Reddit mentions of Lyman Products E-ZEE Trim Hand Case Trimmer Rifle Set

I would recommend upgrading to a nice digital scale, it will make things easier.

Maybe get a few of these if you haven't yet thought about how you're going to store your loaded ammo.

I have that same tumbler, works great. I would also suggest a separator for afterwords. Some brass polish is nice too.

I think that kit comes with a hand trimmer, but I would recommend a larger one, your hands will thank you.

I went with a Lyman kit for my starter set, and while it's a lot more expensive than yours, I've been very pleased with it.

When you start doing 223 you'll also want a case length trimmer. This one works pretty well for me.

I'm currently making 300blk out of 223 cases and just loading standard plinking rounds. I'm going for lost cost per round (CPR) that I can do.

Whatever press you very will typically work with any dies. I use a Lee single stage press and Lee dies, personally. I like doing steps in bulk.

Steps:

1. Look at all my 223 brass and pick out as many lake city brass as I want to covert.
   
2. Use a harbor freight 2in mini cut saw and some type of jig (I made one myself, but there are better ones on Amazon) to cut it to the right length.
   
3. Decap and resize using the decap/resizing die.
   
4. Depending on the trimmer you will either trim the case to length before priming, or you can prime first. I use a Lyman Ezee Trim and bought the extra 300blk pilot for it since I also do 223 and plan on 308. BUT I'd personally say to get the world's finest trimmer 2 of you plan to do bulk as well as other calibers. I was enough money on trim serious that failed that I could have just bought the world's finest and been good. If you don't plan on bulk and want to save some $$ the Lyman is fine. If you use the Lyman you need to prime after trimming. World's finest you can prime whenever. With the Lyman you may need to resize again if you use a hand drill to help with the trimming. Sometimes mine opens the case mouth a bit and causes b to not seat correctly.
   
5. Trim or prime after doing whatever you didn't do in the last step.
   
6. Find what powder and load you want. I use a Lee perfect powder measure. Others may be better. Mine gunks up after 100 rings and I wind up needing to clean the internals of I leave pretty in it overnight because they make the lever get hard to move. It also spills a little powder out the side in mine. This may not be the case with others.
   
7. Inspect that there is power in every case. Just put them all in a holder and use a flashlight to check.
   
8. Seat bullet to desired length with seating die.
   
9. Crimp bullet if using in a magazine feed rifle. This is personal choice for people. I like to do it this way. Others may not. If you are going for plinking amp it usually won't matter either way. Precision ammo you will have to test with and without to see if one gives better accuracy.
   
10. Shoot and test it. Put 3-5 round s in a mag (if shooting semi-auto) and shoot all 3-5. See if it cycles reliably and kicks the bolt back after the last round. You can technically do this with 2 rounds in a mag, but I like to test to make sure they feed in the mag right as well.

This is what I use for trimming. Works fine with a drill. Fast and cheap

I would invest in some case gauges and headspace gauges. This way you can do a plunk test to make sure they're in spec without actually doing a plunk test in the firearm. I tend to check every 5-10th round to make sure they all seem to be in spec.. There's nothing worse than loading 200 rounds and find out that you maybe accidentally changed something or something moved and they're all out of spec.

I use the Wilson Case Gauge and it works really well. Lyman has one for about $21 you can try. I was going to get that one and changed my mind after I heard a story or two about the Lyman one not being stainless steel and got rusty.. but I live in the desert and don't have a swamp cooler so I shouldn't have to worry about that. Didn't think about it at the time.

Right now for a cheap way to trim, I use the Lyman E-ZEE Trimmer attached to my power drill.

You'll also want a good pair of calipers. I use the Hornady Digital Caliper and it works well enough.

If I think of anything else, I'll update.

This thing is EASY and affordable. I use it with my cordless drill and/or my smaller drill press!

I don't know what kind of volume you plan on doing, but you might consider the Lyman E-Zee Trim as well. It will allow you to trim by hand or use a power drill. I recently bought one and can trim, de-burr, and chamfer a .223 case in a bit less than 15 seconds.
