It's a physics problem of ke or momentum, but the equation doesn't hit me yet.
Would need to know the mass of the ram, and the point of impact, need the thickness or depth of the base of the ram also (ie, front to back measurement at the base), ht may might be helpful.
Takes less ke to "knock it over" when hitting the top than when hitting close to the bottom.
GF:
I went to a physics site and used a calculator they had that gave different measurements of mass. It is legit.
I am not sure if flbs/s is the right answer though.
They shoot for legs and high shots when using the light stuff I think. Given ZE's competition allows every target to be shot from the prone using bags, rests, et. al, shot placement becomes something more than an excuse for failing to bring the right tool for the job. I still think a 30 grain capacity case and a 6.5mm bullet is not the right combination for the job here but I would try the 140's before going to something I know will work like a 6.5 CM or 7.62.
