L.E. Wilson 7mm PRC Chamber Type Bullet Seater Die BS70-PRC

Description

L.E. Wilson has built chamber type seaters for a long time, and this 7mm PRC version carries the same reputation that made their inline dies a staple on precision benches. Rather than relying on the case and bullet floating into rough alignment the way a conventional threaded die does, this one captures the case inside a cavity that mimics your rifle's chamber. A close-fitting seating stem then pushes the bullet straight down into the case mouth. Everything is held in alignment before the bullet ever moves, which is why these dies are known for low run-out and consistent cartridge overall length round after round.

What Sets the 7mm PRC Chamber Type Seater Apart

The big difference here is control. Because the case and bullet are both captured before seating, there's very little room for the bullet to tip or seat crooked. The fit between the stem and the die body is tight enough that you can draw a slight vacuum, which gives you a feel for just how precise the machining is. For 7mm PRC loads running long, heavy, high-BC bullets, that straight-line seating is exactly what helps tighten groups. This die is now made of all stainless steel, so it's built to hold up over the long haul.

Running the BS70-PRC on an Arbor Press

This is a hand die, meaning it's designed for use with an arbor press or a mallet, not a conventional reloading press. Seating depth is adjusted with the standard seating stem, and the included seater base elevates the loaded round so the primer never rests against a hard surface during seating. It's a favorite setup among benchrest, F-Class, PRS, and high power reloaders who want to walk their seating depth in and feel every bit of the process.

Proudly made in the USA, the BS70-PRC is a straightforward, purpose-built tool for anyone chasing accuracy with the 7mm PRC. Pair it with an arbor press and you've got one of the most consistent seating setups you can put on a bench.
