Wildcat Evolution:
What is the significance of the following list of names: Newton, Ackley, Gibbs, and Gebby. If you answered 'wildcat cartridges,' you would be correct. Most of us have a knowlege of what separates a wildcat cartridge from a standard manufactured cartridge. And also understand the fact that some of today's standard calibers started out in life as wildcats.
One of the reason's some wildcats have become standard factory calibers is that there was a broad appeal for the cartridge and market surveys indicated that the caliber would sell in large numbers. Once this is determined, funding is generated for SAAMI ( www.saami.org ) standards developement. Once SAAMI standards are in place, any firearms or ammunition maker can be sure that any products manufactured to the SAAMI standards can be safely used. Two examples of former wildcats that became standard factory calibers are the 22-250 Remington and 25-06 Remington. Some of the previous wildcat calibers had an inherent high degree of velocity. I have a 25-06 and if I used some of the factory ammo available, I could possibly end up with a barrel burner. With the advent of more slower burning powders I can reload the proper bullet weight and slower powder (H4831) charge which give a closer to normal barrel expectancy.
When it comes to wildcat cartridges, P.O. Ackley was probably the most famous wildcat designer. One of the requirements of the Ackley improved calibers is that they could fire factory ammunition. This requirement allows a factory barrel to be rechambered, rather than requiring a brand-new replacement barrel' this helps to keep the conversion cost down. The Ackley improved series of cartridges offered an increase in cartridge capacity, by creating a minimum body taper in the cases. He also changed the shoulder angle to 40 degrees. Not only did the improved cases allow an increase in velocity, but also the cases would last longer and not needed to be trimmed as much.
