338-30 Nosler

I’m building a 338-30 Nosler for a future elk hunt and am looking for a starting point for loads. I have 285 eldx to start with, I remember someone out there with a 338-375 ruger which is pretty similar. Thanks
 
Isnt that identical to the 33 nosler? Nosler has data for 265 and 300 grain bullets. Could probably extrapolate

It will have near identical case capacity as a 340 Weatherby. I would start there.

No. It is not. The 30 case is larger.

Check a few various case capacity lists for the .340 WBY, it's a toss up in my opinion:

1 list = 98 grains of H2O
2 list = 99 grains of H2O
3 list = 100 grains of H2O

33 Nosler is listed as 96 grains of H2O

30 Nosler is listed as 99 grains of H2O

Yes, the 30 Nosler has 3 grains more capacity, count them 3 grains.

The question I have though is what is the seating depth you've chosen to start this process. That 285 ELD-X will need a 4" box to feed that bullet seated out. The data charts all call for a seating depth of 3.340" established when we shot all the more common weight .338 bullets like the 250 grain or lighter cup and core. The 285 suggested is 1.743" long according to the JBM bullet list which will eat up a significant amount of powder capacity when seated at 3.340" for the book loads. That's a loss of 19 grains of powder space with that bullet seated 0.938" deep.

Your choice of course but I bears some scrutiny.

I personally skipped this section of wildcats and went with the .338 Norma Mag. Yes, it needs a slightly bigger action but any that fit the Lapua will be great. There's none of this screwing around. And I'm a dedicated wildcatter.

Look it over again, please.

This is set up with a dbm by Hawkins
There is clearance in front of the bullet with not taking up powder capacity
 
I have had a 33-28 Nosler for a while now. It is a larger case than the 30 Nosler. I measured 103 grains of water. H-1000/85.5 gives me just under 2900 fps with Accubond 250s. This fits very will in a CRF M-70 with a 3.6" magazine box. I am using a RUM box and follower.
