Whats the general cost besides powder and bullets for a reloading set up, say 300 nm, maybe some 5.56, 308, 6.5 grendel, and 6 5 creedmoor, I know I need a press with some bits, a primer press? I'm not looking to dump a 1000 into it for now but what's like a happy middle ground?
Powders and Bullets alone can be troublesome to locate these days, and how. Primers are your other big supply issue.
Don't get put off by reactions to your caliber range......UNLESS you use them ALL all the time. I'm set up die-wise etc for 6-7 calibers, use one "frequently" by my definition, another halfway frequently, and the others rarely, they're for SHTF. I'm a low-volume long range precision shooter, so I don't need to churn out the reloads. Damned slow and methodical as it is....... The few times I let loose and spray a mag or two, it's with the cheap Russian ammo........what fun!!!
You definitely need a press with a couple of dies, for EACH caliber. For primers, get a de-capper and a "inserter". Franklin Arsenal has a good fairly universal de-capper, fits your hand kind of like a gun. They also have the "Perfect Seat Hand Primer" which is a dream, but others are available and somewhat cheaper. The right press kit will have a capper built into it. The more tools you have, in general, the easier proper re-loading will be. Get a "Dandy Trickler" for instance to help with your powder charges. And a "cheap" balance scales ($60-70) can give you really accurate loads, if a bit slow to properly use. Lee case lube is great for lubing your cases before sizing. Make sure to ear-swab some lube inside the necks, but don't overdo even if it won't contaminate the powder. And PERSONALLY, I recommend putting your powdered shells into a 50-round rack while reloading, then inspecting each with a flashlight FOR POWDER loads before pressing in bullets, to AVOID SQUIBS! The primer in an empty shell will push the bullet into the barrel, and if you don't notice and put a live round in behind it, LIFE WILL GET INTERESTING. OR NOT.
Good luck! If you enjoy cutting grass, you'll probably enjoy re-loading, it's kinda the same is some regards. Rote, attention to each blade of grass aka attention to detail, care and diligence, will give you a good or better than good round to fire.
ps. by the time you're competent, a Thou will probably seem like a happy middle ground, at the minimum.
