy, from a hunting perspective if I want more weight I probably want more diameter too.
 
What will this cartridge kill that the 26 Nosler and 28 Nosler won't....Right, nothing.

But for the cost of some cheap tooling they can dip into the wallets of a bunch of .270 fans. The .270 is light recoiling, but a lighter wallet increases felt recoil... so it's a wash.

They should just do every calibre from .24 to .46 and get it over with... :)
 
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.

It will throw heavy for cal bullets just as well as any other cal if it has the right twist rate. For hunting I prefer 110gr to 150gr bullets in 277 just like if I was hunting with a 7mm 120gr to 160.

This is a good post.
