Hornady .223 55gr. sp Bullets

[DPA]

I am testing loads for a friend using Hornadys SP 55gr. bullets.
These bullets have a cannelure. I like to seat my bullets so OAL is 2.26 or 2.25, but with these bullets I have to seat to 2.20 in order to get the cannelure engaged. At 2.10 OAL the cannelure is about halfway into the case. The case length has been trimmed to 1.70. Why are they designed to be so far away from the lands? These loads will be used in AR platform. I wonder if they are designed for bolt action and not ar.

Feeds better. Less chance of nose damage. Not an accuracy bullet for me

You don't have to seat the bullets to the cannelure, unless you are crimping. That is not required, even in an AR platform.

I used the hornady FMJ BT and I dont seat to the cannelure almost ever, i always use an OAL of 2.26-2.25 like yourself. But the cases are trimmed a bit short no? I'd try to seat those a little deeper to make sure you've got sufficient neck tension, i trim mine to 1.75 and still done use the cannelure, as I don't crimp

DPA, your cases are a bit short. They should be in the 1.740-1.760 range.

Either way, if they headspace and fire fine, I wouldn't worry about a COL of 2.200".

Sorry for the typo. guys, I was using my phone to post question. (I was in the garage) Case length is 1.75.
It appears I might have asked my question incorrectly. More precisely... why would a bullet be made so you have to seat it so deep in order to use the cannelure? Whenever I've used a bullet with a cannelure (rarely) it always seemed to line up.
243winxb: I concur, they are not very accurate.

For feeding, but, as posted, you can seat them to a longer OAL if you wish.

Seat to your COAL, do not seat to the depth of the cannelure. Cannelure is only for crimping, there are people that crimp AR rounds and there are people that don't crimp AR rounds, I am on that does not crimp them and they cycle just fine.

Only time i crimp the rounds is if the neck tension is gone and wont hold the bullet, then ill crimp it, and hope that, that particular case gets lost.
