Highly esteemed writer Ross Seyfried wrote an excellent article in the May 2001 issue of rifle. While the main part of the article deals with shooting 22lf in 12G. shotguns the use of adapters to fire smaller cartridges is discussed. One interesting statement is "The most basic forms uses .22 rim fires in 22-caliber rifles, 25ACP in 25-caliber rifles & 32ACP in 30-caliber rifles". Long ago when I was hunting in some fairly remote areas like Northern Labrador I purchased 32ACP adapters to use in a .300 Win. for Ptarmigan. They worked as advertised at short range. Alex, Inc. in Bozeman, Mt. & MCA Sports in Alaska are listed in Seyfrieds article as sources.
