I believe it was an article written by Bob Jourdan years ago, that suggested to choose a well constructed bullet, suitable for the non-dangerous big game (deer and such) intended, of at least .25 sectional density, and pushed as fast as the cartridge will allow, with the recoil you can tolerate. The 270 with a 130 grain bullet has an sd of .242 and hits all the other parameters. But i went with a .280 because the 140 grainer has an sd of .248 a little closer to .25, with a little bit more diameter and weight. I can't fathom how a partition in either would fail if i did my part.
the 28 Nosler seems too much of a good thing. A hunting buddy has a 7mm Weatherby and swears by it. It is his lightning stick.
Seems to me we will have better success with training with what we now have and know.
