Weak, very little knock down power, 7mm Mag is ashamed of its little bitch arse cousin. Far inferior to the GOAT .280 and my second choice, .308. WEAR YOUR HUNTER ORANGE guys, and hunt safe!

It's all about shot placement

HaHa!! Touche'

Guy gave me a box of bullets labeled 280. But he's wouldn't load. Read on the box that it was 7mm express compatible. Had to look that shite up

Nope. Different bullets. 280/ 7mm Express on left and 280 on right





From what I gather, after 1979 Remington started making 700s 280 suitable for 7mm Express

I hear ya. The cartridge you have on the left in your pic is the AI. Here is a photo I found online. Looks identical.



They brought the neck up on the AI to allow for more powder to amp it up a bit. If you don't mind, do you have a picture of the box that the ammo on the left came in?

That box is for the ammo on the right in your picture though. Do you have the box for the left one?

And FWIW, I'm not trying to prove you wrong or anything with this. I'm just always interested in this kind of stuff, and if I learn something new, that's awesome.

In your picture, I'm assuming that you were having an issue getting the bullet on the left to load properly?

I thought 280/7mm express has always been the exact same round you have in your hand?

What you have there is a .280 round vs a .280 AI (Ackley Improved).

Correct, Fratigerguy. In FelicanaTigerfan's pic, the loaded ammo on the right w/ the lead tip bullet is the 280 Remington (AKA 7mm Remington Express); the loaded round on the left, w/ the red plastic tip bullet, appears to the a 280 Remington Ackley Improved.

P.O. Ackley was a famous gunsmith who had an entire line of cartridges named "Ackley Improved." The basic premise of the AI cartiridge was to take a factory cartridge and increase the powder capacity, thereby increasing muzzle velocity. The process to increase powder capacity is called "fireforming" and is done by changing the configuration of the brass by reducing the taper on the sidewalls of the brass and making the shoulder angle sharper; as a consequence the neck and brass overall length are shorter. Looking at the AI load on the left, the faint, horizontal line just below the shoulder is the location of the original shoulder. Up until recently, AI cartrideges were a handload only proposition, but Nosler now loads some. Regular factory brass is usually used to make the AI brass. Hence the headstamp on both rounds read "280 Remington." The round on the left is clearly not a Remington factory load as the primer is silver, not gold colored. One of the easiest ways to "fireform" brass is to shoot a regular factory load in an AI chambered gun. OTOH, you're correct in that an AI load/brass will not fit in the regular factory chamber. I suspect someone loaded 280 Remington AI ammo and put it in the the ammo box w/o changing the label. 280 Remington, 7mm Remington Express or 289 Remington Ackley Improved are ALL excellent hunting cartridges.

Here's an article comparing the 280 Remington vs the 280 Ackley..
