Very true and The worst part is I know betterNot wise to shoot MK248 mod 1 ammo in guns not chambered for it. Its loaded for 68k psi in their chamber. You probably hit 75-80k.

Yes, you are looking for a load whose POI is always the same, even if it varies by X amount of powder, that is, with more/less pressure-speed.OCW?

That allows this method. From my experience it appears that with an X charge that works well on a 308win rifle for example, it also works well on a similar rifle. Just by minimally adjusting CBTO, the load allows very similar results. I am not saying that one load is ideal for ALL brands and models of rifles, I am saying that it must be a method that ammo manufacturers use, so that it works well in all.
Do you know the OCW method?

I work in aviation so acronym soup I am use to but have never seen this one. I have read Lee's theory on volume loads vs. weighing loads (in the Lee Manual; not a fan personally). As well as finding the correct node for your barrel based on varying powder charges. The one I personally use is the Berger seating depth method https://bergerbullets.com/how-do-you-load-and-tune-a-vld-bullet/followed by the powder node method.

Nosler data is cool in that it shows you several powders they used and their most accurate load...for that cartridge and bullet weight. I believe the barrel length is there too. So for retail ammo loaders they gotta be using a set up that mimics the rifle that the customer has in his hand. Then there is hunt loads and target loads. And, probably a bunch more. And I bet their recipe changes with the times. I bet they experiment with duplex loads. There's a bunch of different ways to bake that bread.
No, that info is for reloaders. Nosler does not reveal its factory loads and recipes.
