.32 rimfire

Enter the .32 NAA. As reported by Clair Rees in last November's issue of Handguns in an exclusive story, the new mouse that is making considerable noise hinges on a necked-down .380 ACP that launches a 60-grain .32 caliber bullet at more than 1,200 fps out of a 2 1/2-inch barrel. Much of the developmental work took place under the watchful eye of Ed Sanow, co-author of Handgun Stopping Power, Street Stoppers and Stopping Power, a series of books about real world ballistics. Sanow and Evan Marshall have spent a good portion of their careers looking at cartridges and how they perform on the street.

Bottleneck cartridges work well in semi-autos because they are shaped to feed naturally and headspace on the shoulder rather than the case neck. A bottlenecked cartridge can include a solid crimp, eliminating the possibility that a bullet might be dislodged as it is chambered.

The .32 NAA is based on a full-length .380 ACP case. Measuring .680 inches in length, the little hot rod features a short neck that is designed to securely hold a 60-grain .32 caliber JHP.

Typical of Cor-Bon loads, the .32 NAA round is designed for serious business. Launching a 60-grain JHP bullet, Cor-Bon predicted 1,200 fps and 192 ft-lbs of energy and the combination exceeded Cor-Bon's predictions. Twenty rounds averaged a blistering 1,204-fps with an extreme spread of 69 fps and a standard deviation of 19 fps on the Oehler 35P. The combination accounted for 193.09 ft-lbs of energy.

I love the idea. I also think the possibilities for a light carbine is fantastic!!
I have an ancient Winchester "High Wall" that was rebarrled to .30-06, more than I need and "pushing the limit" for a 100 year old gun. Changing it to .32NAA is very tempting, [but a simple rechamber to .30 Tokerov would be cheaper] The Tok would be more powerful but the idea is to make a small game/plinker, how much power do you need for that?? [Besides if more power was the plan why chage from '06 in the first place]? 1200 fps from 2 1/2" barrel should make over 1600 from a 20" seem very likely, sounds like more than enough for my purposes, and LOTS of fun.
