Hi Hollow Point,
This is what I started out with:
Lyman and Lee reloading manuals: I read them both before buying anything. Then I watched a ton of YouTube videos for perspective, but there is good, not so good, and bad on YT, so read the reloading manuals for the solid foundation to help filter and interpret the YT videos.
Press: Lee Classic Cast
Priming: on press using Lee Safety Prime.
Case trimming: Lee Case Length Gauges, Lock Stud for drill, and Cutter with Ball Grip, and Lee Chamfer and deburr tool. Later I got the 3 Jaw Chuck which is faster than the lock stud adapter.
Balance scale: RCBS M500 scale
Trickler: RCBS Powder Trickler
Powder measure: Lee Dippers entire Powder Measure Kit. Heavy coffee mug for powder.
Head Space Gauge: Started with LE Wilson Case Gauges. Then switched to RCBS Precision Mic, and Whidden Case Gauge.
Ogive case length: Hornady Bullet Comparator kit.
Decapping: to avoid messing up my press and work area with depriming gunk and debris, I decided from the beginning to do all my decapping off press and therefore bought the Frankford Arsenal Hand De-Primer Tool. It was a good decision and its the only thing I use for decapping. But it is not designed for military crimped primers. That will have to be done on the press or other tool.
Dies: Started with the Lee Ultimate Rifle 4-die set for my calibers. I prefer to neck size only using the Lee Collet Die neck sizing die, and not full length resize unless the case needs a FL resize (and that is where the head space gauges are used first to check each case before that sizing decision is made). With my rifles (all bolt action) and brass I find I rarely have to FL resize, but I do so after 5 firings anyway.
Reloading trays: One blue Frankford Arsenal Universal, one red MTM Universal.
Bullet Puller: RCBS.
Tumbler: Lyman Turbo 1200, and corn cob media.
Calipers: I started with a cheapo electronic, and this was a mistake. It is not consistent and moves and flickers with variable thumb wheel pressure - junk. I then purchased a Hornady dial caliper and trust it much more, as it does not move when the thumb wheel is closed.
Later with experience I branched out with additional specialized gear and dies and measuring tools as I learned more about seating depth, neck turning, neck tension, concentricity, sonic cleaning, annealing, etc, it never ends. But the above basic kit got me started for a reasonable cost.
Reloading is super rewarding.
