28 Nosler

[wwbrown]

The reamer for the 28 Nosler are available from PT&G they are listed as a standard off the shelf offering along with 30 Nosler (the sweet spot I think), 27 Nosler, and I think 338 Nosler.

 

[jfseaman]

I have a 28 Nosler.

I've been working on variants of the 26 Nosler since before the specifications were published in late 2013.
so far I've built:
27 Nosler
28 Nosler
308/26 Nosler - which is not the same as the published SAMMI spec because Nosler chose to shorten the case by ~.050
338/26 Nosler - which is not the same as the published SAMMI spec because Nosler chose to shorten the case by ~.100

Why Nosler and not Dakota. Simple, standards. The Nosler uses standard magnum bolt face like it grand parent the 404 Jefferies.

The 404 Jefferies begot the RUMs, WSMs, WSSMs and RSUMs.

I used the 338 for hunting. Works fantastic.

These are not designed to be competition chamberings. As has gone the way of 300RUM for 1000 yard, the 308/26-Nosler or 30-Nosler and smaller calibers will never need to go there. The 300WSM and 7mm variants fill that niche very well.

I'm working with a .26 Nosler, shooting two shots and letting it cool to ambient. 100 rounds so far and length to ogive has increased .001, a real barrel burner. : ;D

Wow, chasing the lands will be a full time job.
I think this would be an awesome cartridge for a hunting rifle as long as a guy gets a good load developed before the barrel turns to scrap.

You missed it. Gauging with the Hornady tool will give + or - .001 so in reality, the length hasn't moved since new. This is on a stainless Lilja #3 fluted. Loading 84 of RL33's giving me right at 3500 1/2 minute. Going to do a Brux, same contour and have it nitrided.

Yeah, but try shooting 3 or 5 shot groups. Two shots is not a group, it's a 'pair'. If you can fit 3 rounds in the magazine, then you need to shoot 3 shot groups. Can't call it a 1/2 minute rifle while only shooting 2 shots at a target. It's that magical 3rd shot that goes down range with no barrel cooling in between shots that shows a rifle's true level of accuracy. Only then can you name it's accuracy level. Just like you can't shoot a round of golf by playing only 7 out of 9 holes, then stopping, and say you did great. I'm sure it will shoot 3 shots with the same accuracy, but then you'd have more wear.

However. I believe that the way you are shooting it is the correct way to make a large overbore last in the long run. No sense in wearing it out pre-maturely. I would probably do the same if I had the 26 or 28 Nosler. Instead, I built what would probably be called the 33 Nosler (338 cal) if they ever neck that case up to that size. Using the 375 Ruger case necked down, I get 340 Weatherby performance but it has no belt, 99gr of H2O capacity, and fits in a Rem 700 Mag action with 250gr Berger VLDs. Now that's a long range hammer

Ledd, The mission for this rifle is hunting. I shoot two, let it cool then shoot two more for a four shot group. They are all going in to the same 1/2 moa. I want to know where the first one goes in a cold dirty barrel and where the second one goes shortly thereafter. If all four are in that 1/2 moa, my mission is satisfied. I respectfully disagree that all shots must be shot in rapid succession, especially in a skinny barrel.

I see. Thanks for clarifying. The first cold bore shot is definitely the most important in any hunting rifle. Should make one heck of a long range hunting rifle

Sorry in advance for the hijack.

Hog, question on 7MM Lilja bbl. What is your opinion of it and how many have you used? I had a renowned gunsmith tell me that Lilja 7MM bbls shoot no better than factory remingtons. But he did like the other caliber Lilja bbls. I did not press him on this as I thought that was an odd statement.

Ledd Slinger: What makes that round any different from the 338 Edge or Lapua?

 

[Mr_Happyface]

I wish I had this rather than a LRM, Gunwerk's brass is crap.

 

[Ledd Slinger]

Ledd Slinger: What makes that round any different from the 338 Edge or Lapua?

BIG difference.
1) Short enough to work in a normal Magnum action with a normal Magnum bolt face.

2)Much more efficient. Can push a 250gr bullet at speeds up to 3000 fps from a 26" barrel while burning less than 80 grains with just about any powder you use.

3) Recoil is a lot less. RL17 gives great speeds in the 72gr to 74gr range with a 250gr bullet and does not require a muzzle break to handle the kick.

