[QUOTE="mmacfive, post: 2064361, member: 93205"] The AI gives you about a 4 gr case capacity increase. If one is hand loading the 280 & 280AI to the same pressures (let’s say 65kpsi) the AI will have about a 1% velocity increase, or less than 50 fps. I’ve never had a problem running 160’s between 2950 fps and 3000fps in a standard 280 with brass life near 10 firings. someone on here said that the additional 100 fps is worth it. I don’t think you’ll get 100 fps and if you do that means less than a 75 yard gain. I’m having Melvin Forbes screw on a new barrel as we speak. In a standard 280. But then I also own a 7 STW.....
