[QUOTE="J E Custom, post: 1718752, member: 2736"] In order to fire 280 rem factory ammo, the chamber needs to be done like the article Deputy posted. Using a 280 rem go gauge and cutting the chamber .004 thousandths short to compress the round slightly for a good fire form and accuracy. If the chamber is cut to the "NEW" SAMMI spec. it can be as much as .018 deeper and can cause case head separation. the new 280 AI SAMMI chamber should only be fed Loaded ammo for this chamber. The "Old" Ackley chamber can handle all 280 Remington ammo safely. If you don't reload, the new 280 AI ammo/cases are what You should use. If you re load the old AI chamber will allow you to use any 280 ammo without problems. If chambered correctly the "Old" AI can be very accurate while firing the 280 ammo. Some have been using both sizes of ammo in there chamber and say it will work, But the chamber dimensions tell me that it won't without some problems. I personally like the flexibility and convenience of using any 280 ammo and getting good accuracy while fire forming. Just My Opinion J E CUSTOM [/QUOTE]
