Least expensive way to fireform?
I'm getting extremely close to finishing up what has become an 8 year project of building a 257 AI on VZ24 action. As everyone probably already knows, the cost of components, much less factory ammo, is through the roof.
I'd planned on just purchasing some Winchester factory ammo as I've been told through several sources that their +P will last longer than Remington. Unfortunately, I cannot find a store around here that stocks this under rated cartridge, at least the Winchester loading, and the hazerdous shipping charges are high on buy through sportsman's warehouse, midway, natchez, etc.
The one loading I can find around here is the Federal Premium which uses +P brass. Does anyone know about the quality of this brass compared to the Winchester? They're 120 gr Nosler Partition, and being as cheap as I am I can't bring myself to just blow through bullets as expensive as those for barrel break-in and fireforming, so I thought that perhaps I'd pull the bullets and reassemble the loads with 100 gr Remington Core Lokt bullets to make it a bit less expensive.
Does anyone have an easier plan than this? Is there a way that I can fireform factory-new Winchester cases without mounting a bullet and wasting all that money?
I've been watching this forum for quite a while and thoroughly appreciate the collective knowledge of the group.
