    Hello, got a barreled action on the way, just looking for some load date. So far I have some nosler brass, and nosler's data for the 280 AI,

    Where else can I find some load data, starting loads in particular? I'm comfortable in my reloading to work up to a safe load (and accurate, I know when to back off) but I have always relied on starting "recipies" I'm not so experienced that I feel okay with just picking and choosing components.

    For bullets, I'm looking to barnes, nosler, but not limiting it to that, I'm going to use some nosler data to break in the barrel but dont want to be limited to nosler.

    For those you shooting it, any advise, or some resources I've not listed? Really want some published loads to be safe and efficient in my shooting.

    thanks for any help you can give me!!

    Data from the Guns and ammo August 06 by Chub Eastman.

    Hornady IB 139gr, imr4350 57grains, fed210m, 3,078fps, 53,700CP
    Nosler BT 140gr, ARel 19 60 grains, fed210m 3,054fps, 52,000CP
    Swift Scirocco II 150 gr, H4831sc 60 gr., WinLR, 3,053 fps, 59,000CP
    Nosler AB 160 gr, AA3100 58 grains, Fed210m, 2,845 fps, 53,900CP

    I usually start with the max loads listed for the 280 rem, and work up shooting over the crono and checking for pressure signs. If you meet or start exceeding speeds of the 7mm rem mag you would be very wise to back off!

    I have found H4350 to be a little too fast for my 280ai. If you don't mind using Alliant powders Reloeder 22 works very well. I have also had good results with H4831sc and H1000 with heavy bullets.

    Hope this helps.

    I have a 700 blueprinted action with a Hart #5 flutted 24" barrel.
    I fireformed R-P brass using my favorite 280 Rem load, 140 gr BT and 57.0 grs RL19. After about 100 rounds, things began to shape up.
    Usig a 160 gr AB, RL22 is the powder to use.
    I am currently using Nosler brass with 60.0 grs RL22. Accuracy is steller.

    I am reloading for my 280 AI and have found that H4831sc and r22 give the same velocities per grains of powder for the 160 accubond in my gun. The reloader 22 groups a little tighter most of the time but it is very close. I have went all the way up to 62 grains of powder and the bolt opens easily and the primer is rounded so the pressure is not extreme but I am not going to go any higher.
