[QUOTE="Trickymissfit, post: 451886, member: 25383"] The way to start out is with a single shot Savage action. The short one will handle the 57mm case length just barely. The Savage is a little longer than the Remington 700 action (I think it's about .150"). The advantage you'll see is in bullet selection, and making them fit. There is no actual SAAMI data on these two cartridges, and using the Remingtion magazine will not do you much good here. Go with a single shot Savage for the slightly longer action length. (also shoots slower giving the barrel a breather) The 6/.284 is a barrel burner just like the 6.5/.284. The velocity difference between the 6/.284 and the 6mm AI is nill. You can fireform cases with factory loaded 6mm Remington ammunition (you will see a tiny bit of shrinkage). You can't do that with the 6/.284, and necking 6.5/.284 brass down and foreforming will become a chore. I think a 70 grain bullet at 3650 fps out of either one is about it (The 6AI will hit about 3725 fps at about 52K psi in the chamber). There isn't a lot data out there on the 6AI, but Ackley says it will do 3750 using 4064 powder. Huntington claimed 3800+ using 4320 and a 70 grain bullet. I've never known a single person that built a 6/.284 that kept the chambering, but do know a few guys that have shortened the .284 case and been very happy with it. But of course if you really wanta have a fast 6mm, you can go with a 6mm Vias. This case works very well in a short action Remington and will push a 70 grain bullet in the 4000 fps area gary [/QUOTE]
