I usually go to 2.23 OAL and have no issues. As per the Hornady manual, 2.24 is the max OAL for .223.
The official max length is, as you stated, 2.260. But given manufacturing variances in mags and oal variance in your loaded rounds, I find 2.250 to be the max I can use and still load into and feed from the mag reliably.Do you guys load to the specs in manuals? Im finding them long for my LAR 15 pistol mags. Im loading them to this length 2.260 but find them hard to load easy and have had some broken ballistic tips.
Cheers!!
What do you have the gas setting on?
If your rifle is broken in, try your gas setting at 2.
