I have been loading for about 50 years. Currently we have dies to do over 80 different cartridges. I highly recommend a strong, cast iron, O-frame press as it maintains tolerances very well. RCBS Rockchucker, Lyman Orange Crusher, etc are all very good. Some 20 years ago I started keeping load data in an Access database which not only preserves the information, it can be retrieved and grouped as needed in a couple of key strokes. The obvious thing is to record what works but I also track what doesn't work. The database shows trends and now we can predict where to start for an accurate load. For example: we had used Unique for a wide variety of mid range handgun loads but Power Pistol which has a similar burn rate showed consistently better accuracy and as a plus it burns cleaner. Only good records can provide this feedback. There is a lot of good equipment out there and don't be afraid of used stuff. Store your ammo out of direct sunlight and in a dry area. It is nothing to grab a box loaded 30 years ago and it still shoots like it was loaded yesterday when stored correctly. Hope this helps.
