280 AI load data?

26" 1:9" Proof Sendero Light
Nosler brass
CCI BR-2
58.0gr RL23
175 Berger Elite

SD 5.6

START LOW, work up slowly. Not quite max load in my rifle.

Dude, that's screaming in a 280 AI!!! That's what I'm getting for the 175 ELDX in my 7 STW, and that's with 17 gr more powder!! I couldn't reach the next velocity without being over pressure.
I'm impressed

RL23 will get you there I believe 100% what Lance is getting with the 175's.
I got 3240 in 1 280AI and 3220 in another with 24" tubes and .5 m.o.a or better with 140's

Yeah, it is moving pretty good. Not my absolute max, but getting close. I barely get any more in my 7RM w. 180 Hybrids.

+1 for sure. Lance got me started and my current node with a 24" barrel and the 175 EH is around 2830. If I can ditch all this work travel I just need to work on seating depth.

IMR 7828 with 168-175g bullets with fed 215's is unbelievably accurate and fast!

Start at 56g and work up in two shot groups, but barely off or touching the lands.

Expect tiny groups.

Wow!! From my research, I was expecting to get 3100-3150 fps from the 140's.

Any suggestions for a starting load with the 140 Accubond with RE23 or 26?

I get 3200fps with a 140 accubond using h4831sc and just got a load for 160 accubonds going 3060fps using reloder 26

I tried the same powder and hit max at 62.0 grs. with a 26" barrel. Don't know my velocity as my Magneto bit the big one. Is my load anywhere yours? Just wondering for a velocity guess.

I hit 62.5 of h4831sc with 140s and I think it was 61.5 of reloder 26 with the 160s

Also interested in a starting spot for RL23 and 140 accubonds.
