Fremont,
I ascribe to many of PO Ackleys ideas, but some are dated. When Mr. Ackley was improving this and that, H4831 surplus powder was about the slowest powder commonly available. Thus, an AI'ed 25/06 was not much of an improvement over a smaller cased round. The 257WBY really got going with the advent of Norma's MRP powder.
Today, we have loads of powders that will make cartridges which seemed "over bore capacity" really sing and shout. H-1000, R-22, R-25, 5010, 7828SSC, Ramshot Magnum and many more.
Well said; thanks. Hoping to use a Ruger No. 1 for the project.
