30-06 is more powerful
.270
270
Really depends on the load, but the .270 is typically the more powerful of the two.
The 270 is more powerful. The .270 has a slightly larger projectile in diameter (.277 vs. .224) and a significantly heavier bullet (between 90 and 150 grains, vs. 45 - 80 grains for .223/5.56 loads). Additionally, the .270 utilises a much larger casing - the .30-06 casing, necked down to accommodate the smaller projectile of the .270 cartridge.
Yes 3006, 270 is a long action 308, 243 is a short action.
3006 weeks = 3006 x 7 days = 21,042 days
Need much more information.
I'm not quite sure about the 3006, but I know that the longest recorded kill shot with a .308 was at about one and a half miles, possibly more.
A .270 might fit the bill.
You need more information for an answer. If you are trying to write 270 as a percent: 270/1 = 27000%
General rule of thumb is that the best caliber is the one which best suits you. Of the two, .270 would be the more powerful round. Both are substantial for hunting something like deer, although the .243 is probably better suited for the experienced hunter, whereas the .270 would be a little more forgiving to the novice hunter. The .270 is a necked down .30-06, and the .243 is a necked down .308.
270 is less than 1500, because 1500-270 > 0.
