New Cartridge-26 Nosler


#1

.26 Nosler

#2

.300 RUM shortened for standard length actions and necked down to .264?

What’s the intended purpose?


#3

To sell more rifles. I’m sure it will be chambered in one of their new rifles. Nothing like a shoulder -thumping louden-boomer to sell guns.


#4

The old .264 Win Mag never gained the popularity that was predicted for it because it was a barrel burner. The .26 Nosler is more over-bore capacity and inefficient and will eat up barrels even faster. I predict it will be a big success.

#5

That’s the 375 Ruger necked down.

They say that it will be flat up to 415 yards. Well, this must be verified!

In my opinion there already are several .257 and 6.5 mm that are OK for every hunting and shooting conditions for that class of bullet diameter, burning far less powder and being far more gently on barrels.

This number is not too far from top loadings of the oldie 6.5 x 68 mm


#6

Not to knock on Nosler, but I was looking through their “AccuBond Long Range” line of bullets, and they are quoting some exceptional form factors (.93 to as low as .84!). I thought this was odd; there’s no magic to bullet design; these bullets have a similar fineness ratio to projectiles with form factors in the .95-1.05 range, and have tangent ogives of fairly average length for these sorts of bullets, which implies much more average form factors for the projectiles. Are the Nosler numbers accurate? Well, at least one test says “no”. That examination implies a form factor of .99 for the 210gr ABLR, which is much closer to what I’d expect for a bullet of that shape than the stated .86 i7 FF.

I’m not sure how Nosler got their BC numbers for their ABLR line, but I consider them to be dubious. There’s simply no way to cheat and get a much better BC from fundamentally a very average ballistic shape like that.

This wraps back around to the .26 Nosler. Nosler is advertising this cartridge as achieving wonderful performance in part because of the high BCs they claim of their ABLR line.

Ad we can see, no bullet or cartridge in the world can be considered FLAT from 0 to 415 yards.
The smaller and older 264 Winchester magnum with a 123 grains MatchKing bullet has a FLATTER trajectory. I am sure that older European numbers such as the 6.5 x 68 have similar trajectories

Calculated performance with an adjusted BC.

Definitely a 7mm RUM shortenened and necked down. Dimensions at Nosler booth wall are untrue.

So it is a shortned 6.5 mm Ultra Cat


#11

Definitely an RUM variant.
