.280 ackley build

I have a Shilen #5 1:9 .284 barrel on the way(3-4 months). It will be reamed out for the .280 ackley. I am having it put on my model 70 extreme weather .30-06. I plan on having somewhere just short of the velocity of a 7mm rem mag since I have a custom built 7 mag with a 26 inch tube and don't quite need the same ballistics of that rifle. I am not familiar with the ackley but really impressed with what I've read and am excited to try it out, especially since my model 70 holds 5 in the mag vs. 3! So my question is, "at what length should I have the tube shaved off at to achieve good velocity without going too long?" I was thinking 24" would be appropriate but I just don't have any experience with this setup. I will pry be running a 160 accubond through it if that helps.

Re: .280 ackley build

When I build mine it will have a 26" finished length barrel on it.

Not sure on the 24 vs 26 velocities....Wish I could help more. Hopefully some others can chime in to help.

Re: .280 ackley build

Well that is always an option since the barrel will be shipped at 26". What kind of velocities are you getting? and what grain bullets are you shooting?

I don't have one yet.....I have started my build, but this is all I've got so far...



New stainless Remington 700 action, and a stainless PTG 0.200" recoil lug.

I still have to order my barrel, stock, bottom metal, and get the cash to pay my smith for labor.

I plan on going with a Rock Creek 5R 1:9 blank, finished out to 26".

I handload, and will be mainly shooting Berger VLD 168 bullets. But I also plan on working up loads for the Berger 180 VLD's, and for the Nosler 160 Accubonds.

Re: .280 ackley build

It doesn't need 26 to get full burn of the powder like a RUM type cartridge. Depending on your desire to make the rifle a bit more "handy" and keep over all weight down I would go 24". I have a Dakota in 24 and a Red Hawk Rifle due to be shipped any day in a 24. Most 7 Rem mags are 24 and you should get within 100 fps of the mag.

Re: .280 ackley build

Seems to me everyone is running a 1:9 so I feel pretty safe there, that's good to see. I also handload but will probably save up some nosler ackley brass from the get go by shooting factories for a while. I plan on sticking with the 160 accubond though once I get around to it. I like the accubonds and had good luck on deer with them in my 270wsm. rharfo, if you think I can get those numbers with a 24" then that's pry what I'll have it cut to. That would split the difference nice betweer a long 26" and a 22" barrel. Thanks for the info guys, and good luck with that build MudRunner.
