I've had a love/hate relationship with Craig - or at least his writing - for most of my literate life. Meaning I hate that I love reading his work. I indeed have kept subscriptions with magazines only because of his content, and I've bought a number of his books over the years. More often than not, I'll enjoy his writings, but also more often than not, I'll find some expressed opinion here or there within a work which rankles me. But I suppose that attribute has played a part in his success over all of these years.
Naturally, the frustration comes when we read a statement like that from a guy like Craig who should readily recognize that a 130grn pill out of a 270win has the same SD and approximate energy as a 168grn from a 30-06, only ~ 5-7" less drop at 500yrds, and only about 2/3 the TKO factor at 500yrds. If a 270win can do it, a .30-06 can and will do it, and do it harder... You'd also expect he recognizes both will have the same rifle length and weight for packing as well, and only a fractionally appreciable difference in recoil... One thing to say he prefers the 270 over the '06, but to recommend one as sufficient and one as deficient isn't logical.
I haven't killed sheep with an '06, but I've killed elk between 300 and 500yrds with them, and whitetail & mule deer past 700yrds. If I had to reach farther, I know I'd want a 168-180grn pill, regardless of the speed and trajectory difference, instead of a 130grn pill.
