Also as I am finding out it takes A LOT of equipment. Especially when you start talking about changing seating depth and measuring run out. All this stuff really adds up in a hurry as far as cost goes.
I tend to disagree with the oft mentioned "it takes a lot of (expensive) equipment, especially when you (list all those exact things you must have perfect to make the perfect ammo)" Here's why.
I started reloading .308 Win. in the mid 1960's with a used RCBS Jr. press and a standard RCBS full length sizing die and seater. A National Champion suggested I have the sizing die's neck lapped out to 3 thousandths smaller than a loaded round's neck so the expander ball could be removed and would no longer bend the sized case necks out of near perfectly straight. I decapped fired cases with the bullet seating die with the decapping rod in it, then cleaned the cases in a Thumblers Tumbler full of rice before lubing and sizing them.
Since then, I've got 5 other RCBS standard full length sizing dies and lapped out their necks to different diameters in .001" steps between dies for different case neck wall thicknesses and bullet diameters. There's about 2 thousandths spread across their body diameters but that never seemed to matter 'cause there was that much spread across the SAAMI sped'd chamber body diameters. Didn't matter how much clearance there was between sized case body and chamber body; they all centered perfectly up front anyway when fired.
Made a cartridge spinner using two 7-inch pieces of 1/4-20 threaded rod with a plate at the back end, a nylon washer on each rod 1/4th inch in front of the plate, another nylon washer forward of the back positioned to touch the bullet just in front of the case mouth. Nuts locked the washers for spacing; it worked well for 30 caliber magnum cases with more space between the washers. Then put a cheap dial indicator bought at a garage sale for 15 bucks on it with its plunger angled to the bullet opposite where it touched the front washers. Laying a round in this "expensive" tool, pulling it back against the back plate with the dial indicator back 1/10 inch from the tip. Readings were as good as a couple of high priced ones other folks let me borrow.
The bullet seater's stem was a bit too big for the hole in the die, so I wrapped some thin tape around it to make it a snug fit. Didn't seem to help bullet runout as whateve runout there was matched the neck's angle to the case axis. Tried a Wilson chamber type seater and it didn't do any better. Bullet seating depth for rounds to be single loaded was made by seating a bullet in an empty sized case by chambering it, then setting the seater die's stem to touch it then back it off half a turn. Bullets seated for loading from magazines were done so about 1/16ths short of maximum magazine length. Either way produced excellent accuracy that several thousandths changes either way didn't help.
Last time I used that old sloppy press and that die to reload some ammo, I won the Colorado State Long Range Championship with it. A year later, some 20 + left over empty sized WCC60 Western Match cases were stuffed with the same lot of primers, powder and bullets then used to test a new Palma rifle's barrel; put 20 of 'em inside 3.3 inches at 800 yards.
The ram on that old press had gone through more ups and downs than the mattress springs on a famous bed about 69 years ago in Hawaii. And those dies had more properly lubricated, long, hard, round things pushed into and pulled out of them than Mamie Stover did working on that same bed during WWII in Honolulu. That die was cleaned just as often, too.
I replaced that old Jr. press with a Rockchucker as it was easier to use full length sizing belted cases. The Jr. was then used most of the time just to seat bullets or deprime cases. But they both produced equally accurate ammo; the Rockchucker's as tight as a Nun's after much use, the Jr.'s as loose as Mamie's.
