Has anyone been able to get 3000 fps in the .280 Ackley Improved in a 24" bbl. and shooting 160 grain bullets? I had one years ago. Sold it (big mistake) and now I'm thinking of building another, but curious whether 3000fps with a 160 grain pill is attainable. TIA

That's what I'm thinking, but it'll be close.

I’d have to look to be exact but I’m in the 29’s with H4831sc and 168 Bergers

I would think it could be real close. My hunting load is 140gr at 3140 fps.

Re 26 and Re23 will both get you there.

It boggles my mind why so many think that 3000fps with large grain bullets is so important. Pushing a large grain bullet anywhere over let’s say 2850fps will do the job within 500 yards. What needs to be important is accuracy, bullet placement and follow up shoot if necessary.
I had a very accurate 280AI in a Remington Sendero, PACNOR bbl., platform. It shot bug hole groups at 100 yds. Sub 1” groups at 200 yds. It performed excellent with 160 Accubonds that I dropped a Scimitar Horned Oryx at over 200 yds. plus. It chronographed this load at just over 2850. The weight retention was massive and deadly. Not once did I desire to pushing this load over the 2850 plus accuracy load. Dead is dead and never had any complaint about not being dead enough. Accuracy first, bullet placement second and prepare for a follow up shot if necessary. MTG

Mine is running 3025, however that’s not as important as the BC that bullet has..

Some of these loads sound/are very hot.....
I'm running a 168 at 2,820. It's warmish. MV is a cool thing to share with your buddies but the impact velocity is what should be paid attention to....

When I go to H4831SC I drop about 100 FPS with same bullet but groups tighten to .5.

Mine with R26 and a 25" barrel runs right at 2,950 fps and is darn close to my 23" barreled 7RM. I have not tried to go higher as R26 doesn't show conventional pressure signs until you are really high up there. Mostly I am using 140s at 3,200 fps in the AI.
For years my 175 7RM loads were only getting 2800+ fps and they killed things pretty well.

Mine has a 25 inch barrel and hunting load is a 140 Accubond at 3200.
I'm using H4831SC.
I would say you should be able to get there

I’m getting about 2915 out of a 26” ridge line using 58.5gr H4831sc. No pressure at all and I’m confident I could push past 3000 but it just shoots so good, I don’t want to mess with it.

27" X caliber bbl
9T
formed from Lapua '06 brass-tough brass
175g Nosler LRAB
Fed 210
58.5g of IMR 7828
2900 fps
tiny clover leafs with all bullets over lapping
I can not say enough good about this bullet in how it kills, penetrates from all angles
This bullet took less than 20 rounds to tune on the load, seated .010 off the lands
On my old Rem 700 with a 24" factory barrel
58.5g of 7828; fed 210
160g-162g
2930 fps
Rem brass
AMAZiNG accuracy!
350 and under I use a 160g Sierra btsp-deer do not walk away
The 162g SST is a MUCH tougher bullet than you would ever imagine
In another rifle, I am running 180g eldM's- buy 10 boxes if you can.

https://www.24hourcampfire.com/ubbt.../11470108/Testing_RL_26_in_the_280_ReminI started with this info to work up my standard 280Rem (not AI) load. It's a Ruger M77 MarkII, 22 inch barrel. 60.5gr RL26 under a 160gr SGK gives me 2975fps. I would think out of the AI version, 3k should be easy.
Those who must raise their voice to get their point across are generally not intelligent enough to do so in any other way.
