It is not that i do not think that 1400fps is not enough, because 800 has been shown to work also... the only point that i was trying to make is that you may be setting limits on yourself for a humane quick harvest. along time ago i shot a big bull three times with a 308 using 180 grain bullet... all three shots were in the chest cavity but in the first two shots the bull stood there never moved never flinched.... after the second he turned and started trotting off that is when he got the third. 120 yards later he piled up in the creek bottom - He was actually dead on the first shot I just did not know it and he gave no sign that he was even hit.

From that time on I always professed that the bullet needs to cause enough internal shock and trama to devastate the animimal on the spot - everytime... not just sometimes..

In that same decision I made the choice that I wanted to be over prepared vs under or marginally prepared.

I agree the 250 Thor from a ML will work if you use it within its limits. For me i would like to have a bigger margin of error, but that is just me.
