404 JEFFREY
Ben Piper Custom: $11,995
Winchester Model 70 CRF


Handcrafted by Ben Piper for the serious hunter and collector: a modern expression of a classic dangerous-game rifle built on a Winchester Model 70 Control Round Feed action. Meticulously finished, precision-tested, and waiting for its first hunt. Beautiful Turkish walnut, buffalo furniture, and precision Lothar Walther accuracy in a stout, reliable .404 Jeffery package — new, never taken to the field, only test-fired to dial in the best loads.
​

​
Why this rifle stands out
This is not a factory turn-key rifle — it’s a thoughtful, custom build that blends traditional aesthetics with modern precision. The Lothar Walther barrel and free-float configuration deliver exceptional accuracy for a heavy-caliber dangerous-game rifle. The case-hardened action, buffalo furniture, and jeweled bolt details give it the presence and finish expected of a serious collector’s piece or a rifle you’d trust on the toughest hunts.
Tested with premium 400-grain projectiles (Swift A-Frame, North Fork 400gn SS, Barnes 400 TSX), it proved reliably sub-MOA — impressive for a stout .404 Jeffery and a sign of careful bedding, barrel work, and barrel/stock harmonics.
Ben Piper built it to be both heirloom and tool — beautiful enough for display, robust enough for the hunt.
