All the information you need to unleash your potential and your equipments' potential is there. Specifically, I opened all the "Lets Make A Deal" doors and revealed a projectile in a factory rifle using a factory 338 chambering and barrel that is capable of this level of performance..... Just as I did last year about the information on the .30 caliber 180 grain Hats. Factory chamberings in factory rifles and high levels of performance. That is the message!
How you use it for your benefit is up to you. It does not matter how my equipment functions as long as it can prove and represent what can be done. Your equipment is probably different than mine and it would be unwise to get locked into my powder, powder charge, cases, primers, barrels etc. I do recommend getting some of the bullets and follow the directions on the invoice and apply them to your equipment and have some fun.
Seating depth is -.015" from land engagement of the ogive to the barrel lands as previously mentioned. If you don't have an ogive tool, you need to get one... Measuring OAL as a basis for load developement is akin to throwing darts blindfolded.
My load is 96gr H1000 powder. Hard to find a better powder for the 338 RUM. Everyone I know uses that. The powder charge is dependent on your particular barrel configuration and internal dimensions.... Start at 94 grains and work up.

as he has the photo of the .058". The .100" are so common, we don't even photograph them...... Not a big deal.
Here is the big deal that one needs to focus upon...................
With the factory Remington Sendero .338 RUM at the above performance level, it will beat the pants off of the 300 SMK out of a 338 Lapua Improved (I have one) and start nudging even the larger cases as well when they are using the SMK projectiles.
Preliminary tests with the Edge last summer gave us 3100 fps with H1000 and 3150 with Retumbo.... But, that was with test bullets. Now, the recipe is finalized and we will be testing the production bullets in the Edge just like we did in the .338 RUM.
With a 338 Lapua Improved we got 3245 fps with the 265s mentioned above....
Since the Edge and the 338 RUM are so potent and they are in a repeater variation, those are the two hunting rifles I will use when I travel to distant places to hunt. I will be pulling off the 338 Lapua Improved barrel from my single shot as it does not really offer much benefit over the other two. Then, I will put on an 8" twist .30 caliber barrel to tinker with the 210gr HATS at higher speed than my 300 Dakota XP-100 generates.
In short, if the 338 Edge or the .338 RUM cannot take care of it with these bullets in 265, 280 or 300 grains, a .408, .416 or 50 BMG would be in order.
This post is not meant to cover all the permutations or your possible loading questions, it is intended to reveal/expose the possibilities as to what can be accomplished if one gets motivated and goes to work and pays extremely close attention to bullet selection, powder charge, neck tension and neck cleanliness.
We measure powder to .02 grains and measure ID neck diameters to .00002" (twenty-millionths). If the neck tension is the same and the powder is the same and the tune length is correct, they go into a hole when the shooter does his/her job..... It is just a matter of having the correct tools of the trade.... Specifically, shooting stick and measuring tools.
