I'm at 62.0 grs of RL26 with the 160G AB. Nosler brass, 210M primers. Shoots in the .2's.
Pretty close to the same load I’m using. It’s a hammer. I hope it works for you in your rifle. In my AI I’m shooting Remington fireformed 280 rem brass, rem9.5 mag primer. 60.5 gr of R26 and the 160 AccuBond. 25” barrel cooking along at 3065fps. It’s under 1/2” and will fill the freezer fast.

I still don’t own one but I am absolutely convinced the 280 and the 280AI are the most under appreciated cartridges out there.

You probably already have this data, but worth a look. RL-22 is listed.

We fall into the same category on this. The 280 is just great! Much as I like my 7mm Rem Mags... The 280 AI is only a whisker behind them, while burning less powder and holding another cartridge in the magazine. Also no belt to mess with.

The 280 AI has served me well for almost 20 years now. The 140-168 gr bullet weights are in the sweet spot and almost every deer I have shot has been a DRT kill.
I shot this doe a few years ago with the then new 160 gr BT. The rug was yanked out from under her even though it was not a CNS hit.
Fantastic round for sure.

If I could only have one cartridge, you’d have a hard time prying it from my hands. It is my go to.

i couldn't find 26 or 22 so I used RS mag and found excellent accuracy and speed with the 160 Partition in my 280 ai
I love that pic and that rifle! It’s the one that got me started down the 280AI path.

Really like the looks of that laminate stock JD338. I know a bunch of guys went with the 280 AI because of how well that gun works.

I don't have a .280AI but I do have a regular .280 Rem. Not that when Remington brought out the .280, they specified that the pressure be no higher than loads for the 30-06. This was to insure their pump and semi auto rifle would not be damaged. Funnyting is the chamber thse rifles to the .270 Win. and the .270 is loaded to 10KPSI higher pressure than the 30-06. My standard .280 Rem. is loaded to close to what the .270 takes and average velocity id 2910 FPS with the Speer 160 gr. Grand Slam bullet. It's the older two core version which I have a fair supply.
