.22-250 Remington (using Hornady bullets)
Date: Oct 16 2013
The history of the .22-250 Remington began with the introduction of the .250 Savage (circa 1915), with records indicating the factory experimented by necking that case to .22 caliber, but that cartridge never became commercially available. By the 1930s several experimenters, including Harvey Donaldson, Grosvenor Wotkyns, J.E. Gebby, J.B. Smith, John Sweany and others, necked the .250 Savage to .22 caliber, and it became known by various names. Gebby trademarked the name .22 Varminter, which is the "wildcat" version most often encountered.
With the widespread popularity of these wildcats, Remington first offered rifles and ammunition in 1965, making the .22-250 Remington a standard SAAMI industry cartridge. Other major companies soon followed suit. Now, nearly a half-century later, the cartridge still enjoys brisk sales. The .22-250 offers flat trajectory, accuracy, high velocity and low recoil.
Factory loads offer a nominal velocity of 3,650 fps with a 55-grain bullet but loads are also available with bullet weights ranging from 35 to 64 grains. The vast majority of .22-250 Remington rifles are fitted with either a 1-in-12- or 14-inch twist rate, which generally stabilizes bullets ranging from 35 to 64 grains. Heavier bullets (68 through 80 grains) will require a faster twist to obtain proper bullet stabilization.
Much of the accompanying handload data containing the 45-grain Hornady "Hornet" bullet, exceeded 3,400 fps. However, in testing, bullets that exceeded this figure often disintegrated in air shortly after crossing the chronograph screens. As indicated, it is designed to give optimal expansion at .22 Hornet velocities; its thin jacket cannot withstand the high velocities and rotational speeds produced by the .22-250 Remington. For best results with these bullets, velocities should not exceed 3,300 to 3,400 fps.
There are many powders that more or less duplicate factory load velocities and yield excellent accuracy. Examples include IMR-4064, IMR-4007ssc, Vihtavuori VV-N150, Alliant Reloder 15, Accurate AAC-2520, Winchester 760, Hodgdon H-380, Varget, CFE 223, H-414, H-4895 and Superformance.
The accompanying data should not be used in wildcat versions, as chamber dimensions and case capacities may vary significantly and pressures may become excessive.
