Another what if question.........

Im Just gonna answer your question and say ... 300 WSM FOR SURE ! make sure it has a tight enough twist to run 180+ grain bullets. Ive shot this calibur for 10 years now and have had it in 3 diffrent rifles. Ive always had a fassination with this cartridge but now ive bin reading on http://www.accurateshooter.com/ about it and the 7WSM. These have turned out to be amazing cartridges. The 300WSM has turned out to be one of the most accurate modern " MAGNUM " cartiges designed and set a 10 shot 1000 yard heavy gun class world record in 2010, The 7WSM is right behind it with much higher B.C bullets.

I would hunt anything in North America with this cartridge ... However, If you get up close and personal with a G Bear and it gets real hairy ... Be prepared to be eaten by a G Bear that has a magazine full of 30 cal bullets in it :)

Im not sure exsactly how far your gonna go ... Factory or custom, but these articals are more just a testiment of the cartridges capabilities.

Just for the sake of argument, do you believe that a given cartridge kills the same at every distance? 100 yards, 500 yards = same thing?

Is that not a function of bullet design and construction? Higher impact velocities result in a more violent and rapid bullet expansion, which results in a wider though shallower wound, while a lower velocity bullet impact deforms the bullet less, resulting in a deeper, though narrower wound. The more velocity it takes to deform the bullet, the deeper and narrower the penetration will be. Wound volume though remains the same. Your question would not come up if we used only solids, as their effectiveness is a result of penetration and frontal area alone, and impact velocities of 2000 fps are sufficient to ensure deep penetration with a non-expanding bullet. Expanding bullets muddy the water to the extent that their frontal area changes with impact velocity, and the degree of expansion has an apparent effect on the shape of the wound, if not its volume. But if we compare a 180 gr .30 caliber bullet that expands to .60 caliber, to a 900 gr .600 solid, the 18" of penetration we observe from the .308/180 doesn't make it the killer the the big bore is, on game that requires 30" of penetration to kill. Similar comparisons might be made between a .243 and a .458, and you can't get close enough to a buffalo for a .243 bullet that expands to .45 caliber to be as effective.

So a 30-30 is the equivalent of a .300 Win Mag??

At say 150 yards do you think the animal will notice a difference? The 30-30 wont bounce off like the hide is made of rubber because the same .308 diameter bullet isnt going at 3000 fps. Dead is dead just depends on how much money you want to spend getting there

If we were to compare the effects of both cartridges loaded with solids of the same shape, hitting medium sized game the there would be little difference in the animal's reaction to being hit with either. This suggests that any difference in observed killing power between those two cartridges is a function of bullet design and construction, and not velocity. The bottom line is that you can only do so much with a .30 caliber bullet no matter how you dress it up. If a bullet is made heavy for caliber, with a long soft core or hollow cavity in the case of a monometal, so that it expands to a larger diameter than a standard weight bullet, while the additional weight produces sufficient momentum to ensure deep penetration, you will see a greater effect on the target despite a lower impact velocity, so velocity is not the primary ingredient in the killing power recipe, frontal area and momentum are. What velocity does do is make hitting at long range easier.
 
what most people DON'T REALISE is that any of the so-called 30 caliber magnums are just 308S ON SPEED- that's all- and the more the speed, the MORE EXPENSIVE it is to operate- starting off with the 308 win, the 06 is all of 200 feet per second faster but EXTENDS THE RANGE by only NINE yards- and takes another 10 grains of powder to do it- move up to the 300s( any of them) and you get a substantial increase in powder burned and all of maybe another 50 feet- the 300 wm pbr is 325- so get an 06 or a 308 and BE DONE WITH IT- you also LOSE TWO ROUNDS when you join the belted magnum club, typically- so you ask yourself, do i want 5 shots or only 3?

There is nothing in all of North America that would walk off a 130gr TTSX. Unless it didn't expand. :)

IIRC according to Barnes that just needs to be around 2000 feet per second. :D

Found via google:

"We test our bullets into water for expansion here at the Barnes facility. However we have found that quite often they will expand at lower impact velocities in the field on real tissue and bone. With this said, the .308 cal 130gr TSX requires 1800fps in our test and the .308 cal 130gr TTSX requires a minimum of 2000fps. I hope this information helps you to make an informed decision." you to make an informed decision."

If I was going to inflict a .300 magnum upon myself, it would be of the H&H, Winchester, Weatherby persuasion, and I would not hesitate to use any of them on big bears with a decent bullet. Here's the thing though, the only advantage a .300 has over a .30/06 is trajectory, its still the same .30 caliber bullet that lands on target, so if I need more than a .30/06, I'd be looking at the larger frontal area and heavier bullet of a 9.3 or a .375, and neither would be as difficult to shoot as a .300 in a flyweight rifle.

ha, an excellent choice of words, Boomer! I love it! Coming from a happy 308 man! :D

What the hell kind of argument is this. Holy man.
 
Lmao! this thread is quite comical!

There is some great info in here though, but most of this thread is hilarious! Useless, but hilarious! I hope Waterfowler is enjoying the silly responses as much as I am lol

You assume the same bullets when making this statement. But the advantage of the .300 Magnums to me is that they will push a heavier bullet to similar speed as the .30/06 or .308 Win does with a lighter bullet. I am not really interested in ultra high velocity - a 200gr Partition at 2900fps or a 220gr Partition at 2800fps is just about perfect, imo.

Edit - if one cares to throw around numbers, my 220gr load has the same momentum at 275 yards as a .30/06 with 180's at 25 yards. The Optimal Game Weight rating is the same at 200 yards as the .30/06 at 25 yards. For Taylor KO the 220gr load is higher at 200 yards than the .30/06 180gr at 25 yards.

The performance on game is stellar.

Which is my excuse for choosing the .375 Ultra over the .375 H&H, it will drive 350 and 380 gr bullets 100 fps faster than its slimmer brother, resulting in greater upset over normal ranges. My .30/06 will push a 240 Woodleigh at 2350 give or take, and the .300 would better that by a considerable margin, although Woodleigh recommends impact velocities of 2400.
