Time for an update on loads for the .280 Ross.

These data are from the scoped example in my custody, my first .280. Previous results were from the unscoped rifle I acquired later.

Decided to run a sequence of AR2209 (H4350) loads to see how they compared with those from the unscoped rifle reported earlier. Bullet is once again the marvelous 160gr .287 Woodleigh Protected Point. Cases are reformed Norma .300 Win Mags.

52gr - 2590fps
53gr - 2650fps
53.5 - 2675fps
54gr - 2690fps

Just a little slower than the earlier results, but quite acceptable. Plenty of room to add a bit more powder, but for something different I decided to try the slower-burning AR2213SC (H4831), given the case capacity and bullet weight.

58gr - 2615fps
59gr - 2665fps
60gr - 2745fps
61gr - 2785fps
62gr - 2815fps

No case head expansion, rounded primers with no signs of cratering, so why stop there? Unfortunately nearly a year passed full of other huntin',shootin',fishin' distractions before I followed this up.
Results from the range yesterday:

63gr - 2835fps
64gr - 2865fps
65gr - 2925fps
66gr - 2950fps

Big jump between 64 and 65 grains, can't explain why. These are 3-shot averages, rounded to nearest 5 fps, so maybe some room for Murphy's law...

Primers on all these loads were nicely rounded, not flattened into the pockets, but the striker indents on the 66gr loads were showing just the faintest hint of cratering. Might have a slightly oversize firing-pin hole in the bolt-face- must check. Still no case-head expansion, but I'm pretty conservative so that's that for this rifle.

Will toss up some pics of the primers if I can get my uploader working again!

Still pretty stoked that this easily beats any of ADI's published maximum velocities for the 7mm Rem Mag with a 160gr bullet. Happy days!
