Interested to know if anyone is shooting one of these 5 LB guns in any of the hotter cartridges like 300 Weatherby, 338 RPM etc. With the new recoil pad and brake I would think they are fairly manageable. My question is more about what they are like when you put the thread protector on instead and shoot them that way. The 338 RPM with the 18" barrel puts up some pretty stout recoil numbers even just using 200 grain bullets at 2800 fps. Makes 37 ft lbs of recoil, assuming a hunting weight of 6.3 Lbs with scope and sling. and a recoil velocity of almost 20 FPS.
