Sent four down the pipe at a earthen berm today to see how the recoil it felt.
As
@Hank2211 says, it is not a caliber to use for plinking.
At 180 yards the dirt clods flying impressed the bystanders. I offered to let anyone interested take a shot. No takers! It seems the close up demonstration of the recoil created an impression as well.
It is a step up from the 375 H&H for sure. Not quite a .450 Rigby, but pretty darned close.
I think I may need to add a couple of spacers for some extra length of pull. My thumb seemed to want to visit my lip for some reason.
The next trip I'll actually take a target along and see if I can actually demonstrate some accuracy.
