Anyone used the the 7mm 150gr ELDX bullets in there 280 AI? Just got a box from Cabelas and checked my Hornady book and I don’t see any data for these bullets. Any help or hunting experience would be great.

Just use the standard A-Max data, and bullet weight and you'll be fine, or any other lead core copper alloy bullet weighing 150 gr.

Just stay within the expected velocity range for that weight, and barrel length you're using.

Just remember that some types, like partitions, boost pressure and have a lower max charge than other cup and core bullets of the same weight.

Hornady manual 10 has loading data for 280AI with 150gr,162gr and 175gr ELD-X.

I just was testing the 162 ELD-X in my Jarrett 280 AI in the last few weeks, and what I noticed was these bullets shot best in my gun right at the lands to +.020" touching vs. going away.

That said I felt these wouldn't stabilize well enough since my barrel is a 1:10". I did run them out to 700 yards while fire forming some RWS brass and was surprised they performed as well. You might have better luck then I saw, but try H4350, or IMR 4831 both of those showed good speed in my rifle w/the 150-160 grain weight bullets. RL-22 had the most velocity, and worked well with the 160's.
