OK I was wondering - I shot one into a gallon jug with a mixture of sawdust from the radial arm and water. Mixed the two together to kinda a uniform solution. I placed it on its side on top of perfectly good white plastic bucket at 80 yards.

Then I took the shot at it I expected the bullet to punch right through the jug but I never expected the amount of pressure it created on the way through. It appears it created nearly equal pressure all the way around the jug. It was quite a rupture, enough that it even broke the out the bottom if the bucket. When walked out to the scene I was totally surprised how out from the target it through portions of the solution. And this was only a .452x250 grain bullet. The 458x260 even has larger and deeper flute to create more pressure.




Even though it is a non-expanding bullet it will get the job done - more than one might expect.
