I found 2 different lots of 180eldm Hornady ammo to be very different so I pulled down a round from each. One had what appeared to be RL25 or 26 in it and the other had a ball powder in it that looked like staball hd.

The RL powder ones clocked about 2770 fos and the staball ones clocked 2850. This from my seeking havak element with a 22" barrel.

I don't have many rounds down it yet but I've loaded it to where I got about 2910 with a 180 but that load was fairly warm. The load I've settled in for now is a 180 at 2850 fps. I'm probably losing at least 60 fps from what a 24" barrel would get maybe even more but I like the way the 22" handles. If I were building a rifle I'd still go 22".
