Big and slow VS Small and fast = Knockdown Power

I can tell you from my first hand experience that physically I am big, heavy and slow and I cannot get through the branches and leaves near as easily as the small, light and speedy guys!! That lays this argument to rest!! ;)

Given those criteria Spank you win hands down...........our Pygmy tracker went through the Congo bush like it wasn't there I however struggled with nearly every step........branches, vines, bushes, some plant with leaves the size of bath towels.........They had to machete me a hallway through this stuff, but whenever our Pygmy decided he would just silently disappear.........small and light definitely goes through the bush much better. You should have watched all our trackers disappear, for hours after we walked into the middle of a small herd of them nasty little forest elephants.......what had been a cheery bunch with 3 black faces and 3 white faces became only 3 white faces in a New York minute..........

I guess it wouldn't plot a straight line on a graph then, cuz I'll bet those slow and heavy elephants could make their way through the thick brush faster than the remaining 3 white faces!
 
It more important to me to choose a caliber that's rarely available
nothing worse then not being able to get ammo wen you need it happens way too often to me on Haida Gwaii
Now I use a T/C pro Hunter as a back up rifle and caliber choice is based on what the Co-Op has in stock love that rifle all my barrels are 15" except for the 12 gauge turkey barrel
Short barrels is the way to go on the BC coast

I saw a quote somewhere, maybe here on CGN, that said: Velocity drops off, Mass doesnt.

The reason for using a heavier bullet on big animals eg; moose is they have a hollow or larger hair and small calibers tend to spin out in the hair - no entry wounds

On windy days I hunt with Slow and heavy and Keep shoots under 150 yards
On open land and good weather speed rules

I'm curious why you shoot slow and heavy on windy days? You're not alone, a lot of folks talk about bucking the wind with big slow bullets, but any old ballistic chart will clearly show that speed is the only thing that prevents excessive drift. A .270 or 25-06 in a 10mph crosswind will drift 1.5 inches at your 150 yards. A 45-70 will drift 6 inches.

Am I missing something? Why is slow and heavy better for wind?

Being on the Haida Gwaii we see sum of the Worse Wind on the BC coast
Late fall and winter is wen we hunt it not uncommon to see 200mile winds
The stronger the win the closer you have to get thers no Long range hunting in a strong wind
At Close range slow and heavy will out perform the fastest magnum
I have bin hearing some good things about some of the new bullets being able to perform at both short and long distance but haven't seen it for my salf
I have nothing against the flat shooting magnums and understand the need for them but thers a need for the fat slow moving girls to haha

I am completely confident in one of 3 things: That you have never hunted in 200mph winds, that "200" is a typo, or that you have had one too many wobbly pops. Or perhaps all 3.

Regardless, even in very high winds, a faster bullet still drifts less than fat and slow. For giggles, in 200mph winds, a .270 will drift 31 inches at 150 yards. The 45-70 will drift 130 inches.

So where does this common belief come from? There must be some reason folks believe this...

I don't hunt in 200mph winds but I do hunt in sum big winds last deer I got was bedded down hiding from the wind gust up to 60km and raining like a basters
Most moose I have gotten wear bedded down as well I just can't see how fast flat shooting magnum will open up at 25 yards don't get me wrong I have a 6.5CM I realy like but I realy like my 44mag both are grait deer rounds and in a pinch I would use both on moose so I'm on the fence on this debate
Ther is no question the flat shooting magnums and the fat girls both work and it gets more intersting as we dig into it more

Well, a moose in the freezer is a moose on the freezer, so if it works for you, have at 'er.

I've got nothing against the big bores... Love 'em in fact. But choosing a big bore specifically to compensate for wind is just plain wrong. Worse than wrong - it's exactly backwards.

Your deer bedded down in 60kph winds at 150 yards is a perfect example of how dangerous that myth can be. If the wind was sustained at 60, your 6.5 CM would drift less than 5 inches, and deliver just shy of 2000 foot pounds of energy. Your 44 mag will drift a whopping 3 FEET at that distance and deliver about 700 foot pounds of energy. That's a wounded deer with his ass half blowed off. Even at 75 yards you're looking at 9 inches of drift, which could increase the likelihood of a gut shot animal.

I guess my point is, forget the campfire stories. Get some balistic tables for your rifles and study them so you can make the best decision when you open your gun safe on opening morning. Big and slow is great, but grabbing your 44mag or 45-70 BECAUSE it's windy is an injured animal waiting to happen.
