130gr in a 30-06

[marketello]

I understand the the BC of a 130gr in a .277 bullet is better than the 130gr in .308, but how close would they compare in the field.

If a handloader loaded a 30-06, 130gr with the pressures close to that the .270 is loaded to, how close would the 30-06 mimick the .270?

Would the trajectory be so close that one couldn't tell that they weren't shooting a .270?

Greenhorn, a multiplex level question. The 277 bullet would fly flatter with the same velocity, BUT the 06 might squeeze out a higher velocity since the 130 is light for the caliber. Higher velocity could help flatten out the trajectory, BUT now you are driving a light bullet MUCH faster than it was designed for by the maker. Maybe, the 139 30 cal Barnes TSX might be OK at higher velocities (talk to Barnes. I understand that some folks are driving the 130 TSX fast in 308s). Usually, heavier weight bullets will be flatter at long range in 30 cal. Look at the 165 gr bullets and heavier for both energy & trajectory.
