This seems backwards

I recommend that you reference more than one reloading manual just to be sure information is similar or corroborated from another source.

This^^^^^^^^^^. Early on in my reloading education I found out that it was quite confusing when it came to loading data from one bullet manufacturer or powder manufacturer. So if I was loading Hornady bullet I referred to a Hornady Manual, if I was using barnes bullets I would refer to a barnes manual and so on. The way I see it they have tested their product with certain powders and it works for them. The only time I do not refer to a manual is if the bullet I am using is not listed so only then do I rely on the data from a powder manufacturer that may have it for the bullet I am using.

Over the years I have lost the excitement of "experimenting" with different combinations so I have simplified things for me now. For example, I only use Hornady 75gr BTHP bullets for my AR with RL15 powder as this combination gives me sub-moa 5 shot groups at 200 yards, so I only buy and stock up on these two components for shooting, plinking and hunting. Same thing goes for the other calibers I shoot.

That is my goal as well. Find a single load that works for each gun and stick with it. Currently loading for 4 bolt guns, only one of which has a goal of sub moa if we can. The rest just need to be as accurate as factory, and go bang.

On a side note, was looking at some loads for 270 Win. Powder charges in range of 52 to 55 grains. Then compared that to new cartridges like 6.5 CR or 260 Rem. Same 130 grain bullet, but powder charges for that 38 to 44 grains. Aside from performance and all that, from a reloading perspective alone, you pick up an additional 40 to 50 rounds per pound of powder. If things continue to be tight, that is something to consider when making comparisons for new guns.
