Here ya go. All default settings. I used 140 gr Accubonds since you didn't specify what bullet you're planning on using. I can run another one with a different bullet if you let me know.

Cartridge : .280 Ack Imp
Bullet : .284, 140, Nosler AccuBond 59992
Useable Case Capaci: 66.302 grain H2O = 4.305 cm³
Cartridge O.A.L. L6: 3.330 inch = 84.58 mm
Barrel Length : 24.0 inch = 609.6 mm
Powder : IMR 7828 SSC

[muzz]

Damn im not shooting very fast. Thank you for posting that for me. I was hoping for faster velocities.

 

[M7025-06]

No problem.

What kind of velocities are you getting?

 

[muzz]

not sure yet, just working up some loads to get the groups then ill shoot through my chrono. I would like to get as close o 3000fps as possible

 

[M7025-06]

It looks like QL sets the default max pressure at 58,700 psi, which I didn't notice til now. You should be ok to work up to 270 win pressures (65k), but as always, work up slowly & watch for pressure. Hitting 3000 fps should be easily doable.

My opinion...IMR-4350 is probably gonna be a little high on the burn chart to get the most out of a 280AI. Stick with slow burners (H-4831, R-22, IMR-7828).

 

[MAinAR]

RL 23 or even RL 26 will be hands down better powder.....in 24" i would think MRP at about 64grains or RL 26

Run it again with MRP, RL23 or even RL26 for 24" barrel with 150LRAB????

viewtopic.php?f=4&t=30225

 

[Dwh7271]

MRP works well in my 280AI fwiw.
RL 22 is good also. JD338 has a heckuva load in his with 22.
Have some RL26 on the way. Have to play with that too.

 

[MAinAR]

I would expect to see 3,150 in the 280AI with 24" barrel with RL 26 at bout 64-66grs with 150LRAB

 

[muzz]

MRP and reloader 23 and 26 is what I want to try but there is none around where I live. Mrp is the one I was really hoping to get my hands on.

 

[MAinAR]

MRP and reloader 23 and 26 is what I want to try but there is none around where I live. Mrp is the one I was really hoping to get my hands on.

You will see large difference when you do, i would lean to RL26 with the efficiency of the 280AI.

I made trip to store today and bought 8lb of RL26, having tested it a lot in 7RM it looks like prolly the best advancement in a long time for slow burn rate powders. Been using MRP for a long time and it is occupying back shelf as of now.

 

[M7025-06]

I haven't bought the latest QL update so I won't have R-26 available to run for ya.

 

[muzz]

I will see if I can get some, Is there load data out for rl26 and 23?

 

[MAinAR]

I will see if I can get some, Is there load data out for rl26 and 23?

Not for the 280AI but FOTIS has been large help to me with running QL!! The link I posted earlier is notable in that RL26 is acheving 100% burn as low as 62grains or so in the 280AI.....

Take that data and pull off difference in 24 and 27" barrel. Pressures won't change a lot.

Watch for a post from me if I get some powder, I might have a lead on some RL 23 and Rl 26. I think ill get a pound of both. If no 26 would 23 be good to go with?

I have shot both alot and RL26 doesn't hit the wall on pressure like the 23 and is bout 125fps faster across the board. Seeing RL 23 make about 50psi per grain more pressure than RL26.

You will see all the ATK family (Federal Premium) ammo loaded with RL23 and RL26! This is gonna be from .243 to big big boomers.

I just have to see what happen with RL26 when temps get over 80 degrees....!!!!

Will get hard to find then!

well there claiming there temp stable aren't they?

Yes, saying that RL23 is flatline stable as RL17 and to expect RL26 to be at 0.5fps per degree change from 68 degrees, been tested from 0 to 125 degrees, but I remember when the "H" powders had large claims also, so in a year from now we will KNOW!

But RL26 has been awesome for me on accuracy and "predictable" velocity and I have a lot of faith in pressures when a powder is predictable on speed!
