There will never be another one of these for me.

Which cartridge do you figure they're placing the cannelure on that particular bullet for?... If it's not for a 223/5.56...?

I don't know, ask Hornady.

It's a generic .224" bullet. It can be fired in any number of .22 caliber cartridges. 22-250, .222 Rem, 222 Rem Mag, 22PRC, 220 Swift, 223 WSM, etc etc.

Why are you assuming it's designed for a particular cartridge ?

Lyman #48 shows a 2.260 OAL with 55 grain soft point.

That length is 2.260. The cannelure means nothing to me in rifle loads. It chambers freely, and the bullet is seated to the base of the neck.

That's mag length for AR 15.

I already know why the Bullet Engineers at Hornady put the cannelure where they did on that bullet... I was asking you, if you had any thoughts on why it might be in that particular spot? Lyman 48 mentions the Sierra SPT #1360 as their 55gr bullet tested in a Colt AR-15 at maximum magazine length. I assure you the cannelure on your Hornady bullet is not for the ".222 Rem, 222 Rem Mag, 22 PRC, 22BR, 220 Swift, or 223 WSM etc, etc" They put that cannelure where they did because it fits the most common .224 centerfire cartridge someone might utilize it in - that being the 223 Rem.

And yet, seating to that cannelure ensures the cartridge will not be at the OAL listed in the Lyman manual.

I shall, however, bow to your encyclopedic knowledge of all things Hornady .224. I confess, this is the first time I loaded for the .223 Rem. I am mortified to find that my cleanly chambering and shooting handloaded cartridges are not seated to the cannelure of a bullet specifically designed by Hornady for the 223.

I wonder what the shooters of the other 22 caliber centerfire cartridges do ? Do they need to petition Hornady to move the cannelure for their individual rifle, under penalty of internet censure?

I shall also review my 30+ years of reloading experience. I'm clearly doing something wrong.

I meant no disrespect, good man. I also respect your 30+ years of reloading experience, and desire to follow the book.... you're using a very different bullet than that of the one utilized in the Lyman 48. Seat it wherever you'd like... My apologies, hope you're able to get it shooting better.

Rifle bullets seated out close to the lands group and shoot better. It's common knowledge in benchrest calibers. The same applies in 223 when one doesn't need to fit them in an AR-15 magazine.

In these gun forums there will always be those who try hard to find something wrong with what you're doing.

You were provided with that information straight from the Hornady #9 Reloading Manual in post # 12.

Doesn't really matter though I guess as I once had a ~223~ bolt action that I could seat a 75 gr Hornady Match bullet out as far as possible before it began to lose 100% contact with the case neck.

Goofy looking as heck with all that bullet hanging out. Heaven only knows what the OAL was but it didn't matter as I use a sled and load singles. I can still guaranty you that those loads never once hit the lands.

How could that be? Pretty simple, actually

The throat had eroded so far in that that simply weren't any lands left to hit.

I still have and shoot that same ~223~ today. I bought it brand new 3-4 years ago.

Of course, I should probably mention that the ~223~ I'm referencing above was still wearing the OEM barrel at that time, and who knows how many thousand rounds I ran through it before then. So, I bought an aftermarket barrel. It was great!!!! But, after thousands of rounds, I wore it's throat out too.

I'm now on my 2nd aftermarket barrel. Hoping it will last at least until summer when I retreat back inside.

As always, YMMV.

I wonder what the shooters of the other 22 caliber centerfire cartridges do

I hope they start by looking up the data for their specific Caliber.

The same bullet I mentioned in post #12 is also listed in in the 22-250 section of Hornady # 9. OAL is 2.35 instead of 2.20. (+0.150) Case trim length is listed as 1.902 for the 22-250 vs. 1.750 for the 223. (+0.152) Couldn't tell ya why it's 0.002 different, but the relationship between the end of the case mouth and the Cannelure would likewise only be 0.002 different.

But, wait! That ain't all folks!

I (now) use a Comparator to set my OAL as the chamber/lands between all (3) 223 barrels I've used were not all identical.

My current barrel has a "VLD" chamber, with the throat designed for a specific bullet shape. The exact same 75 gr Hornady bullet I mentioned above is hard into the lands if I were to use the same SAMMI OAL I used in the previous barrels..

Conversely, I can load a 60 Gr Sierra TMK at their recommended OAL (Max magazine) with room to spare as it's a different profile than the Hornady 75.

Just when you thought it was getting easy,,, LOL!

Truth is, it can be easy. It can also be as difficult as one chooses to make it.

I don't get the hangup on cannelure for rifle loads either, I'm not crimping into it anyway.

I once bought some bulk 224 55gr FMJs, might have been remington or winchester. The cannelures were rolled into the bullets at all sorts of varying metrics, it would've taken me a whole week to seat all those to the cannelure.
