I've made mention of it previously after following many of his articles in various publications, in the mid 70s I had the good fortune of meeting with him, on two occasions. I consider these meetings to be the high points in my years of shooting. The 1st meeting was a very informative and enjoyable day spent with him at his home in Salmon Idaho. And again, this picture, presently serving as my avatar, was taken as I was preparing to depart.
My 2nd meeting with him took place at a dinner in his honour after a gun show in Kalispell Montana.
Even prior to that time and at a point at when I was first really getting involved in handgun shooting, I sent him at least two letters, making inquiries to aspects of shooting and hunting I was unsure on. Replies were timely and to the point.
I admit to being a fan, that's a matter of record and truthfully, I was quite suprised by the SMS insinuations. In my meetings with him, in correspondence with him, in his articles published in various magazines and in his books, I have never seen any indication that would even remotely confirm that. What I have found to be closer to the truth is his writings, opinions and conclusions are the result of what he found to work in the field.
Yes, his experiences and opinions differ sometimes considerably from those of some of his other 'colleagues' of the day, Jack O'Connor for example. While admittedly I am primarily a fan of Elmer, I have nothing against Jack and contrary to Elmer, I do have a 30-06 and a pair of 270s.
Technology, especially that of bullets, has evolved considerably since Elmers hay-day but part of his rationale for bigger may be explained by this quote.
SMS, I don't think so.
