The 338 WBY RPM (Rebated Precision Magnum) is based on the Weatherby 6.5 RPM necked up to accept a 338 caliber bullet. The 338 RPM was designed to take advantage of Weatherby 6-Lug action to get magnum performance in a 5lb rifle. The large body diameter, low body taper, and 35-degree shoulder mean that case capacity is greatly increased, leading to higher velocities.

My Backcountry TI is awesome. It loves the 185gr Barnes and Iโm happy with that. Lille is right at 6lbs with Swarovski Z5 scope. Talley rings and bases. Gun has great balance and is a pleasure shooting it with brake. I got 24โ barrel and Iโm not sorry I did. More velocity and harder impact. I would recommend!

I own the backcountry 2.0 with the 18โ steel barrel. I love this rifle, it is now my go to rifle.
The 338 is super efficient and with the break and amazing stock it has the recoil of a 30-06.
My rifle loves the 185gr Barnes ttsx
