Thanks for the tip. My only issue with RL23 is case fill. I don't have enough case capacity without significantly compressed loads. StaBall6.5 may be the ticket.

I shot my 280AI this morning with h-4831 and was getting 2,750 using 55.2 grains of powder. I was also shooting 168 bergers.
I have tried in the past shooting h-4350 and got it up to 2,900 FPS but didn't like the accuracy compared to H-4831.
All loads were using Peterson brass.

H4831 and a 280ai just flat out work even tho it's on the slower side there's no denying the accuracy
I agree that H4831 works very well in the 280ai. However, that 150 gr BD2 is a long bullet that has a profile that doesn't allow it to be seated very long in a SAAMI chamber. Actually I have never tried Sta Ball 6.5, but ordered a couple of lbs and will pick it up tomorrow. I'll try to find the time to load up one round ladder per Nralifer's suggestion and see where I get pressure. Then depending on results load some up for groups.
I've heard people having good luck with sta ball powders!
Please share your results.
Please share your results.
Hopefully the rain will hold off tomorrow. Loaded up a pressure ladder with the Sta Ball 6.5 and few HH143 with H4832SC and H4350 to hopefully find a good node. I'll post the findings.
Why three different bullets with three different powders?

Interested to see what you get with those BD2s I got RL23 on the way and I'll be sure to post results when I can get to the range
I have a decent load with AB160 and just took a pic next to the BD2 and HH143 for reference. I'm still trying different loads just experimenting. I keep buying different powders and bullets because I enjoy tinkering.

A bit out of line, but using the 140 gr. Absolute Hammer and H-100V I'm getting 3,250 fps in my 24" 280 Ackley. Got pressure and heavy bolt at 3,360 and backed off. Very accurate to 200 yds and will see if it holds to 5-600 yds.

Mark…are all 3 of those bullets loaded just kissing the lands in this pic? I ask as COAL looks pretty short for 280AI. SAMMI chamber?
The BD2 is at .025 jump. The 143 is at 040. The AB is at .030. It was chambered with a SAAMI reamer.

Thanks. Having mine throated targeting 0.190" FB to take advantage of using full case capacity while still keeping bearing surface above N/S junction.
Hard to get a sweet spot that works for everything but should work perfectly for 180g VLD, 175g Elite Hunters, 168g VLD, 162g ELDX, and will be very close with 160g Accubond (not sure if long enough to stay above N/S on this one). I will be jumping a fair amount with 140g Absolute Hammers but I hear they are pretty insensitive to seating depth. Anxious to see if it works as well as I'm hoping.
