Re: Long Range with old cartridges
Both cartridges would be great at the range you indicate. Palma shooters are shooting 150-155 grain bullets from their 308's as a rule.
Check out any number of ballistic calculators using the BC's and velocities and go with the one you feel best with. 130,140,150 grain bullets are all good for the 270. I would suggest you practice with the bullet you will be using for hunting. Practice a lot at the range and under the same circumstances,ie,prone or resting over a rock so you can be sure of your shots.
