The seating depth my have an effect on it, depends on how much you change. Neck tension has a lot to do with it as well.
The ES and SD really don't effect group size, in theory it does. In the following picture is a clean cold bore shot then the following group printed with my 6.5 Creedmoor...
Head spacing only applies to building a rifle. If it's already built and you've been shooting it, your alive and fine.
When you full length resize your brass you are resizing it to SAAMI specs, unless you have a custom die from Whidden for example. You can use the brass for any rifle chambered...
I trim all.new brass if the lengths are not equal, which happens a lot with some companies. This will help improve consistent neck tension and accuracy

Can you send me your fired cases' capacity, then velocity for any loads you have shot through your gun? Then I can try to tune QL to give you accurate data

Quickload is only good if I can true it to your gun, burn rate for your powder, and anything else your gun might do. I can run it but it won't be anywhere close to accurate

I think it's all personal preference. I run 22"-27" barreled hunting guns. I don't notice anything when I'm hunting. Shorter barrels are lighter by a little bit.

It's hard to beat a .45-70. If you are restricted to a handgun, .44 mag to the .500 if you can handle it. I personally use a Glock 20 SF since I know the gun well, I have 15 shots and I can shoot it and control it to deliver devastating results

Are you using VLD bullets? Do you have the proper seating stem installed for VLD bullets. Are you using Lee dies correct? There shouldn't be any movement.
That's why some dies have a small sleeve to keep the bullets seated straight. Also, try this trick.
When seating bullets, start to seat...
A proper ladder test allows you to ignore any horizontal stringing. Don't worry about wind or its point of impact compared to other loads.
You are only testing the vertical spread to find nodes. That's what a Ladder test does

Same loads as any other normal .308. All a shorter barrel does is improve accuracy at times. It's 50 fps loss per inch or gain depending.
Magnums don't need a longer barrel. I run a 22" .338 Norma Magnum AI with no issues, all I'm losing is velocity.
What bullet do you want to use? Load your...
For that large of a round, you should look more at using 7828, short cut or normal, H1000, the new IMR extreme,I think 7751 or so, look that up. It's a large caliber, you may want to try slower burning powder.
What primer are you using.? The ELD line of bullets like to be close to the lands...
The decapping pins/expander only straighten the necks, the die does all the resizing. I remove all of mine. Keeps the brass life, and I don't crimp any brass unless it's going into a semi auto.
Are the bullets shaved down from pulling them? Did you make sure to resize the pulled brass again...
Smoothie have you looked into doing a simple OCW test by DAN Newberry? It will save you a lot of trouble and guess work.
You only need a simple 100 yards to do the test. If you want more info PM and I can email over all the goodies for it.
The OCW will take into account clean, dirty...
Here's a factory AR15 with reloads with full length resizing die at 100 yards.
Here's using the neck sizing die on my 6.5 SAUM at a Mile, first shot was high so I adjusted.
Here's full length resizing on my Warbird at 200 yards
And for just fun a fly at 108 yards. With a stock R700...
Most bench shooters are using tighter chambers, hence the lack of having to full length size them, they don't grow much. But you are true, if we stuck with a factory gun, which most guys on here are using then there will always be a debate.
