Reddit mentions of Little Crow Gunworks LLC Worlds Finest Trimmer 2 Housing/Cutter Assembly

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.
