what are you shooting at? or hunting?
any of the ones you listed will go 300 yds fairly accurately with the right gun/shooter.........however I understand that the .270 has a flatter trajectory.
I'm not an expert at rifle calibers by any means, but I think it is going to come down to "what your intended pupose is."

270, 308, or 3006 are all good at 300 + yards.

My choice of the 3 for accuracy would be the 308. Whoever told you the 308 was not a good choice should be bitch slapped.

The most common military and police sniper rifles over the last 50 years have been chambered in ..... you guess it ..... 308.

If you are hunting big game at distance, you might want to consider one of the 30 caliber magnums for their long range terminal ballistics. But if metal is your prey, the 308 is hard to beat.

Deer hunting mostly,later maybe something a little bigger.Dont wanna buy another one later.

What do you hunt?

white tail

Numerous Deer (Mulies) and several Elk were harvested since 1961 with my .308 with 1 shot kills. Range has varied from 50 feet to the vicinity of 300 yds. I have never used a range finder. I sight dead on at 200yds. and just aim a bit high for the longer ones.

I own a .270 but it has only fired at paper. It is the backup to my Winchester model 88 .308.

Good luck.

theres a reason that .308 is the most prefered sniper rifle^^^ hhahaha its probably gona have the flatest trajectory at 300 yards

Note: These ballistics reflected a test barrel length of 24" except those for 30 Carbine and 44 Remington Magnum which are 20" barrels.
Specifications are nominal. Ballistics figures established in test barrels. Individual rifles may vary from test barrel results.
“zero” indicates yardage at which rifle was sighted in.

I like the 270 for varmint size hunting and the 308 for deer size.

Well that didn't copy very well - got the info from Remington ballistics web site
