The headspace comparator kit will show you how consistent your base to shoulder measurement is. If you're using a regular FL die then neck tension is what it is - you need a bushing die (and high quality / neck turned brass) - or a collet die - to start playing with neck tension. Annealing helps too if that's an option for you.

Great info, thanks!

I'm always using the same brass (same firings too). Could do a better job of cleaning lube out. Always trim to same length. I'm not sure how to set up the die for shoulder bump, but will get on the google for that.

I am using a regular full length sizing die for both my 7mm rem mag and 7mm08. Kind of hesitant to fork out for another die without trying the other stuff first.

I'm keen to get things as precise as possible, but the reality is it will be used for hunting once I'm set up - not chucking pills at steal at crazy distances. If I can reduce the ES without having to buy too much gear that will be awesome.
