o.k. here goes. a couple of days ago a friend and i were talking about deer rifles. i have a .300 win. mag and he has the new .300 WSM. i mentioned that they were about the same as far as ballistics go and that i could see no advantage to buying a new rifle if it wont shoot any flatter or hit any harder than what i already own. well this other fellow who was passing by started telling me how the short mag. was much better than the old win. mag. so i told him he was full of crap. well he went into his office and came back out a few minutes later with a paper he had printed off the internet comparing several different .30 caliber rounds.it said that the .300 WSM shot only 10 fps faster than my old .300 win. mag. but in the energy column it listed the short mag. at about 800 ft. lbs. over the win. mag. at 300 yards. QUESTION, if 2 identical bullets leave the barrel at the same speed how does one carry more energy at 300 yards than the other. my answer is that it cant so now i am looking for other opinions or some hard facts. all opinions and facts welcome.

800foot pounds sounds like a misprint(not sure tho)the only way two bullets of the same weight at the same ft second would be if one of them were a boattail as the boattail design will retain more energy downrange,also the new groove bullet can be launched much faster the only way to be sure would be to chronograph both rifles(you may find there isnt even that much differance between the two)

I haven't looked them up on the ballistics chart, but you are right - if the two bullets are identical (same ballistic coefficient) and they leave the muzzle at the same velocity, then downrange the velocity would be the same and the energy from each bullet would be the same.

There is not that much difference between any of the new short mags. The energy level is much closer and you are right. Yet there is much misinformation out there it is mainly marketing. You have to sell new products in any retail market. New calibers means new customers. How many people with a 300 mag wants to buy another 300 mag, yet the 300 WSM is a "totally" different round thus you have gained customers  |

Energy doesn't kill. Disrupt the brain or sever the spinal cord. Otherwise, blood loss is the big killer. The faster the drop in pressure the better. Keep in mind, a hole in both sides lets the critter leak more, and makes easier tracking. Keep faith in what you have, choose the bullet construction for your target.

It's easy to calculate,,, take the velocity in feet per second (muzzle, or down range) and square it. Take the answer from that and divide by 7000, take that answer and divide by 64.32. Then take that answer and multiply by the grain weight of the bullet. This answer is energy in foot pounds. ....  Be sure to carry this around to impress the elk you shoot,,,,,  Good Shooting, MaBell |

 hey h9850 use mabell's formula using velocity of each at 300 yards and politely tell friend that after some investigation into the matter that u know for sure he is full of caca. there is about 500 ft.lbs. of energy difference between a 300 rem ultra mag. and the old, almost obsolete 300 win mag. ( jokin' of course)
