Get a Range Rod that is 48 inches long. I have one made by Treso. Its stainless steel. You can also get range rods in Brass- both solid rod, or brass tubing from October Country and Cains, among others. They will make it to whatever length you desire.
I would not buy the jags Until I got the gun in hand. You want a cleaning jag to be .030" Smaller in diameter than the bore diameter of the barrel. That way, you can use soft, flannel cotton cleaning patch fabric to clean the barrel, and the fabric will slide nicely OVER the lands, instead of shoving crud ahead of it down into the breech end of the barrel.
When you pull back on the rod, the grooves in the jag will Catch on the cotton patch, which will blouse outwards from the jag. The catching of the fabric will push it into the grooves, and wipe the lands , pulling the crud out of the barrel with the now dirty patch.
Too many "packaged" jags come in too large a diameter for most guns. Its not a problem unless you don't own a hand drill, and a file. If you do, you can file down the brass jags to the correct diameter.(You need a caliper for this, too.)
Avoid jags that have threaded Brass stems at the back end. Brass work hardens, and some day, without any particular stress being placed on the jag, the threaded stem will simply break off, leaving the jag and patch stuck in your barrel. Track sells( as do other good vendors) jags that have a steel stem that is threaded in either 10/28 or 8/32 tpi. You want the thickest diameter stem you can buy for this kind of work.
Buy an adjustable powder measure that is NOT attached to the horn.( Safety) Get one with a funnel attached to the trunk of the measure to make it easier to pour the powder into the barrel.
Later, when you know the powder charge you will use for hunting, you can make a "fixed" powder measure out of wood, or antler, to use to measure out your powder charge in the field. Fixed powder measures can be as crude, or as artistic as you desire. The function is the same.
As general Advice, don't run out and buy a lot of 'Stuff' before you have the gun in your hands. Retailers love guys who do buy without knowing what they have. Find some local BP shooters- a club-- and take guidance from other shooters on the best sources of the things you need, and the things you don't need. :hmm:
You will find that attending " Blanket shoots", where your entry fee requires you "donate" something to be a prize that is placed on a blanket, and the winner gets first choice, and on down to the last place finisher. Its a great way to get rid of stuff you bought that you can't use! :haha: :surrender: :thumbsup:
I bought both a patch puller jag, and a ball puller jag when I got my first rifle. I have yet to use that patch pulling jag in any of my guns. :shocked2: I know. :shake: If I didn't have it, I would need it every week I shoot :blah: :youcrazy: :nono: , so I keep it. It chases those "goblins" away, maybe! :idunno:
I don't even encourage new shooters to buy a hunting bag until they have a chance to shoot the gun, and get used to loading it. Most first time bags are Much too large, and guys carry too much stuff into the field. As you gain experience, you find yourself leaving more of that "Stuff" back in your range box at home, or in your vehicle, and carrying less and less gear. I am at the point of not really needing a shoulder bag at all when I hunt, making due with the pockets on my jackets, or with a belt bag.
A Ball block that holds no more than 6 PRBs ( 3 for deer hunting)already lubed is more than sufficient for most hunts.
Pre-measured powder charges in separate tubes can be carried in a pocket.
A modern rifle cartridge casing can be turned into a priming powder "horn", with a cork that fits the mouth of the casing- again, carried in a shirt pocket.
A few cleaning patches in either a container, or carried dry, in a pocket, will take care of that need.
On most hunts, unless its small game, varmints or waterfowl, you will take so few shots, I don't even bother with ball and patch pulling jags. They can be carried in a small tin in a pocket, or day pack( with flashlight, Rope, sandwiches, water bottle, compass, extra knife, towels, etc.).
I now use my belt bag to hold my wallet, keys, knife, and coins if I happen to be in my elk hide, leather pants with no pockets. If I am hunting only a few hundred yards from my car, I don't even take a day pack, opting to carrying a canteen on a web belt instead.
I may not be Pretty, or Historically correct, but this is not a fashion contest either. :shocked2:
