I want to make the most of my range time since it is far from home(3 hrs round trip). Is it viable to bring your reloading equipment to the range and adjust the charge, seating depth on spot? Could you share any tips or suggestions that you have found to be helpful if you have done so with success?
What caliber are you trying to optimize? At the range, are you loading outside, under a roof, or inside? Do you have power? Is it warm and sunny or cold and rainy? You said, "charge and seating depth" - so you settled on brass, neck ID, primer, bullet and powder.
Make up primed brass in advance.
You will need a seating die and a press, I would use a Wilson hand die and an arbor press. You need a table. If you can throw powder, you need a funnel but you don't need a scale. Adjust the throw for the best groups. Leave the best setting on the thrower. When you get home, throw a charge and weight it.
If you can't throw powder, you need a thrower or a scoop, trickler, scale, power, and you need to be out of the wind. If you are converting 12 volt battery power to AC, test your scale in advance to insure that it likes the AC that you are providing.
If you can't make enough brass in advance, you need to be able to size and prime the brass you just shot. Wipe the grup off the necks then neck size the brass - Wilson dies and the arbor press work for this. If you must bump shoulders then you need a press that can hold a bump die and a way to secure that press to a table.
FWIW, premade brass is better. If you have to full-length size and/or shoulder bump, it is still do-able but it becomes a trial. It takes half an hour to set up and tear down plus all the time to fiddle with the brass between rounds. Add that to your 3-hours of drive time and you don't do much shooting.
You may need to clean the rifle - you need a saddle, cleaning rod(s), patches, and solution. Pick up your used patches.
If you want to see all of this in action, go to a benchrest match. You can see 300 different ways to do this. The motor home guys have the sweetest setups. If you know a friendly welder, he can make a table that slips into a receiver hitch on the back of your pickup.
