That's into top end 7 mag territory according to Hornady's manual. Better check that Chrony against an Oehler . . . . . I never thought I'd grow up to be a grumpy old man, but I did, and I'm killin' it.

Anything of about the burn-rate of H4831 will do it, even in a 22" barrel. “Montana seems to me to be what a small boy would think Texas is like from hearing Texans.” John Steinbeck

NOTE: R26 wasn't around when I was doing this. Neither was R25. I built two test rifles in 280 which were turned into 280 Ackley's. I wanted to compare the two using the same barrels. My loads were tested by a guy who developed the data for Speer's manual. At the same pressures the AI's gained about 40 fps over the 280's. The standard 280's fed thru the magazines much better which I valued more than the 40 fps. A lot of 280 data is pretty wimpy and a lot of 280 AI data is pretty optimistic.

My calculations indicate a possible gain due to powder room of about 50 fps, very similar to the 40 fps you cite. The big difference between the SAAMI .280 and .280 AI is pressure. The .280's maximum average pressure is 60,000 PSI, due to it originally being chambered in the Remington 740 and 760, along with bolt-actions. The .280 AI's SAAMI MAP is 65,000 PSI, which adds a lot more to the velocity than the small increase in powder room. As I hinted at earlier, with the standard .280 loaded to 65,000 PSI it's pretty easy to get 2900 with 160-grain bullets--or at least most 160-grain bullets--especially from a 24-inch barrel. The .280 has a small but definite velocity advantage over the .270 Winchester, due to its larger bore, and Hodgdon's .270 data from a 24" barrel shows 2843 fps for the 160-grain Partition at 59,800 PSI. The Partition is one of the bullets that produce more pressure than most, probably due to the obturation of the rear core sealing the bore a little more. AccuBonds result in less pressure, due to a shorter bearing surface. The last test I ran of a .280 was in a 24-inch barreled Sako A7, and with published data got these results: 156 Norma Oryx, 55.0 Alliant 4000 MR, 2956 fps 160 Sierra GameKing, 61.5 Magpro, 2994 fps 168 Berger VLD, Norma MRP2, 2924 fps. Would be pretty confident of getting 2900 with the 160 AccuBond, even in a 22-inch barrel. “Montana seems to me to be what a small boy would think Texas is like from hearing Texans.” John Steinbeck

The 270's great advantage is that it is readily available everywhere that has big game to be hunted. Funny, I recall that your first modern custom was a 280. That was a nice rifle. I will wager that nothing you have used since is a big jump in performance on anything in NA or for African plains game. “Perfection is achieved not when there is nothing more to add, but when there is nothing left to take away”.

Always liked the 280 Remington but it was hard to find in left hand rifles so I went to other rounds, still would like to try one or maybe a Tikka in 7x64. Two of my friends hunt with the 280 Rem so I have gotten to do a bit of loading with it, one uses 160 gr Partitions and the other the 175 gr Grand Slam. Judging from all the posts here about RL 26 and the 270 Win, it should be equally good in the 280 with 160's and heavier especially. Gerry.

Still pretty cool though! That's right there with my 7 WSM/162's. The CENTER will hold. Reality, Patriotism,Trump: you can only pick two FÜCK PUTIN!
