Went to ableammo.com and checked a few different models in .270 vs .308 and there was no difference in listed weight. Before you buy your next rifle, see how they compare. How we will compare penetration of these two rounds is to look at the sectional densities (SD) of the bullets as it allows us to look at the two cartridges rather than the differences between bullet styles. Sorry for the week delay on this one. For more experienced hunters, most hunting cartridges, including the .270 and .308, the recoil is going to be manageable. Though we will look at each of these categories separate from the other, in reality, all of them influence and play off of one another. So, let’s take a look at the sectional densities of the ten rounds we have been using for comparison and see if any trends emerge (Graph 9). Legal Disclaimer. In the end, the best cartridge all depends on the type of situation they will be used. What this number tells you is how well the bullet resists wind drag and wind drift throughout its flight path and gives you an idea of how well a bullet will be able to cut through air and wind resistance. I got my 11 year old the CVA 308 and he loves it. But to make the task of choosing one which suits your hunting best much easier, let’s walk through their most outstanding features.

The “felt recoil” involves a lot more factors than just the type of cartridge used. What you should take away from this section is what the BC means, as stripped down as we made it, and the understanding that between these two cartridges, the BC can vary pretty wildly with high and low performing rounds for each. Both have a bit of a kick, but for hunters and marksman with a little experience it’s nothing you haven’t felt before, and it shouldn’t impact your shot in the field. The bullet energy is the highest of the selected .308 rounds with 1,300ft.lbs of energy at the 500-yard mark which is enough for even larger game at that range. This is a common question many hunters have, especially when considering a hunting rifle for younger hunters. Even with these various variables, we have kept everything as constant as possible, and the trends that we see should hold up. For shots taken at extended ranges, a higher BC often means fewer adjustments will have to be made to get the bullet on target. The theories and physics behind the ballistic coefficient can get a little out there, so we are going to simplify it in this article. For larger game such as deer and elk, both cartridges have enough stopping power at short range to drop animals cleanly. What should be taken away here is that both of these cartridges have rounds that are going to range in sectional density. Both are fantastic cartridges that have been tried and tested in the field for decades. While the differences are not too dramatic between these two cartridges, we still see the trend of the .270 Win having a flatter trajectory than the .308 Win. A debate that comes up often is which one is better when comparing the 270 vs 308. With the larger data set of factory loads for each of these cartridges, we can be more confident that the conclusions drawn represent the full set of round options for each cartridge. Based on their hunting use, we don’t see any real difference in price between the two. We will also take a look at other categories such as recoil, accuracy, and availability of the ammunition.
