Area 419 Funnel Head Features The Area 419 Funnel Head is part of an interchangeable system built to solve the common problems with universal plastic powder funnels including static cling poor fit across case sizes and slow flow on large cases. Sized specifically for the 50 BMG this head threads onto the Area 419 funnel body and is cut to the neck diameter of that cartridge so it holds solidly in place without relying on the case body to secure it. Its bore is machined a few thousandths smaller than the bullet diameter which the manufacturer notes is particularly valuable on large magnum style cartridges like the 50 BMG where flow speed through a universal funnel can be painfully slow. Flutes machined into the exterior are both cosmetic and functional disturbing powder kernels on the inside to keep them from jamming at the neck. Machined from a solid billet of 6061-T6 aluminum the head avoids the static buildup common to plastic funnels which can cause powder kernels to cling to the walls and require tapping to clear. This aluminum construction also makes the head safer for use with black powder compared to static prone plastics. The interface between the head and the funnel body is designed so no kernels can become trapped between the two parts when the head is fully tightened. Reloaders working with 50 BMG and similar oversized cartridges will appreciate the faster more reliable powder transfer this caliber specific head provides.
