i would get a delrin ramrod, several inches longer than your bore. range rods are great but when im out in the woods i carry a delrin rod which is lighter, pretty much unbreakable, and because mine is meant for a smaller caliber than what im shooting (im shooting .45, i have no idea what caliber my rid is for but its smaller) it is almost impossible to get it stuck in the bore. it has several tools cleverly hidden in the rod for fishing out ball and patch, threading on your various tools and so on. you can buy them at october country in the states
an adjustable measure is a must for working up loads, after that if you want to move to a fixed measure or a spout thats up to you. obviously you need patch ball and powder, what kind and thickness/diameter you have to figure out, i like the oxyoke pre lubed patches but i have also found using 7 parts ballistol 1 part water as a mixture to lube my own patches works well but there are plenty of other methods, id keep it simple and experiment as you go
id buy a ted cash cap holder, either the oval one or the snail capper, trying to fiddle with caps with your bare hands is a pain
if you are going to be out in the woods a lot get a possibles bag, i got mine here

last id recommend a brass powder flask with the cross bolt style dispenser not the thumb lever with the wrap around spring, they both work but i think the cross bolt is a more robust design.
don't waste money on fancy solvents, hot water with some soap does the truck every time
