Would someone with QuickLoad mind running this for me? I've done some digging(here and elsewhere) for this bullet/powder combination, and while I've got an idea of where to start and what max pressure may be, I'd really like to have as much info as possible before I start loading and slinging these downrange.
162 ELD-x
RL26
9 twist - 26"
Nosler brass
CCI large rifle primers
Much thanks.

I'm interested in this as well. I'm guessing 60 gr for 3000 ft/sec at 63k psi................

Some info from another forum. https://www.longrangehunting.com/threads/280-ai-with-hornady-162eld-x-load-data.175587/I am liking R26 and the 168 LRAB in mine, haven't tried the ELD-X in 7mm yet. Worked well in 6mm.

There's also some actual (not computer-simulated) rifle-tested data for the .280 AI in the BIG BOOK OF GUN GACK II. It's from a 22" barrel, but adding 100 fps would come close.

These are my loads from a 280 Ackley 700 Ti, 22" barrel.
Hornady 162 ELD-X
Win Primer
Nosler brass
RL-26 61.0 grains

3,065
3,074
Accuracy was great but I ended up dropping .5 grain.

These are close to mine but I dropped back to 59.5 grains as I was testing these at around 100 degrees. This with the 168 LRAB. Have not tried R26 in my 7RM yet but the 280AI is beating it with R26 with 2" more barrel. I suspect I can get to 3,100 in the 7RM even with it's 23" barrel and R26.

Twist and primer make no difference in Quick Load. Adjusting for variance in brass requires the internal H20 volume. I ran this with the default case capacity provide by QL:
Cartridge : .280 Ack Imp
Bullet : .284, 162, Hornady ELD-X 2840 G7
Useable Case Capaci: 63.427 grain H2O = 4.118 cm³
Cartridge O.A.L. L6: 3.330 inch = 84.58 mm
Barrel Length : 26.0 inch = 660.4 mm
Powder : Alliant Reloder-26 *C
Predicted data by increasing and decreasing the given charge,
incremented in steps of 0.781% of nominal charge.
CAUTION: Figures exceed maximum and minimum recommended loads !
