Excellent, good to know. I have just loaded my first batches but have not shot them yet.
Data is pretty scant, but I have gone for 69-71gr.
I am in the right ballpark?

Most probably it's not a node but chance. Yes you can come to conclusion "it might be a node" but you can never say "it's a node" (some won't believe in nodes, I've seen enough that I can at least partly believe).
Regarding the initial pressure testing, I like to load 2 cartridges per each step and record the muzzle velocity. That way you get a rough idea of how the data fits your rifle, in addition to pressure signs.Save the brass in shooting order, so that you can measure and/or make additional observations while preparing them for next round.
Apologies I missed this! How have you got on? I can look out my data tomorrow if that will help?

Not to worry and thanks for the offer. I am pretty much there now though.
73gr gets me 2,500fps, with a crimp. The crimp seems to increase pressure and hence velocity slightly.
I did get upto 2,600fps but pressure was too high. Much over 2,500fps seems to give me the occasional stiff bolt lift, which I don’t really want on a dangerous game rifle.
I've watched shooters of such chamberings when at a BSRC range bench, be it for zeroing, load testing or - more often than not - figuring out how to get the scope to stay put.
They don't last long before returning to the vehicle for their 243 or some such!

Your maths may well be true for the scenario you describe.
However what you have not figured into the scenario, is that once you start reloaded, you WILL shoot more ammunition.
Load testing, load development etc.
Reloading is a passion in its own right.
I've never believed in the cost saving bit.

Reloading is an activity that scales quite well if you have multiple chamberings.
You might not save very much, or anything at all reloading 308 Win, but when I take a little think about what I am reloading for at the moment it is:
308 win
30-30 win
303 British
32 win spl
35 Rem
375 h&h
Neither of the first two, or arguably even three, would justify reloading on their own ordinarily, but the last three are pretty expensive. Add to this, my 30-30 and 32 are single shot rifles which means I can (and do) load them with pointed bullets which are not really available as factory loads. And that really is a big part of the point, by assembling your own ammunition you can have combinations that are not commercially available.
Especially good for the 375 if you can get it conditioned for deer in England as you can load it up with "light" 235, 220 or even 200 grain jacketed or between about 285-315 grain cast, bullets and it becomes a very sweet shooting (if admittedly heavy) rifle on which you can gain a lot of stalking experience prior to using it in anger against DG.
It's all personal of course. Any reasonably intelligent person can usually find a way to justify this sort of thing to themselves

For sure it's a fun world.
No doubt there are parallels to the problems that climbing guides on Everest have.
Clients with loads of money, but no idea.
On the flip side, if money was not a limiting factor would i try lots of different things?
Probably.

Yes I found a crimp to be essential in the .375 as the recoil would set back the bullets in the cases. I’m not generally keen on Lee dies but the factory crimp die solved the problem.
2500fps is plenty as you aren’t likely to be shooting more than 100m

My experience with the 375h&h so far is the components for reloading is very hard to find....but, I've found components easier than I've found loaded ammunition.
I reload for my other rifles so I already had a set up but if I didn't it would certainly make sense to start reloading especially with bigger or less common calibers. A reloading set up doesn't have to cost a fortune, there is always good second hand bits and pieces for sale.

If you don't have a Lee crimping die you can always adopt the highly technical H&H approach that is a hammer & punch:

That makes the primer look very small indeed!
