Recommended Products for the Beginning Reloader from Midway Web site
(Rifle & Pistol)
Reloading Manual: Accurate Arms, A-Square, Barnes, Hodgdon, Hornady, Lapua, Lee, Lyman, Nosler, Sierra, SPG, Speer and Vihtavouri.
Have at least fullsize ones and get all the freebie ones you can snag. Or down load from the web sites of the powder mfg.
Press: Single Stage, Turret or Progressive
I think a single stage press is the way to learn on. Then go to a Dillon! You will always need a single stage press! This way you learn the steps of reloading prior to accomplishing them in one stroke with a Dillon
Dies
You want to buy good stuff. If you do go the route of a Dillon you will be wasting money by getting other mfg die sets for the pistol rounds. What I mean is that you will end up with useless dies and having to buy a Lee FCD or the appropriate roll or crimp dies if you don't get Dillon dies for a Dillon press! Redding makes a Professional Series of dies meant for progressive presses. Otherwise any die set will do! Just remember you can not seat the bullet and crimp at the same time! Not going to happen in a million years, they are two seperate and distinct operations! A regular Pistol die set comes with a Sizer die, Expander die (not needed with a Dillon), and seater / crimp die. Auto cases get taper crimps and revolver cases get roll crimps. The Lee Factory crimp dies is what some use to crimp with, and get good results! Rifle Dies are the Sizer and seater die! Again here the seater is a crimp die too!
Shell holders (if the die set doesn't have them)
They are universal for the most part, just different stock # with each mfg. Some can be used with more then one caliber ie 45ACP works with 308 3006 270 260 243
Tumbler: Media, Polish, Sifter, Bucket and Clear Lid
Not necessary at first but a good idea to clean your brass before sticking them into your dies!
Loading Block (caliber specific)
MTM makes a nice one that covers many cartridges
Case Lube (you won't need if using carbide dies)
Case Neck Brush
Can use a worn out bore brush, too
Dial Calipers: Stainless Steel or Electronic
Either as they are a must for reloading!
Case Trimmer
Lee makes individual ones for each cartridge that work okay, Possom Hollow makes a nice unit, too! Of the lathe trimmers the Wilson is the best, of the powered trimmers Giruad is the Rolls Royce!
Deburring Tool
Some are combo tools debur and chamfer
Primer Pocket Cleaner
Some are brushes or scrapers, and other use the primer pocket uniforming tool to clean out the primer pockets. A must for rifle cartridges. I have never done this to 45ACP's
Primer Tray
Only necessary if loading pick up tubes ie Dillon or some press mounted tools!
Priming Tool (if the press doesn't come with a primer attachment)
I like the RCBS tool that does not use APS strips. Sinclair makes the best, and do not bother with Lee one it breaks! And, you pay to fix it! RCBS is the deal!
Powder Scale
Balance Beam or Electronic it is your budget that guides you! RCBS has there manual stuff made by Ohaus and Pact makes the electronic ones.
Powder Funnel
Careful which one you get some are universal and others are caliber specific.
Powder Trickler
A good deal for trickling up loads on the scale!
Powder Measure (nice for faster powder charges)
Lee has good rep with stick powders is low cost. The best is a Harrell! Redding makes a darn nice one with a micrometer stem!
Bullet Puller
This is a must! The kninetic is cheaper, whereas it is messy. If pulling a lot of rounds the collet type is the way to do it!
Ammo boxes and labels
Case lube
This is more for any bottle necked cartridge, in pistol cartridges you can get carbide sizer dies. But, there is a reason on a progressive to use a spray lube on pistol cartridges it makes things way smoother! Some like the Dillon spray lube others like Hornady One Shot.
Most of all you need to get notebook to record your results! No need to go over the same trail twice!
A chronograph is great for working up loads. But, the #'s game can be a bit distracting!
Be safe! And enjoy your new hobby!
