SubZero, all BS aside, with what calibers you have there is no advantage to owing a 308, other than that ammo is much cheaper to buy. both are quite capable of doing most any hunting you plan on doing as long as you pay attention to shot placement. both of the those calibers are fine choices to own and hunt with. buy a 308 if you want one, but there really won't be any advantage over the two you already own.

I also have the 300wsm. I feel it edges out the 308 in everything other than ammo cost. Stick with that and the 270. Heck, you could sell the 270 and do everything it did with your 300wsm (that is exactly what I did actually). I liked my 270, but didn't use it much with the 300.,

Here is actual data, now the .270 is using a 160gr while the .308 is using a 168gr match as there are no match bullets for .270. MV in the .270 is 2650, .308 is 2700. I am rounding both down. The .270 by 30fps and the .308 by 50fps because no one uses max loads often.

Bullet drop in inches w/ 100 yard zero:
.270 at 250 yards, -9.6, 350 -24.1, 450 -48.3, 550 -83.3, 650 -131.6
.308 at 250 yards, - 8.5, 350 -22.9, 450 -45.9, 550 -79.1, 650 -124.8

Not sure what physics you were talking about that pertain to accuracy. They both shoot pretty even. I'm not seeing a 300 yard advantage at all. All loading data is from the Hodgdon site, everything calculated on a JBM calculator.

With 150gr ballistic tips the .308 has the advantage again in MV by 100fps+-
.270 at 250 -7.6, 350 -20.6
.308 at 250 -7.1, 350 -19.3
The long bullet of the .270 may perform better on game at distance, but not on paper.
I just bought a .308 over a 30-06 or 270 because I felt it was enough and I was sick of the weird hard to find calibers I was shooting,but my buddy uses a 270.We both like 150 gr for each of our guns best,I noticed that his shot 30fps faster but I was shocked to see that after 100 yards the 308 is always faster and flatter than the 270,I just wouldn't have guessed that,figured the 270 would be more aerodynamic but maybe that bigger 308 had more of a wing effect,i'm not sure,I can't wrap my head around it all

It really depends on the bullet. The Kid keeps spewing 3000fps, but still gives no info as to where it comes from. When you deal with fan boys of a certain cartridge, they usually are full of excrement from a horned animal. I don't own a .270. Never will as it is redundant to many other calibers I shoot.
Even the 7mm Rem Mag would be lacking to him I'm sure. Don't sweat it, just do the best w/ the equipment you have. I doubt kid will ever shoot past 100 yards, but is a classic fan boy. Probably 16 or 17 years old.

actually he moonlights as an engineer for NASA when he's not making those video's of himself shooting his 30-30 at 600 yards!

Never saw them. He is FOS. Nasa engineer or not, I guess not. My Dad worked on the design for the LEM, F14, FB111, A6, A6E. It did not make him perfect and unquestionable. Without facts it is here say. He has no facts. I understand where you were going, and agree. But he is a moron that will end up in the FTF hall of shame. He needs to be called out. Here I is!!!
The info of 3000fps for a newbe reloader can lead to catastrophic failure, completely irresponsible.

I was comparing winchester of the same offering on the winchester ballistics calculator like 308 superX vs 270 superX both 150 gr,308 muzzle velocity was 2,820 and 270 was 2,850,but after 100 yards that 270 dropped in velocity more and was slower after that than the 308.I seen some Hornady superformance 308 150@3,000 fps stuff at the store but i'm not tempted,I want my hunting ammo to be the same weight and velocity as my cheap rem core lokt ammo I sighted my gun in with,not that the rem is not good,I just want something special like an HP or ballistic tip-not special like so hot i'm coming out of the woods with a miss and a bleeding forehead.

The only one that sounds like a moron is you, with a little research hornady superformance which is factory ammo claims 3200 fps. Oh my god hornady is headed for catastrophic failure. Give me a break, I even provided a link for you to prove it, the only fan boy is you. http://m.hornady.com/store/270-Win-130-gr-SST-Superformance/

Hornady also uses very fast burning powder to push their bullets to edge of the envelope. not something a novice reloader needs to be doing, pushing the envelope to the edge. yes i have shot many a box of factory ammo including Hornady and i use a lot of Hornady reloading components. one thing i learned about reloading, follow the reloading data in the book. there is a reason why, safety. Hornady has engineers and people who do nothing but reload and work up ammo data everyday, day in and day out. careful about throwing out calling people a moron, because you are very close to being one here!

Not the same bullet but heres a formula for you 130 grain barnes triple shock 52.2 grains of hybrid 100v starting load velocity is 2994, max load 55.5 grains velocity 3144. I was calling him a moron for not admiring it could even be done, I would not advocate a new reloader try something dangerous.
