I’m one step closer to loading for the AR. Midway had 223 Factory Crimp Dies in stock. I also ordered the Lee Hand Press kit, and four extra breech lock bushings. If I can do sizing on the couch watching TV, that would be awesome. We’ll see how it ends up working out.
If you are loading boat tail jacketed in an AR15 you should be good with 3 die. Full length sizing, seating die and factory crimp.
For your rifle sizing die, you will need sizing lube or paste.Billy posted a good recipe on here some where that works well, if you do not want to just buy a tube of paste. Lanolin and alcohol. You do not want to get one stuck. Not a good time.
After you size, You will need a case trimmer. If you do not have one.
I use one of the Lee " finger twirlers" sitting in my chair watching tv, or chucked up in a drill if I have a lot.The main part costs about 8 bucks and the pilot about the same.
If you get into flat base bullets or lead you will want to buy Lee universal neck flaring die. Flat base shine under 150 yards and usually cost less. Boat tail is for long distance and believe it or not. They tend to not be as accurate at the shorter distances.
You can get buy loading flat base without it, I used a pair of needle nose for months just insert in the cartridge neck and twirl a bit, just enough till the bullet will go in without scraping. Do not get too carried away as you will fatigue your brass before it's time.
Now if you ever start going long distance or get a bolt action, you will eventually want- need a neck sizing die to use once you fire form the brass.
ps . As soon as you receive your full length sizing die. Call Lee and order an extra decapper pin for it. Tell them it broke. They will only charge you shipping. You will break your first one, probably sooner then later. You will thank me when you do.
