My first reloads...

5 rounds of .223. Hornady 50g GMX bullets. IMR 4198 (19.8g).

Bullets look strange to me with that 'recess' in them, but ran out to the range to fire my first ever reloads.

Love it. They worked great.

Nothing big for a long time reloader, but being my first, it's quite an adrenaline pump.

How did you determine seating depth? That "recess" is the cannelure, the design seating point, for those who crimp. Nothing wrong with not using it, I just wonder how you did choose the seating depth.

If its a bolt gun or youre looking for getting close to the lands itll be fine stepping over the cannelure. I see no reason to do so otherwise. But if they worked fine and you are happy then youre good to go. Congrats on the first loads

I tweaked my bullet seating die until the overall length was per spec for .223. Clearly I wont be buying any more of these bullets but I have a load of vmax's coming, so I'll get to play with what I have until those show up.

If they work well in your gun fine and are up to spec then the cannelure is moot. Smoke em if ya got em.

What EXACT spec are you talking about? Are you talking about 2.260" or some other, smaller number?

2.260 length.

Arbo, I see this a lot. Here's a serious question. What suggested to you to load to that length?

I am guessing you don't have much of that bullet in the neck of the case.

agreed. I think not sure dont own a .223 but i believe 2.260 was the max length for function in an AR mag. Not the lenght they all have to be. Your manual said 2.260 for these bullets?

My manual says a MIN OAL of 2.21

What seating depth are you thinking it should be david_r

Seating depth is about .25" into the case.

I just did that to get the OAL. And thought that pushing it in further would shrink the inside space and up the pressure.

I think I'm seeing a pattern here. Thank you for helping me understand. Pistols it is pretty darn important to never go below minimum COL. People are also admonished to load long as long as the magazine functions. Rifles, reduced COL is less of a factor.

I am going to hazard a guess that Beentown's data is "As tested," not minimum COL. Even if it's from Lee that says "Minimum COL," it is as tested.

That's where I would start or at 2.200" where IMR shows with that powder. Then I would probably seat to crimp groove and see how the rifle likes that.

If you don't have Hornady data, use IMR's with a similar bullet weight. Your bullet should be seated with the base to about the bottom of the neck. Or just run it in until you can crimp in the groove if you are going to crimp.

Try this. Take one case, fill it up with a full charge and look at how much more full it is compared to the minimum charge. At minimum charge, you could seat the bullet to take all that extra space that was taken up by more powder. Make sense? If I have two grains of air in my cartridge or I put two grains of powder in that air space, which is going to produce more pressure?


I should have started out with a congratulations. It is a very good feeling to load and fire your first rounds. I wasn't intending to take the mickey out of you. Let's get those bullets pretty, too!

I will go out to the shed and seat one to crimp... I don't know the answer to the question of pressure you asked.

Correct. I tried to find some data for this same bullet only in SST form. Neither of my manuals have anything on the particular one. I was going to start with a 2.2 and go from there. Using CFE 223.

Ok, if I cover the cannelure the OAL is 2.176. I can get to 2.20 with a crimp on it but the majority of the cannelure 'showing'.

Out of curiosity I measured some winchester I have out there and it is OAL 2.21, and some lake city that is 2.25.

I made 10 @ 2.20 with the crimp, will get out with them Saturday.

.05 isnt much of a difference IMO

Shot the 10 today @ about 75 yards. Seems they work well, now to just get more consistent shooting with the red dot. ;)

Made up more rounds with the bullets I had left. Will write it all down in a notebook for future reference, and eagerly away my 60 grainers from cabelas.
