What are Ackley Improved cartridges?
The Ackley Improved family of wildcat cartridges are designed to be easily made by rechambering existing firearms, and fireforming the ammunition to decrease body taper and increase shoulder angle, resulting in a higher case capacity.
What is a 25 06 Ackley Improved?
25-06 improved worth the work of forming cases and handloading. The heavy rifle shot three-round groups between 1.5 and 2.0 inches at 100 yards with the case forming loads. The first bullets hit somewhat low at 100 yards.
Who invented the 280 Ackley Improved?
P.O. Ackley
P.O. Ackley, who designed the . 280 Ackley Improved, was well-known for improving standard factory cartridges by simply opening up a typical SAAMI spec chamber to have less body taper and a much steeper shoulder. This created a larger, more efficient propellant chamber.

What are the ballistics of a 25 06?
The combination of high ballistic coefficients with high muzzle velocities give the . 25-06 a very flat trajectory as well as retaining kinetic energy down-range. The cartridge is capable of propelling a 117 grain (7.6 g) bullet at up to 3,200 feet per second (980 m/s) and energy levels up to 2,500 ft⋅lbf (3,400 J).
What is a 280 Ackley improved compared to?
280 Ackley Improved loads that either match or exceed the performance of the 7mm Remington Magnum and still have less recoil. However, the 7mm Remington Magnum is still capable of greater velocities overall. Barrel length is another thing you should keep in mind.
What is a 280 Ackley Improved good for?
280 Ackley Improved is the steeper 40 degree, which lengthens the case body and allows for about 5 percent more powder capacity. This sharper shoulder can also increase case life, which is a good thing for the handloader.
Is 280 Ackley Improved accurate?
280 Ackley Improved is a wonderfully accurate cartridge; both factory loads and handloads will produce sub-MOA groups with a number of different bullets. However, it was Nosler who, in 2007, brought the cartridge to SAAMI for approval and commercial production.
