25-300 Winchester Magnum
We built this rifle on a Remington 40X action. The barrel is a stainless steel from Dan Lilja, finished at 26". A Leupold 6.5-20 scope was installed in Jewel rings, on Kelbly bases.
The 75 grain Hornady, 85 and 100 grain Noslers were molly coated. The Speer and the Barnes X bullets were not. Winchester brass and Winchester WLRM primers were used in all the following loads. All groups were 3 shots at 100 yards.
