.327 Great For Defense!
A while back, I did a lot of research on ballistics. I looked closely at the speed and energy in various bullets fired from SHORT barrel handguns--the kind many prefer for CCW.
I would agree with most of the previous comments, and confine my purchases to mostly those calibers where ammo is fairly common, thus the .22, .38, .357, 9mm, .40 S&W, .44 Magnum and .45 ACP. However, for my research, I looked at several others, less common, but that in my opinion, are interesting from a CCW standpoint. Those are the .32 H&R Magnum; the .327 Magnum and the 10mm.
I have the data for all those calibers, but limited my results to short barrels--defined for this purpose as 3* inches or less. For those the data shows:
*Ruger SP101 3.063 inch barrel
The .327 is the FASTEST (1,356 fps) and SECOND in energy (469 fpe)
Ruger SP101; Gold Dot 115 grain
The only SHORT barrel with MORE energy was the .44 Magnum (611 fpe)
S&W 629-5 (3 inch, ported); Cor Bon 225 grain DPX
That makes the .327 a round that has great possibilities, especially in CCW REVOLVERS because of 6 shot capacity (J-Frames) vs 5 shot in .38/.357.
My point is that I do not consider this a dead round!
However, I do not own any weapons chambered for .327, and would not be likely to purchase as of this writing, because of low availability of the ammo and a shortage of platforms. But I WOULD--in fact--it would be second in line for a new purchase (for me) behind the KelTec PMR30 (which I think is cool because of 30 round capacity in .22 Magnum). All that is needed is for the manufacturers to get .327 platforms out, and the ammo to be readily available.
By the way, not to slight the .357 which was SECOND in speed (1,248 fps) and SECOND in energy (546 fpe) but the data was from a S&W 686 with a 4 inch barrel. Shorten that barrel by an inch, and the round would be slower, and less energy, and not that much more powerful than the .327, plus in a revolver of equal size, you'd have 5 rounds vs 6 rounds for the .327.
The 10mm (which I think is a great round) was THIRD in energy (533 fpe) but that was from a 5 inch Colt Delta Elite. Personally, I like the 10mm, but the ammo is expensive and not as readily available as the .38, .357, .40S&W and 9mm. I do own a 10mm (S&W 610 Revolver) that shoots both the 10mm and the .40 S&W using full moon clips. I love the gun, and love the thought of the devastating 10mm bullet, but would limit carry to dangerous areas (bears, wildcats, etc). That S&W 610 also shoots the .40 S&W, which is what I use for practice.
By means of this post, I am not "knocking" any round and think that everyone should shoot whatever they want--or can find--or make.
What I am suggesting is that the .327 should not be considered a "dead" round because of its extremely fast acceleration from a short barrel and strong stopping power and barrel capacity. Now if any manufacturers care to develop a pistol, that uses the .327, this could be a VERY popular round. (Kel Tec--are you listening?)
Hopefully, this post will give everyone some data on which to base your conclusions.
BTW--I own handguns in .22, .22Mag, .32H&R, .38, .357Mag, .40S&W, 10mm, .44Mag and .45 ACP. I do not, and probably would not purchase any other handgun calibers EXCEPT the .327! In a heartbeat!
