A 300 win mag vs 338 lapua might be more comparable. Why bother with the 338 if you budget, skills and location will never put you in a situation where you can shoot farther than the capabilities of a 308. I have a 308 Savage. I have a 300 yard range available locally and possibly a 1000 yard range about 2 hrs away. The following ammunition cartridge ballistics information and chart can be used to approximately compare.308 Winchester vs.338 Lapua Magnum ammo rounds. Please note, the following information reflects the estimated average ballistics for each caliber and does not pertain to a particular manufacturer, bullet weight, o.
Rifle Recoil Table

For every action there is an equal and opposite reaction; that is one of the physical laws of our universe. This means that the momentum of a rifle's reaction will exactly equal the momentum of the bullet and powder gasses ejected from the barrel. In the shooting sports we call that reaction recoil or 'kick.' It can be measured or computed empirically and has been for this recoil table.

Do not forget that rifle weight is a crucial factor in the recoil equation, inversely proportional to recoil. Increase the gun weight by, say, 25% and the recoil goes down by 25%. In the real world, firearms chambered for less powerful cartridges are typically built lighter than firearms chambered for more powerful cartridges. Violate this principle by, for example, chambering a lightweight, short action rifle for a powerful Magnum cartridge like the .300 WSM and the result will be a dramatic increase in kick. Just because it can be done does not mean it makes sense, despite what you might read in advertising copy. Choose a rifle weight appropriate for the loads you intend to shoot.
However, perceived recoil, what the shooter feels, is a highly subjective matter. In addition to gun weight, it is influenced by many factors. One of the most important of these is the fit and shape of the rifle stock. A good recoil pad can help soften the blow to the shooter's shoulder. Gas-operated semi-automatic actions reduce apparent recoil by spreading it over a longer period of time. These sorts of things cannot be accounted for in a recoil table. Also, please understand that there are dozens of loads for any given bullet weight in any cartridge that will produce the same velocity, but a different amount of recoil. So the figures in any recoil table should be taken as approximate. Never-the-less, the table below should give a reasonably accurate comparison of the recoil of most popular rifle cartridges.
It is worth remembering that the majority of authorities agree that recoil of over twenty foot pounds will cause most shooters to develop a serous flinch, which is ruinous to bullet placement (the prime component of killing power). Fifteen foot pounds is probably about the maximum recoil energy most shooters feel reasonably comfortable with, particularly at the shooting range, where most serious marksmanship practice occurs.

While recoil energy determines how hard the blow to the shoulder feels, recoil velocity determines how abrupt the blow to the shoulder feels. My subjective impression is that, with a well designed stock, recoil velocity above about 10 fps begins to feel like a sharp rap on the shoulder rather than an abrupt push.
In 1909, the British Textbook of Small Arms stated that 15 ft. lbs. of free recoil energy was the maximum allowable for a military service rifle. (The standard British .303 Lee-Enfield infantry rifle was below that figure, as are most service rifles to this day. This should tell you something.) The 1929 edition of the same textbook stated, in addition, that recoil velocity should not exceed 15 fps; above that velocity a gun-headache was very likely to occur. These figures remain practical maximums for the modern hunter.
Above this level recoil becomes increasingly intrusive. In addition, the effects of recoil are cumulative. The longer you shoot, and the harder the rifle kicks, the more likely you are to flinch. These are good things to remember when comparing rifle cartridges.
In the table below rifle weight is given in pounds, free recoil energy is given in foot pounds, and free recoil velocity is given in feet-per-second. All recoil values have been rounded off to one decimal place.

The recoil energy and recoil velocity figures are taken from various sources including the recoil nomograph in the Handloader's Digest 8th Edition, various online recoil calculators, the Remington Shoot! program or calculated from the formula given in the Lyman Reloading Handbook, 43rd Edition.
