280 Ackley

[Fuzzer]

I am building a 280 Ackley Improved. Looking for load data for the 150g Swift Scirocco. Building for big deer through elk/caribou. Any suggestions.

Jake, For years I shot 140g Ballistic tips
with 64g of H4831.MV of 3150 out of a 24 inch barrel. If you back off some this powder should work fine for the 150g.Also shot 120g BTs with 63.5 of N204 for a MV of 3400.I love the 280 Ackley improved.

Jake,
If you would like to read about some interesting bullets check out this sight

How would you feel about a 130g 7mm bullet
with a BC of .550.

Dave,
Do you knowe of some place where I can find a variety of load info for Ackley Improved cartridges? I am also thinking of having my 25-06 Ackleyed as well. Still wondering. I have Ackley's shooting book, but its pretty limited. Any advice would be appreciated. JS

I am also looking for info on the 280 Improved but I want to shoot the 162 A-Max.

Jake,I believe the last Nosler reloading book has all kinds of data for different weights of bullets for the 280 AI.I would not use the reloading data from Ackleys books,you'll end up killing yourself. I tried for years to beat the performance of the 140g ballistic tip and never could.Please keep in mind this was to 400-450 yards.The BT outshot everything I tried against it out to these distances.This is good performance from a 24 tube in a gun you can carry around. My thoughs are that if you need to run a bullet more than 150g in a 7mm.
Then you need a bigger gun.(caliber)
But thats just MHO and you know what they say about them.
