some countries have a "thing" about civilian use of military calibres, so 30-06 maybe a more sensible choice
its a necked down .30-06
Still a big cartridge though.
No Alsone the .270 winchester is derived from a necked down .30-06 not the earlier, very short run .30-03 which was considered underpowered, so was altered and became the .30-06, the .25-06 .270, are simply necked down versions of the .30-06, parent case.
Not according to the Complete .270 Reloading manual (2004) or the Wiki:
While it is true that a .270 Winchester case can be formed from a 30-06 Springfield case, the case length of a 30-06 is 63.3 millimetres (2.494 in) while the case length of a .270 is 64.5 millimetres (2.540 in), the same as a .30-03 Springfield. It is recommended that .270 Winchester brass be formed from .35 Whelen or .280 Remington cases.
Whilst it's true the 30-03 was superceded by the 30-06 within a couple of years of it's launch, the .270 case is said to be actually based on the .30-03 case not the .30-06.
I wasn't trying to be pedantic btw, just correct the thread for posterity.
