I have always wondered why more development has not been made in revolver ammo. There are still a ton of models of revolvers out there and hundreds of thousands are bought and sold each year, new and old. Yet, with all this, the development of new rounds has been mostly limited to bigger and faster and not towards carry.
In the past few months. the .327 Magnum has popped up, but again, this is a longer case then the 32 H&R Mag, faster, and quite a bit more potent. This is a good little cartridge. in my opinion as it is fairly close to lighter weight .357 mag power.
My idea, though, is smaller rounds, more efficient, and able to compete effectively on a small scale with semi-auto pistol rounds. Let's face it, a 38 Special is a very large case for the performance it offers, which is fairly compatible to the 9 mm Mak or 380 Auto, with lighter loads.
How about we design a revolver round that is small, efficient and suitable for self protection with a smaller gun. No need for an X-frame sized gun,. How about something on a J-frame that can hold 6 or 7 rounds but still be at least as potent as a 9 mm Parabellum or maybe a 357 mag. We can do it. Powders can be selected to make the case as efficient as possible while keeping pressures low enough for a small, lightweight frame. Heck, we can take an N-frame, cut the cylinder length in half and probably still 8 or 9 cartridges into a revolver that weight less then most comparable semi-auto pistols and would be even more reliable.
Just an idea.... I hope one of the gun/ammo manufactures looks at one day
