[QUOTE="Fiftydriver, post: 588644, member: 10"] I would personally go with the old true Ackley Improved as it will be easier to get dies for in most cases. I am not a huge fan of Nosler brass. IN my opinion, way over priced for what you get so I would just form your own brass. For this type of rifle 50 rounds of formed brass would be plenty, I would never form more then 100 rounds for a long range rifle, no need. Performance wise, you will be right at factory loaded 7mm Rem Mag performance levels. Many say that the 280 AI will fully match the 7mm Rem Mag. This is not true. This is because a properly loaded 7mm Rem Mag will easily match a 7mm Weatherby Mag which is generally loaded a full 100 fps over the Rem Mag, why, I have no idea as the Rem Mag actually has slightly more case capacity. You just have to be careful when working up loads, NEVER USE 7mm WBY data in a 7mm REM Mag. Back to the 280 AI. Loaded safely, it will come very close to matching "FACTORY" 7mm Rem Mag ammo specs and do so with around 8-10 grains less powder. It truely is a great chambering as long as you go into with realistic expectations. Shoots very accurately, even fireforming loads generally shoot quite well. Long barrel life, great performance on big game. Probably one of the very best chamberings based on the '06 parent case. [/QUOTE]
