Wilson neck size dies with interchangeable bushings, good powder throw, Arbor press, and you're good to go.
Hunter Bench Rest shooters do it regularly.
This is where you get to realize how little 1/10 grain of powder means to an accurate load.
I guess you could set up your tooling in a kit to be set up at the range, but it's just another waste of good range time.
Your standard powder throws are OK, but they just aren't repeatably consistent, and you can't make minor adjustments to the charge with any precision.
You will need tools made and adapted for field conditions. The Lee hand press is a cheaper way to get into hand loading at the range. It's only meant to neck resize or size pistol cases, but it does assemble very accurate ammo.
I used Lee hand press beside my Wilson arbor press to check consistency and things like runout. I was pleasantly surprised by how good the comparisons were.
I still have the Lyman No 45, "Ideal" powder measure I used for measuring HBR loads up to 25 years ago.
The Lyman #45 is an expensive, small reservoir, micrometer-adjustable powder throw, that is smooth as glass to operate. I mounted it to my "spotting scope" accessory box, which also held the arbor press, powder, dies, neck bushings, etc.
Even the micrometer equipped RCBS and similar powder throws have larger powder reservoirs, which quickly lose consistency when it comes to the weight of charges thrown, no matter how meticulous and consistent you think you are with your "system" to throw consistent charges. Wind even has adverse effects on electronic powder dispensers.
WIND is your biggest enemy when it comes to weighing powder charges.
You have to set up whichever powder throw you use at home and learn how to adjust the micrometer type utilized to be able to make incremental changes to your charge weights.
It may not be feasible for cartridges such as the 223 Rem, or similar small cases, but anything from the 22PPC up, it should work fine if you learn how to use it, with the components you have along.
I really liked the Lyman No 45 Ideal, because I could make changes on the dispenser, record them in my manual, then go back to the original setting, and make other changes from that known point.
Not as easy as pressing a few buttons and letting the unit do it for you, but after you're convinced of your competence, very repeatable charges could be thrown.
I had a table made up for the adjustments on my powder throw. It took a little trial and error at home on the loading bench to work out the correct "knocks" at the top and bottom of the throws, and it did what I needed done.
I saw some very elaborate setups for reloading at the range, for shotguns, handguns, and rifles. None of them bucked wind well, other than the one a fellow had set up in the back of his van, which was dedicated for the purpose. He may have used it at home as well.