In summary, you get excellent performance (even when using a shorter barrel), less recoil, and the round can be used by converting most any factory Magnum action. If you have a 338 Winchester in the safe or cabinet, all you need to do is have the chamber reamed out and wallah! You now have a much more powerful 338-375R that gives you nearly as much power as a 338 Lapua.

Got an edge with 30 inch Hart tube on rem 700 long action from Shawn Carlock. Can push 300 grainers to over 2900 with 90gr and 250s well over that and no action mods needed. Not sure most sane men can handle the recoil from 250gr without a brake at that speed though. Sounds like pretty equivalent in 250gr though. May have to consider that when this tube goes south.

I already have a reamer. Only made one barrel with it so far. If you want to build one later on, send me a PM and I can let you use it if you like. I think you'd be really impressed with the bullet speed to recoil ratio.

I don't have any experience with Lilja's 7mms, but do shoot them in .17, .224, 6mm and 6.5mm. All of those shoot comparable to other custom barrels I have used. Don't see why they wouldn't do as well in the 7mms but as others have noted, some barrel makers are at the top of their game with a specific caliber barrel.

While I do like belt-less, the 28 won't do anything that my 7mm Wby will do with book loads out of a 24" barrel.

175's at 3,100 and 150's at 3,300 mv.

In my opinion, belts or no belts, doesnt matter. The best group I ever shot at 100 yards was from a 7mm Rem Mag with 168gr Berger VLDs. Of all the rifles and cartridges I've sent lead downrange with, a belted Magnum still hold my personal title of best group. Measured 0.133" center to center.
But I also get good accuracy from beltless. Never had a case head separation with any of my belted mags when using the shoulder to headspace and case life has always been good. All that matters is if you can make it shoot or not.

On the other note, youre kind of right. Performance wise, the 28 Nosler and 7mm WBY will be similar. But length of the case on your Weatherby is much longer which limits the seating depth possibilities of high BC bullets in a Magnum action. The farther you can seat a bullet out of the case body, the more capacify you have for better performance. The magazine room is the big difference between the two.

Looks like a good start for a .30 cal with 230s.....

 

[Ledd Slinger]

People have necked down the 375 Ruger to just about everything already. From 6.5 to 35 cal. Nosler is just systematically commercializing them with an ever so slight different case design. The Nosler design is only 0.010" longer than the 375 Ruger case, but everything else is basically the same. Both have about 99gr H2O capacity depending on which neck you go with.

The 30 and 338 cal versions with heavier bullets are probably the best for ultra long range performance. The 30 cal 230gr Berger VLDs at high speed would be hard to beat.

Everything else is NOT basically the same.

The 375 Ruger (and wildcats) has a .532 head. The 26 Nosler (and derivatives) has a .550 head and is based on a shortened 300 RUM case (404 Jeffery Based). I imagine that if you tried to form a 26 or 28 Nosler from a 375 Ruger case you may be about to have a bad day (if you're really, really careful and lucky you may get away with it).

The body of the case is about .550" (which is a little wider than the 375 Ruger), but it has a smaller rebated rim. It may be based off 404 case, just like all the Dakota Magnums, but unlike the Dakotas, it uses a standard magnum bolt face. You could say that the Dakota magnums are nearly identical except for the rim. But the 375 Ruger is the next closest thing and uses the same bolt face with the same case capacity.

PS: the key word in my earlier post was "basically"

Not to offend you, but you are wrong. Not sure which case dimension diagram you have read, but the rim is a standard Magnum .532"-.534". The body of the case is about .550" (which is a little wider than the 375 Ruger), but it has a smaller rebated rim. It may be based off 404 case, just like all the Dakota Magnums, but unlike the Dakotas, it uses a standard magnum bolt face.

Do a Google search for 26 Nosler SAAMI case dimensions and you'll see it is what I say. Good talk

PS: the key word in my earlier post was "basically"

I said head, not rim. If you want to consider a case that is .018" smaller at the head and .013 smaller at the shoulder "basically" the same, go ahead, but I doubt that it is good practice.

 

[mshelton]

I may have missed it but is there a cartridge diagram anywhere for the 28 and 30 versions? I'm finally starting to understand the benefit, with the 7 it's STW type performance but that can fit in a magazine, so I'm curious about the 30 and giving what hopefully is 300 Ackley type performance in a shorter cartridge.
