From an article published in the 8th Edition of Handloaders Digest, "Handloading for the 270" by Jack O'Connor, Jack states that the 270 Winchester came on the market in 1925 and he hunted with the 270 in a Win Model 54 in the first deer season it was on the market. He says he was one of the first owners of a 270 in Arizona and may have been the first man to shoot a deer with it in that State.

The O'Connor article is very good with much relevancy to the use of the 270 today.
