Got my Hornady .224 55gr FMJ

    Now, I guess I should size and trim some 5.56mm brass.

    These will be my first .223 reloads. Do all these numbers seem inline?

    Trim to 1.750"
    Seat to 2.200" (or perhaps a bit longer...we'll have to see where the cannelure falls)
    25gr H335
    CCI #41 primer (I also have CCI 450)

    Sounds like the standard load for a 55gr FMJ.

    Everything looks good as long as you know Hodgdons lists 25.3gr of H335 and a 55gr. bullet as a maximum charge and you proceed accordingly. H335 is a great powder for the .223.
    I usually load them 2.225".

    Exactly what I've been doing the last three nights - prepping ~800 cases and tonight loading up the last of some Win bulk 55 fmjs.

    2.20 is a good COL but like stated, let the cannelure have the final say.

    2.200 is a little short to seat and crimp in the cannalure with brass trimmed to 1.750-1.760". I seat them to 1.220". 25 grains of H335 is a commonly used load and has been already mentioned that Hodgdon says maximum is 25.3 grains. I get about 3150-3170 fps in a couple 20" barreled AR's. Make sure all primers are seated flush or below.

    I trim mine a touch shorter than that, but otherwise your good.

    I have shot at least a couple thousand of the same bullet, I am very happy with the accuracy. H335 is also the powder I use and think it's a very good powder. I would start at around 24.5 grains and work it up.

    I'm at 2.255 COL, but I also run 65+ gr projectiles.

    My #3 shell plate appears to be out of spec, which is putting a severe damper on trying to get any .223 loading done. I read that some use the 9mm shell plate for .223, but that it's not recommended, because it can result in torn up brass. So, I tried it, and of course, the second case I resized that way, I tore off a section of case rim, leaving the brass stuck in the die. Before you ask, I did lube, using Dillon case lube.

    So, until I sort out the shell plate being unreasonably tight, I've given up on prepping any more .223 brass. I figure I could at least use one of my sized/trimmed cases to adjust the other dies. Following the directions for setting up the seating die, the first attempt at seating a bullet resulted in the projectile falling into the brass. I backed off the die a bunch more turns (in addition to the 2 after it touches the shell plate) and tried again. Seating the Hornady 55gr bullet to about the middle of of the cannelure, I get an OAL of 2.232". A loaded round of LC M193 is 2.252". I haven't pulled an LC bullet, but I guess the Hornady ones are either shorter or have a higher cannelure?

    Hornady 55 gr FMJ and Spire points are seated to 2.200" COL and that is what Hornady recommends

    Remember to full length resize first, then trim to 1.750"

    I think you will find the sweet spot for H335 to be around 24.5gr

    I would start with 10 rounds at 24 and work up in about .3 gr increments to Max load of 25.3gr, then test for best accuracy

    ETA I pretty much duped RustyFN

  11. I found 335 to be quite hot, even at a low-mid range load. Even the range officer had a look and noted flattened primers after one case got stuck.

    Start at a minimum listed charge. If you're just plinking, no need to make barn burners.
