I have read in a hunting magazine that the diamter of the bullet not is so important if you hit the vital parts in game.. So is it only the leaved ginetic energy in the vitals that is important for the effect on game like moose?
If you shoot a moose in the shoulders at 50 yards with a .308 Win "low kinetic energy" and then make the same shoot with a .30-378 wby high velocity(3500 fps with a 180 grainer) and ginetic energy. Will the effect be much better with the .30-378? Is there a "shock effect"?
I have shoot at 20 l cans full with water with a 6,5 x 55 swedish mauser and it was not any explosion. But when i shoot it with my .460 wby (500 grainer at 2600 fps) then it was a very big splash. The hole can explod. The pressure "splash effect" has to do shock in the vitals as lungs.
Last year I shoot a moose right in the heart with the 6,5 x 55 swedish mauser and the heart explod. That is the best shoot placment to turn of the blood pressure in game. BUT the moose still run for 100 yards. And my buddy say that if you make the same heart shoot with your .460 The moose will die on the spot.

What do you guys think of shock and splash effect?

Thanks!

My own experiences have been that my quickest kills were with rapid expanding bullets at very high velocity.My last four elk and two moose were killed with 180gr ballistic tips with a muzzle velocity of 3375fps and five of the six animals went down on the spot or took a step or two.The sixth,a 1200lb bull moose walked about ten steps before dropping.

I have found the light highly strung animals like deer and antelope respond to velocity, but the big ungulates are better shot with big bores at reasonalbe velocity...The big bores also leave a better blood trail...

I had enough bullet failures in the pre-premium days to learn my lesson....give me a big gun and a heavy bullet for about anything, I might not get those instant kills that get people all excited but I get a postive kill everytime and a good blood trail to follow...

The 22 centerfires will give you a very high percentage of instant kills but if the animal runs you may have just lost him. I have seen this happen many times...shot him with a 180 gr. 30-06 and follow him until his tank goes empty...

Velocity is also very meat destructive...
