" Faster bullets can actually reduce penetration due to rapid premature expansion, as well as causing significant meat damage.
The 2 calibers were 7x57 Vs 7mm Rem Mag and 308 Win Vs the 300 Win Mag. Loaded to factory specs, using the same bullets. 139 & 180 gr. respectively.
.... as the standard calibers penetrated 25-30% deeper than the magnums." Brayhaven From P 5
I am still being polite.
I wouldn't be surprised if the new copper bullets TSX etc, did penetrate as well at higher velocities. They penetrate much better in the classic calibers,
... I now use those TTSX (type) bullets in about everything, including my 7x57R drillings with great success. Calibers that I once considered poor for deer, like the 243, are much more acceptable with bullets that stay together and finish the job.
It 'seems' to me you know Premiums penetrate 'farther' with higher velocity, no ?
