.270 win vs. .308 win

As deer season is coming our way, I have a .270 and a .308 that would suit the job just as equally but the deal breaker is gonna be hogs. So all your great input would be much appreciated.

Re: .270 win vs. .308 win

I'd take the .308, but that is just personal preference. Either one will do the job on both without a problem.

How's the .308 supply in your neck of the woods?

The last time I checked, the ammo cage at my local Walmart was 1/4 full of .270, so I'd go with that.

If you analize all of the facts the 270 is the better round, but I like a 308 rifle better. With lighter bullets the 270 shoots flatter and will generate less recoil. With heavier 150 gr bullets it will perform on game about like a 165 gr 30-06. In otherwords it will do just fine on game up to elk or moose, it won't have a problem with hogs. With either round bullet choice is the key.

I just like my 308 rifles better. They doesn't shoot quite as flat, not quite as powerful as the 270 or 30-06, but close enough that there isn't an animal on the planet I'd hunt with one of the 3 and not the other.

I've just come to appreciate the lighter more compact rifles that can be designed around the short action rounds. Saving 2-3 lbs on my rifle weight is more important to me than 100 fps.

Both make excellent deer and pig medicine, I doubt the game is going to be able to tell the difference. I think the choice really comes down to which one you want to carry

Out to 300 yards, which should be the extreme limit for 99% of people, the difference between bullet construction will be greater than any other criteria.
If I'm not shooting, I'm reloading.

Both work very very well so it wont matter much. But if you really want to compare. The .270 starts with more muzzle energy, fires bullets at faster velocities (flatter trajectory+ less ETA to target) and the 150 grain bullets in .270 have better sectional densities than 180 grain bullets in .308

.270 also seems to be much more available during panic ammo buying, which may be something to consider. .308 is more popular, but this can be a bad thing now-a-days. If a lot of people have .308's it means a lot of people are going to need ammo for their .308's.

The .270 is a underrated cartridge capable of very long range shots, and proven it's capable of harvesting any type of game, with the right bullet.

A 130 grain in .270 should have no problem taking large hogs. A 150 grain could probably harvest 2 with one shot, if you line them up right.

I'd go with the rifle rather than the caliber.
Which comes up and gets on target better for you?
A target rifle, you have time to settle down and get into, a hunting rifle, not so much.

Both calibers will work well. Flip a coin.

Both excellent cartridges, that being said I have 3 .308's.

.308 gets my vote.

308 is more versatile no doubt about that. But the 270 shoots flatter. So not wanting to ruin any more bacon than need be. I'd go with the 270 for distance head shots on those medium size porkers myself._

I have both and use them inter-changeably on hogs. I use Barnes TSX 140gr bullets in my .270 and 168gr Barnes TSX in my .308.

308 here just because. No real reason other than the 308 is---well it's a 308.
Both are good. 270 as stated will have a flatter trajectory--At 300 yards this is not a issue nor is the extra 100 fps.

Which one do you shoot best? Either one will handle deer or pig just fine.

Both are just fine. Since I own a 270 win, that is what I would choose.

308 vs 270

Here in South Africa most of the guys would go for the 308 most consider the 270 to be too fast and too light. That being said it depends on what distance you will be hunting most of your game. Anything under 200 metres go for the 308.

Here in the U.S., we do not have guns that are calibrated for meters...ours only shoot in yards.

Both are very comparable in terms of power as you've stated. The .270 starts out marginally better but that gap widens as range increases.

Just to put some data on the table for people to see the differences, here's an example. Lets compare a 180 grain in .308 to a 150 grain in .277 I chose these weights as I thought the bullets were most comparable. They have similar Sectional Densities (with the 150 grain having a slight advantage) and ballistic coefficients (the 150 grain in .277 having a slight advantage again-of course this can vary with bullet choice)

They both leave the muzzle with similar energy, with factory ammo. The .308 leaving at just over 2600fps and the .270win @ 2850fps.

@300 yards
.308 2124fps
27.37'' drop
.39 seconds flight time
6.76 inches of wind drift with a 10mph 90 degree crosswind.
1803 ft/lbs energy left

.277 2358fps
22.65'' drop
.35 seconds flight time
5.83'' wind drift w/ 10mph 90 degree crosswind.
1852 ft/lbs energy

so as we can see the cartridges are very close to each other. The .270 having a slight edge @ 300 yards due to it's marginally shorter flight time, ~5'' less drop, ~1'' less wind drift, and 50ft/lbs more energy. Along with the better sectional density of the 150 grain, all these things adding up makes the .270 the "better" cartridge.

The difference is small enough that it doesn't really matter though. Both will be very effective for their chosen job. I'd pick the .270 simply because it seems to be more available during panic times. The .308 is such a common and popular cartridge that many people are shooting it, and therefore buying it. Normally it wouldn't matter but after our most recent ammo shortage, it's easy to see that the .308 may get hard to purchase again. And with it being such a popular cartridge demand will be higher. Supply and Demand: if more people need it and less have it, prices go up. From my limited second hand experience, it seems that .270 ammo is staying on the shelves, even during panic times. The .308 is not.

.223 will drop hogs all day long, so I'd imagine that your two chosen calibers would be more than enough.

With that being said, I'd go .308

I prefer the recoil of the 30's over the recoil of the 270 or 7mm mag. I can shoot either all day but ro me the 30's recoil feels more like a push where the 270 n more so the 7mm feels like a slapping push. Jmo

I don't own a .308, so that means the .270 wins quite easily.
