280ai /Berger 168VLD load data

[Mcarso1]

Trying to get a good starting load , none of my books have 280ai. I was going to start off in the middle of 280 load info but thought I would run it by you guys who are using the 168 VLD. I have Peterson brass, federal 210 and 215 primers and the only powder I can get my hands on is Retumbo and 4831sc. Any help would be appreciated!

Hodgdon's lists Retumbo load data for the .280AI as follows: 168gr bullets starting load is 59gr and max 63gr. I prefer large rifle magnum primers in my .280AI using slower powders. I use RL26 for 168gr VLD's with very good speed and accuracy. Curious to see how Retumbo works for you. Keep us posted. Thanks

I ran QL for both Retumbo and H4831SC. Retumbo is too slow as it requires a 16% compressed charge of 69.5 grans to get to max pressure. A 100% fill rate only gets to 2551 fps.

H4831SC data is attached.

H4831sc is a great powder for the 280ai, won't get you the speed like rl26 but it's very consistent and accurate.

I get about 3030 with Peterson, 64.8gr Retumbo, CCI250, and 168 CH. Compressed load but very accurate. 25" barrel.

168CH. What is the CH? Thanks.

Classic Hunter. Those shoot better in my gun than the VLDs so that's what my gun gets fed.

58.4g H4831 same for the 168 vld and classic hunter.

FWIW ….. I have a .280 Remington, not AI; from the Sierra book, 44.4 of Reloader 15 with a 150gr SMK. It holds the X ring at 600 yards. HTH

Nosler's site has 280 AI data. Nosler bullets, of course, but it will get you close.

Nosler manuals 8 n 9. Not sure how helpful seeing what these guys are doing. LolView attachment 405770

My load for the 280 Ackley is 60 grains H4831SC, PETERSON BRASS, CCI LR MAG PRIMERS, 10 thousands jump with the Berger HVLD 168. I'm 2950 fps. My chamber isn't Sami, I had it cut long because I also shoot the Hammer Hunters 155 and they are long, I tried for the 169 hammer Hunter but they wouldn't shoot as well as the 155 hammer Hunters. I'm in California so I spent more time with the 155 hammer for hunting.
My buddy has a rifle built by Dallas Lane and his load is 59.5 of H4831SC WITH NOSLER BRASS, CCI LR MAG PRIMERS, HE IS AT 3050 fps. Please don't start at these I looked at the post before me and they said they are near max load.
Hope this helps,
Jason

I have no experience with retumbo. So I can't help there. But all I run in my AI is H4831sc. It's a very consistent powder in ALL temperatures. Not a hot rod, but no slouch either.

I'm running 59.5gr of H4831sc with 162 eldx. Went to around 61-62 grains before I had pressure. Settled around 2900 as it is just over quarter inch group on multiple occasions. Plenty for my uses. I'd start around 56-57gr and work up if I was doing it again. Good luck with your AI. I love mine. It's usually the rifle I go to.
